standard car wheel track width

H-36. Note: for the flangeways on the stock rails (the outer 2 rails of the switch) the spec is 2.69mm (0.106), 3.04 mm (0.120") (approx) Aristo gauge for frog 3.00 mm minimum (0.118"), no max specified, NMRA standard S-3.3 NOT SPECIFIED by G1MRA, Switchpoint spread maximum (??? Interestingly, car sizes have increased and decreased over the years due to consumer . There are significant compromises involved in using this standard, both in appearance and operation. This is the distance from the center of one wheel setting on the ground to the center of the opposite wheel on the ground. The short and simple answer is: Widening your rear track width gives you more understeer (more rear grip), narrowing your rear width gives you more oversteer (less rear grip). (Yes it is missing the levelling vials, they are held in with hot glue and always fall out, they are pretty worthless anyway except at a gross level). These cookies will be stored in your browser only with your consent. So let's try to get an overview of how these are organized. Turn the steering wheel so the front wheels point straight ahead. I think most people (and manufacturers) will use the old "Hi-Rail" standard 2/2010 "Deep Flanges" standard - S-3.3 - for deep flanges. Also there is an error in the standard. This is the entry point for standards. There are a wide variety of sedan sizes, from economy to full-size. Here is the root web page for all of their standards: https://www.morop.eu/index.php/de/ so you have to stay in German to navigate to the standards pages, if you are in English, all you get is a page of apology for not translating them sheesh, how long does this take? Most of the unibody cars got wider because of the disc brake hats. It is my opinion that the 1:20.3 people here in the US are much more concerned with scale and gauge than the 1:29 modelers. . spec) (at frog), ?? But the go/no go allows you some tolerance. (2) UK railway track gauge based on width of earlier tramways used to haul coal. S3.2 says: Again we have 3 classifications, and again, the Standard and Hi-Rail standards have been updated in February 2010. Because of the effect the wheelbase has on the weight distribution of the vehicle, wheelbase dimensions are very important to the balance and steering. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. (Yuck). Even then you should not use the huge, sloppy tolerances given. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Dimension A is the measurement from center of track to center of track. The length of a car is measured from the . Thanks all. wheel base (the distance between the front and the rear wheels) has to be larger than 200 mm and the track width (the distance between two wheels on the same axle) has to be larger than 160 mm. Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. Use it, it's only .002 deeper than the minimum spec, and you really do not want your flanges riding on the frog. It gives you the the understanding of the critical relationships between these elements, has nice drawings, and explains how and why guardrails keep a wheel from hitting the point of the frog, how a wheel traverses a frog without dropping in, etc. In my experience, using closer tolerances (similar to these new ones) combined with a better back to back setting on wheelsets, has VASTLY improved my ability to run more reliably through switches. Whats the difference between wheel base and track width? Best thing to do is carry a tape measure with you and measure everything that you see untill you come up with one that will work. Click here to see the G1MRA specification. This also implies sloppier and narrower back to back spacing on wheel sets (another historical situation with Aristo and LGB).

USAT SD40-2 experiences, including Kadee centerset couplers, USAT 44 Tonner Experiences & Kadee Couplers, Bachmann / Soundtraxx "Thomas family" OEM decoder, http://www.g1mra.com/pdf/standard-dimensions-for-gauge1.pdf, back to back gauge is 1.575" +.019, -.005, or a minimum of 1.570" and a maximum of 1.594". But the same minimum flangeway depth is just downright stupid. All of these were revised in February 2010. If you need to translate the .pdf files, click on the links on the Google-translated page. Conversely, as the wheel base length shrinks, stability is lost, but you gain in maneuverability. By calculating from the other specs, the flangeway width (on the stock rails) should be .097 min, .112 max for the guardrail width (on stock rails), but I would stick to 0.106 maximum. when the current NASG steel wheel-and-track gauge was first manufactured, the company that did the actual work, printed the text on the . Rear track being wider than front track will make the car turn in better. The tolerances make sense. 41" Tapes +14-0. In the case of an axle with dual wheels, the centerline of the . What is wheel base and track width? The NMRA, the G1MRA, and MOROP (who administer the NEM standards). Probably a mistake, but no one fixed it. Front tire wider than rear also helps in steering (decr. The flangeway depth is minimum 0.118 (3 mm). On average, you will find that standard cars and trucks range from 10-feet to 18-feet in length. Single Driveway: 20x10 minimum. Increasing the front more will lead to more oversteer which we already have a heaping helping of in our cars. M-33. A 4mm difference. . This is for toys. The outer 2 rails of the switch are called the "main rails", and you can call one the "straight" or "through" main rail, and the other the divergent rail. NEM is the name of the standard, and MOROP is the group that works on the standards. Thankfully H.J. Status Date. The standards are organized in sort of a top-down approach, so I start with the most basic and overall standards, and then go "down" in increasing level of detail. The cookie is used to store the user consent for the cookies in the category "Performance". Note also that what MOROP calls "large scale and garden railways" is not us. I think if you read between the lines here, EVERYTHING probably meets this standard, and the exceptions really take you back to the "wild west" of G scale. Which is better? Since most of the available standard gauge rolling stock is available in 1:29 scale, I will focus there. 1. Obviously what has happened is to set a "target" properly, but "Grandfather in" the existing manufacturer's toy like switches. Please note that while there are usually 3 sets of standards for each category, not all are applicable to 1:29 scale outdoors, so I list all the applicable standards, both approved and proposed. How does wheelbase affect the stability of a car? 7 Whats the difference between wheel base and track width? However, you may visit "Cookie Settings" to provide a controlled consent. This measurement is the track width. Necessary cookies are absolutely essential for the website to function properly. Don't use it for these functions. Why do you have to swim between the flags? I can get wheelbase pretty often but hard as hell to get track width. In my opinion, the new standards are good news, the Hi-Rail standards have been revised to much more reasonable specifications. The final Track Width measurement uses the average of multiple independent measurements in order to minimize errors associated with small steer angles. Sedans. So how does your rear track width affect oversteer and understeer? A switch is basically a construction that allows 2 or more tracks to combine to one, or vice versa. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. Then you drive on the highway as if you were driving a semi-trailer. . Larger front track width decreases this weight transfer. Well, as far as I can tell, there are only 3 groups recognized in the world that have standards applicable. Over the past few years we have had quite a few inquiries about track truck dimensions. Ground clearance: 4+ inches. The cookie is used to store the user consent for the cookies in the category "Other. What are annual and biennial types of plants? Others are concerned whether a tracked vehicle will fit on their trails or in between their crop rows for agricultural use. This standard allows for really deep flanges. Some of the stability can be regained through widening the wheel track (distance between the tires on a given axle). Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. Wheel base is 117-118 in, Measured track width , center of tire to center of tire 60 in. The shorter the lever the more the rear wheel is steered and vice versa. It defines the structure of the standards, and defines the terms: If you are not an expert in track (and even if you think you are! It will only tell you if the wheelset is grossly out of gauge, and will set different back-to-back measurements based on flange thickness/contour. for our data, which you resolve to access at your own risk. Passenger Wheels. S-10 rears are about 57 1/2 wheel to wheel, like most Fords of the 50s, 60s, and these all fit well from the 30s cars right on up. Vehicle dimensions . These are called "wing rails". CLICK HERE for the main NMRA standards page. Wheel track or track width is the distance between the centerline of two wheels on the same axle. This is simply because theres more time between the front and rear wheels hitting any bumps, so the car is less likely to become unsettled. I set everything to an exact value, rather than see if I am in range. Being an engineer, I am constantly investigating the factors that will make my railroad run the most reliably. ), I strongly suggest you read this specification (linked below). These cookies track visitors across websites and collect information to provide customized ads. so in most switches (except wyes and 3 way switches) one "path" is straight and one curved. It's 1.125 for the other "G" scales. Some of the stuff I have done has fallen around a 1.6 wheelbase to track ratio which is about in the middle of DUMPs range. You get the text, but not the illustrations. The wheel "gauge" is just plain goofy. Honestly it's really not useful for these functions except to tell you if you are WAY out. The moving assembly inside that actually causes a train to take a certain route is called the "points" and those rails are also called point rails. D. 40" Tapes +14-0. Before we go there, some explanation is necessary. A short wheelbase vehicle is usually able to corner faster but may be less aerodynamic. A standard width measurement on a car would be measured across the rooftop and go from the front driver side over to the same point on the front passenger side of the vehicle. This website uses cookies to improve your experience while you navigate through the website. The rail used for the track Wheelset dimensions are determined by the track gauge and the three items above and provide: 4. Picture kids removing their bicycle from the garage and allow enough space between vehicles to avoid a scratched car. Aristo gauge 0.097" NMRA standard S-3.3 0.100" G1MRA (Note target is 0.120"). Switch point spread - detailed in the document. While most U.S. railroads were designed by U.S. engineers, not British expatriates, a number of early lines were built to fit standard-gauge locomotives manufactured by English railroad pioneer George Stephenson. The part where the tracks "cross" each other is called the "frog". This cookie is set by GDPR Cookie Consent plugin. Measure across the tires on one axle from the outside of the tread on one tire to the inside of the tread on the tire on the other side of the vehicle, using a tape measure. It also has 2 prongs to measure track gauge. I use it's min/max feature to set my wheels. We also use third-party cookies that help us analyze and understand how you use this website. 8 How does wheelbase affect the stability of a car? STND 1956. (.118"). Also, "G" gauge track is appropriate for narrow gauge modeling, but the resultant scale for the track to represent 3 foot narrow gauge yields a rolling stock scale of 1:20.3. FIG 6. flange thickness is 0.059" + 0.002" -0.018. max depth of the flange is 0.066 (1.68 mm), back to back gauge is 1.575" +.019, -.015, or a minimum of 1.560" and a maximum of 1.594", stick with the NMRA "standard" standards, 3.2 and 4.2.

The Fora platform includes forum software by XenForo, www.geocities.com/lakota_circle_dancer/swap1, VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. To make this clear, once you have sloppy back to back tolerances, you have to increase the flangeway widths so much the wing rails and closure rails cannot support the wheel tread through the frog, and the wheel drops into the frog with a bump. For example, the 2004 standard has a guard rail flangeway width from 0.106" to as large as 0.131, and a flangeway depth of 3 mm. ie, a wheel of 8 inch wide with an offset of et 15 will stick out of the arch 20mm more than a set with an et of 35. Minimum width 10 feet, preferred 12 ft to allow car doors to open and step onto pavement. When I started this investigation, the Aristo-craft Track & Wheel gauge ART-11906 came on the market. Where you see the wheel size written down such as . Wondering if S10 frames would be ok. It measures 8.7 feet wide, not including the mirrors. I am not recommending the S-10, just pointing out the range of frame clips. Mueller translated the 310 standard for me: click here for a translation of NEM 310, (note, I also need to also check out NEM 313). If you want outside of tread to out side tread you would have to add a tire width. Hotrodding is much more than just owning a hotrodIt is a state of mind! Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. This is my recommendation since once set they seem to be good forever. In most scenarios, wheel track and axle track are the same length. How does wheelbase length affect handling? Rear wheels closer helps in attaining traction. RACK AND PINION. What has happened (as in many scales) is that with the track generally available in one physical gauge, you can use the same track gauge to represent different scales. Likewise, the track gauge is one measurement only. Cars with long wheelbases tend to have better ride quality than those with short wheelbases. They function like the guard rails in controlling the wheels as they move through the frog. However, in the case of offset wheels, the two differ. The early 2009 standard has a specification of 0.104", with a tolerance of - 0.002 and + 0.007 ( 0.102 to 0.11 ) much more reasonable in my opinion, and keeps the 3mm minimum flange depth. Turnouts are the #1 cause of derailments in model train layouts. Why is the length of the wheel base irrelevant? This sucks. It is way too wide. Originally I was very "hot" on this idea, but since you can buy a set of digital vernier calipers for about $20 at Harbor Freight, this is more of an exercise in convenience. Never use the maximum. ), Wheel back to back maximum (Aristo gauge perfect), Wheel back to back minimum (Aristo too wide/restrictive in all cases, the true allowable minimums are smaller), Flangeway width maximum (Aristo over spec) (at frog), 0.109" Aristo gauge 0.106" NMRA standard S-3.3 0.140" G1MRA (Note target is 0.120"), Flangeway width minimum (Aristo ?? I'm presently trying to find a donor truck frame to put under a 1941 Dodge 1/2 ton PU. Hoo boy, that's an endless debate! Equal. (This is the setting I use). Most of the unibody cars got wider because of the disc brake hats. FOR FREIGHT CAR SERVICE - CARBON STEEL (M-107/M-208) AAR Type. Anyonw know what the standard wheel track width is for the TL-01 chassis (tyre centre line to tyre centre line when viewed from front) Im trying to figure out what wheel offsets i need for my Bowler project, using a standard TL-01 chassis (no LA or B conversion!!) Assuming a 12.5 wide tire in DUMPs example and dividing wheel base by track width you get a range of 1.56-1.72. (1) U.S. track gauge based on UK track gauge. This means there has to be some "reasonable" route to make Aristo, USAT, Bachmann, and other 1:29 stuff conform to the standard, also track, especially turnouts. You CANNOT have sloppy specifications and loosen up the guard rails and wing rails and get smooth operating switches. Note: if you really want to learn and understand, then read all of this. People may be concerned whether a tracked vehicle will fit in their garage or on their car hauling trailer. It is within specifications, but I again would use it only for a rough check. It is only ONE page! Unfortunately, the February 2010 standards go backwards, with a specification of 0.115, +0.002 and minus 0.023". Aristo's "Plastic [In]compatible" ELECTRALUBE Legacy! By clicking Accept All, you consent to the use of ALL the cookies. (Yes, I know that 1:29 is not "purely correct" for the scale/gauge combination.). Also, indoor modelers can utilize standards closer to the actual prototype dimensions. I don't know anyone who can do this outdoors. J-33. The standard notes that the flange depth of 3mm is to accomodate deep flanges and results in flange-bearing frogs. This needs further research, but this sloppy spec is the #1 cause of wheel flanges hitting the frog. The 'Overall Width' of an L-Group vehicle must be as follows : 6.5.2.1. . I model large scale standard gauge. Please, don't use this gauge except to determine if a wheel has moved GROSSLY out of gauge. This works, as long as you have huge flanges, and ALL the SAME depth. In the case of a three wheel vehicle (LB or LE) or a motor cycle with a side car (LD), the maximum width must not exceed 1,850 mm. I hope you are getting the message that all this stuff is inter-related, and once you loosen the tolerances in one area it has a ripple effect all through the system. Wheelset designs for less common gauges can be found by adjusting the values given. OK, now we are on to the more detailed standards. It will increase the overall Track Width by 20 mm 2. It even specifies height of hook and loop (0.75"). OK, so maybe all of this is boring so far, but there is some relevance here: the scale you use can affect the standards you follow. 43.18 mm Aristo gauge 41.5 - 41.63 NMRA standard S-3.2 (Note, this is for I gauge, the NMRA does not specify this for G gauge in the S-3.3 standard, I suspect this would be relaxed in the S-3.3 if it was specified), Here is the link to see the standards:http://www.nmra.org/sites/default/files/standards/sandrp/pdf/s-3.2_2010.05.08.pdf http://www.g1mra.com/pdf/standard-dimensions-for-gauge1.pdf. accuracy of the information in our database cannot be guaranteed or verified, and we are 2.69 to 3.33 (0.106" - 0.131") NMRA standard S-3.3 (only for flangeways on wing rails (frog), and only if for "G" only, designed to accomodate older G scale, and wheelsets with a back-to-back of 1.542", and you can no longer run #1 scale wheelsets). 3. This cookie is set by GDPR Cookie Consent plugin. Dimension C is the measurement from outside of grease cap to outside of grease cap. There is also a note that says if you use flanges greater [thicker] than 0.076" you should reduce the back to back, but stay within the check gauge, and this is highly recommended. public databases. This means more grip. A standard 40-foot box car should weigh 5.75 ounces (2oz + (7.5" x 0.5oz)), or 163 grams for a 19.1cm car. We have been working to compile an extensive chart to detail this information. But opting out of some of these cookies may affect your browsing experience. Example: A wheel with an actual Diameter of 18" will have an overall diameter of around 19.5". unable to certify that a vehicle history is complete. It basically measures some range of the edges of the flanges, which is a terrible way to measure either back to back or gauge. I would file down the Aristo gauge to make it usable. Rack and pinion steering mechanism: 1 Steering wheel; 2 Steering column; 3 Rack and pinion; 4 Tie rod; 5 Kingpin. Some cars might be wider at the front end than back end. Before diving into numbers, a small explanation of my focus, since there are a lot of different SCALES that use "G" gauge track, 45 mm. Basically with the exceptions and sloppy and asymmetrical tolerances everyone is "grandfathered in" with no changes in production needed. Rack and pinion unit mounted in the cockpit of an Ariel Atom sports car chassis. A cars wheelbase is the distance between the centres of the front and rear wheels. Answer (1 of 2): There is no straight forward formula for this. Galvanized sub frame and wheel lift components Deck. Answer: Hot Wheels and Matchbox cars and trucks vary considerably in size, and there is no standard dimension. Those standards are for the ride-on scales. Due to the inherent nature of large scale trains, the wheel and track standards for "Standard" (Sx.2) and"Deep Flange" (Sx.3) are identical except in terms of flange width and depth, thus the track H depth also is changed. 6.5.2.2. This cookie is set by GDPR Cookie Consent plugin. I use the 5/2010 "Standard" standard - S3.2 - if you read this, you see that other than minimum flange clearance, this standard is the same as the 1/2006 Proto 20.3 standard - S-3.1 Now we are getting somewhere! Why does blood have to be infused in 4 hours? P-33. 1:1 scale, this resulted in different gauges. In the case of a two wheel vehicle (LA or LC), the maximum width must not exceed 1,000 mm. (So technically, there are no such things as "MOROP standards", only NEM standards.). Axle and wheel track are commonly measured in millimetres or inches. In automobiles (and other wheeled vehicles which have two wheels on an axle ), the axle track is the distance between the hub flanges on an axle. Track gauge maximum (Aristo over all specifications, allows too wide track gauge in all cases of all known standards), (Note that NMRA Approved Standard S-1.3 did not specify max or min gauge, but gauge was specified as 1.772" absolute) (Note here and in other measurements that the G1MRA original standard specified a target value with no tolerance +-), Track gauge minimum (Aristo gauge under specification, "too tight", would "fail" some track that meets other minimum specs), (Note that NMRA Approved Standard S-1.3 did not specify max or min gauge, but gauge was specified as 1.772" absolute, therefore using this part of the gauge with no tolerance will meet the existing Hi-Rail gauge standard. the flange depth is max is 0.079 (more sense than the NMRA 0.068) although they state you can use 1.5mm 0.059 if you want for sprung/equalized trucks. Some might confuse it with axle track, which is the distance between the hub flanges on an axle. The track width is hard to deal with since wheel offset makes such a difference. These cookies ensure basic functionalities and security features of the website, anonymously. The spacing between the wheels Standard values for track gauge follow from the scale being modeled as determined in step 2. Size An emergency vehicle may exceed otherwise applicable vehicle size limits up to the following maximum values: Width: 102 in. Using the This is what I want to avoid: (the combination of back to back and the flangeways actually has ripped wheelsets apart in some cases!) Trolley Wheel Width (W) 1/16" (+/-5%) 1.6 mm (+/-5%) Trolley Wheel Diameter (D) 1/8" (+/-5%) . The length of the wheel base will always be decided by its vehicle use. Please realize that there are many different scales that use "G" or #1 GAUGE track, 45mm. The vast majority of any car's interior sits between the wheels, so a car with a long wheelbase will tend to have a more spacious interior . Also the flange depth is nuts for outdoor use. A forum community dedicated to hot rod owners and enthusiasts. Increasing track width lowers weight transfer, increasing handling. Due to the inherent nature of large scale trains, the wheel and track standards for Standard (Sx.2) andDeep Flange (Sx.3) are identical except in terms of flange width and depth, thus the track H depth also is changed. I know this question has been asked before, I just can't find the answer, so here goes. Never go to the maximum unless you want to use G1MRA standards, just make sure the wheels are plenty loose on the Minimum part of the gauge, and just start to "climb" over the Maximum part of the gauge. None of the information is entered into the databases by ourselves. Aluminum - Conventional or dual angle - Extruded 6061-T6 decking DIMENSIONS AND TOLERANCES - ALL ENTRIES IN INCHES, EXCEPT TAPES. Height: 162 in. and im currently 100 miles away . The first section will list wheelbase, front track and rear track of vehicles in inches, so that those interested in frame swaps or clip swaps can find the correct donor vehicle. Answer (1 of 6): The number you are looking for is called the track width. Interestingly, the 4-foot, eight-and-a-half inch width has not always been the standard in the U.S. So, I will focus on 1:29 scale, standard gauge, used outdoors. More on this later, but it seems another political attempt to "grandfather in" deep flanges to keep the manufacturers "happy". 7. New, and gives the coupler height and tolerance for various scales. But different scales require different size and spacing of ties, and different rail "height", representing the different "weight" of the rail in the prototype which was sized to the weight of rolling stock and usage. It's supported by facts, but it's my opinion. 2mm deep flanges are tough enough, don't try 1.68mm. What crap this is, basically messing with the back to back makes your operation through turnouts worse, and this is the #1 cause of derailments. The stock track width is about 56" according to the factory shop manual. J-36. JavaScript is disabled. Use Google Translate to translate the page with the links, but then open the native French web page in another window/tab to open the standards and look at the .pdf files. CLICK HERE to view NMRA approved standard S-1. The standards that follow now refer to the NMRA's idea of 3 different classes of modeling: Proto & Fine Scales (where wheels & track are very close to exact scale) (NMRA standard S1.1), Standard (where wheels & track dimensions are somewhat "coarser" than exact scale - "standard modeling") (NMRA standard S1.2), Hi Rail (origin in the "high rail" of toy trains, our "Garden/Outdoor railroads" fit here in the NMRA's "mind") (NMRA standard S1.3). B-38. wheel base (the distance between the front and the rear wheels) has to be larger than 200 mm and the track width (the distance between two wheels on the same axle) has to be larger than 160 mm. If you only widen at one end, then that end will gain traction and the other will not which changes the handling balance. How does track width affect the steering geometry? In high performance vehicles a longer wheelbase is more stable at higher speeds. Answer (1 of 3): While cornering and braking weight transfer takes place diagonally that is from rear right to front left or vice versa. [1] Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. Is there a site or series of sites that give wheel base AND track width for various cars and trucks? It is easy though for people that are not as anal as me ha ha!. (avoid calling it the curved main rail, since there are curved turnouts also, and not all turnouts appear to have a curve) On the 2 main rails, there are 2 smaller pieces of rail called "guard rails". Well, both standards say flangeway depth is 3mm minimum, the SAME, NOT changed. If it is not obvious, the back to back spacing is so under gauge it's lifting the wheel treads off the rail head. This is the first combination gauge available, so I relate the Aristo gauge to the standards below to see if it could be a workable tool. This comes out to about 1.587". This is very popular in the areas outside of the US and England. Some are prototype standard gauge (1:32) and some are narrow gauge and the scales are quite varied. Ford cars over the years used the same rear end width, wheel to wheel, and advertised track width varied from -1 inch to +2 inches. Its therefore a smaller number than the cars full length, as measured from its front and rear end. File it down to meet the spec. Hot Wheels cars are available in f. Mine was not exact and needed a couple of whacks with a file to be right. Again we have three standards, depending on if you are Proto, Standard, or Hi-Rail. This is because it's difficult to make "proper" frogs in G scale, and flange-bearing frogs have their own problems. For most high volume production, this is usually mounted on the other side of this panel. Dimension D is the measurement from ground to center of hubs. Same car, different result dependant upon the way it's measured. Use standardard S1 to undedrstand definitions. . The length of the vehicle on nearly all vehicles is irrelevant because it it not extreme, until you get into the sphere of the stretched limo. Dimension B is the measurement from outside of track to outside of track. The July 2009 standard tightened this up again. Track Check Gauge - distance from flange side of a guard rail to flange side of a frog, Wheel Check Gauge - distance from the back of a flange to the tread side of the other wheel, Span - distance between flange sides of guard and wing rails, Flangeway Width - distance between flange sides of wing rail and frog, Flange clearance - vertical distance from railhead to highest obstruction below it, Flange depth -actual depth of the flange on the wheel. Exclusive of rear view mirrors, turn signal lamps, handholds for cab entry/egress, splash and spray suppressant devices, load induced tire bulge, a fixed step up to 3 inches deep. Axle track. Ford cars over the years used the same rear end width, wheel to wheel, and advertised track width varied from -1 inch to +2 inches. Come join the discussion about restoration, builds, performance, modifications, classifieds, troubleshooting, maintenance, and more! Wheel Width Measuring the Wheel width is similar to measuring the Diameter. 43" Tapes . The (Yuck). Choose the make of the car you are interested in and find out about its Wheelbase specifications. It has 2 rectangular slots on one side to "measure" wheel gauge. If you want a simple answer, first, there is not one, but you can read my "conclusions" section below, it's my opinion. I suggest if you have one of these, measure it and adjust it to match the tolerances you are working with (hopefully following a standard!). It's 1.063" for 1:29 & 1:32. (what sense does this make with a 3 mm MINIMUM flangeway? I will focus on the back to back specification, and only in the Hi-Rail standards as the new standard has another improvement in it that makes a lot of sense: In the new approved 1/2015 S-4.2 "Standard" standard: click here for the 4.2 standard (Note that the large scale standards are on the last 2 pages), In the new approved 2/2010 S-4.3 (old "Hi-Rail") standard "wheels with deep flanges": click here for the 4.3 standard (Note that the large scale standards are on the last 2 pages). Standard Vehicles. Another BIG change is that the Hi-Rail standards have been refined from being totally toy-like to something that will work better outside AND will allow long trains and better operation. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Well, both standards say flangeway depth is 3mm minimum, the SAME, NOT changed. You also have the option to opt-out of these cookies. This cookie is set by GDPR Cookie Consent plugin. In the prototype, i.e. The flange depth of under 2mm is nuts, run 2 to just short of 3 mm flange depth, too many of our locos do not have adequate suspensions. From a little G. The purpose of them is to keep the wheels on the proper course as the tracks "cross" each other at the frog. Looking at the frog, you will see space where the wheels are not supported as they roll through. For a better experience, please enable JavaScript in your browser before proceeding. Standard Steel currently manufactures a variety of types and sizes . Rear track being wider than front track will make the car turn in better. It will fill up the guards making the appearance "more tough" 3. The track width has to be determined first for determining the suspension hard points and geome. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. The widest title belongs to the Ram 3500 with dually rear wheels. 2 Car Driveway: 20x20 minimum, 20x24 is preferred. So, naturally I looked for standards, and I have tried to make sense of the ones I have found. If the car has positive Ackermann, the amount would be reduced by increasing the track relative to the wheelbase (lines projected along the steering arms would intersect further to the rear). This is the place that most people would "start" if they came from other scales and were in the US. Triple Driveway: 20x30 minimum. I know that there is check gauge which tries to combine wheel gauge and back to back, but the width of our wheel treads is so wide, that all you need is a proper back to back and a flange of the proper thickness and everything works out. Basic vehicle dynamics: the wider the track, the lower the amount of weight transfer. Check-In by 3:00 pm (no exceptions) Maximum length: 192 inches (16 feet) Maximum height: 85 inches. When measuring for the Actual Diameter, you will want to measure from the inside of the Barrel of the wheel (Shown by the Red Line in the above photo). Thanks for the reply and the web site has a lot of good info. I want a "workable" set of 1:29 scale standards, that improve the quality of operation, and have some chance of being used on current production 1:29 rolling stock. In the hobby, we represent this by saying:"code xxx" where xxx is height in thousandths of an inch, for example code 332 is 0.332 inches tall. For example, "G" gauge track is appropriate for 1:32 standard gauge modeling. Recommendation: file the Aristo gauge down in both places to meet the standard you want, I would suggest the Hi-Rail ones. It's not even worth giving a measurement here since it means nothing. Wheelbase to be 2290mm (90") minimum and 2693mm (106") maximum, wheel Track Width to be 2185mm maximum, Body Width to be 1500mm minimum and 1730 maximum, stiffening ribs included. I've also checked out the Kadee coupler height gauge, since it has a wheel and track gauge incorporated. When a disturbance (bump, wind gust) gives the front wheel an accidental steer input, a long wheelbase reduces the degree to which this also steers the rear wheel. We are reliant upon outside agencies The Chevy Spark is currently the narrowest on the road, measuring 5.2 feet wide. Regular road cars generally have wheels that are between 14 and 19 inches in diameter, with newer, more sporty, and luxury cars generally having the larger sizes. For instance: 86.0, 50.6, 50.3 -- 1952 Morris Minor. This is always referred to in inches, and as the name suggests is the diameter of the wheel - not the tyre and wheel together. The cookies is used to store the user consent for the cookies in the category "Necessary". The frog actually has several components, the point where the 2 rails in the middle come together, called the frog point (sometimes called the "frog heel"), and the 2 guard rails that sort of wrap around the point. Maximum width: 84 inches, including mirrors. Maximum tire width: 14 1/2 inches. A track width . The back of the wheel flange is limited in travel by the guard rails. ), Covered Hopper lowering and Kadee body mount, HW Conversion: 2 to 3 axle - Napa Valley Wine Train, Fitting roller bearings to plug door box vignette, LGB's freight Trucks & Mods for Car Lowering, USAT Intermodal Car & Kadee 907 Centerset Couplers, Kadees for Bay & Extended Vision Cabooses, USA Trains American Series Woodside Reefer & Body Mount Kadee 789s, Aristo 1st Gen Floors & Kadee Body Mounts, Aristo Covered Hopper, Lowering & Kadee Install, AML Reefers with Kadees and AML coupler boxes, Aristo Flat & Gondola, Lowered, Weighted, Centerset Kadees, Aristo Fruit Growers Express RBNX Insulated Box Car, Aristo GP40 Problems - Smoking Motors & Debilitated Wheels, Aristo Revolution 15 Amp Base Station Implementation with PWC / Linear control, Aristo SD45 Weights & Railing Installation, Aristo Signal Bridge ART-7110 Electrical Nuances, Aristo Tank Car with Body Mounted Kadee 907s, Custom Kadee Coupler Boxes for Aristo Locos, Kadee #1 vs. G couplers - Metal Coupler Box, Kadees for USAT Bay & Extended Vision Cabooses, USAT SP Hydra-Cushion Boxcar & Kadee 830s, USAT Streamliners with Kadee 906 centerset couplers, Aristo Heavyweight Passenger Car & Body Mount Kadee 907s, LGB Modern Tank Car - Weighted, Lowered, Kadees, LGB Center Flow Hopper Car w/Kadee Couplers, USA Trains Modern Tank Cars & Body Mount Kadee Couplers, USA Trains 60 foot Box Car Body Mount Factory vs. Kadee Knuckle Couplers, LGB Modern 50 foot Box Car & Body Mount Kadee 907s, LGB's American Standard Gauge 1/29 Scale Trucks & Mods for Car Lowering, Aristo FA1/FB1 Lowered & Body Mount Kadee 907s, Upgrading Aristo-Craft Loco Motor Blocks from Sleeve to Ball Bearing, AML High-Cube Box Cars & Kadee Body Mounts, GP7/9 & body mount Kadees w/3d printed components, Aristo 50 ton 2 bay hopper car & body mount Kadees. Was wondering if an S10 4X4 would work, have a line on an 1988 model. Once again thanks. K-36. Ideally, the cars are built to a 1/64th scale, however after owning many cars over the years, you start to see that this is more of a rough guideline. Even an A or G body GM is about 58" to 58.5". For those of us in "G" scale outdoors, the most recent changes is that Large Scale is now also in the STANDARD scale category. The cookie is used to store the user consent for the cookies in the category "Analytics". FIG 4. Another cheap sell out to grandfather in poor wheel standards from manufacturers. All we can do as a designer is to take reference from similar vehicles and then iterate the values on some software like Lotus Shark etc. The proper flange thickness also allows you to have nice reasonable flangeway widths, so besides looking toylike, it allows the wing rails and closure rails to work properly around the frog, supporting the wheel, so the wheel does not fall into the frog. Over the past few years we have had quite a few inquiries about track truck dimensions. Don't use it, use calipers to get to 0.106" or even less. Expressed as a measurement from outside to outside, front and rear track will be 70mm. Why are you allowed to use the coarse adjustment when you focus the low power objective lens? In real railroads, the angle of the frog is typically so slight that SOME portion of the wheel is always supported, or if not, the flange of the wheel will roll in the "flangeway" between the frog point and the wing rails. I'm disappointed by this, so my opinion is to follow the target values for the "standard" standards, not the proto/fine and not the deep flange standards. Please refer to our terms of The average width of a midsize vehicle is about 6 to 6.5 feet long. There's also some variation in the gauges I have measured. 1.793" NMRA Proposed Standard S-1.2 (Standard), 1.793" NMRA Proposed Standard S-1.3 (Hi-Rail), 1.762" Kadee track gauge (one measurement only on this gauge), 1.765" Kadee track gauge (one measurement only on this gauge), NEM 310 no minimum specified (targes is 1.772"), 1.755" Kadee gauge (Note: there are 2 notches, this is the measurement of the notches, when used to set an old Aristo "split axle" wheelset, it set the back to back at, 1.582" S-4.2 standard (standard 1:20.3 ) (Note target is 1.580"), 1.574" S-4.3 standard (Hi-Rail) (Note target is 1.576"), 1.574" S-4.2 standard (Standard LS) (Note target is 1.576"), 1.591" Kadee gauge (Note: there are 2 notches, this is the measurement of the notches, when used to set an old Aristo "split axle" wheelset, it set the back to back at 1.587", EXTREMELY dependent on flange contour), 1.578" S-4.3 standard (Hi-Rail) (Note target is 1.576"), 1.578" S-4.2 standard (Standard LS) (Note target is 1.576"), 1.574" G1MRA Standard (Note target is 1.574"), 1.567" S-4.2 standard (Standard 1:20.3) (Note target is 1.580"). The contour of the flange, the thickness of the very edge makes this really worthless. According to the Encyclopedia of American Business History and Biography, at the beginning of the Civil War, there were more than 20 different gauges ranging from 3 to 6 feet, although the 4-foot, eight-and-a-half inch was the most widely used. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. This is a favorite standard for people in England, and many narrow gauge modelers here in the US. I'll only include the "WHEELS AXLES AND TRACK, STANDARD GAUGE 1", as the fine scale standards are not applicable here. These are identified below. Front track wider than the rear. Use it as a rough check only. You can make it up some with additional tread width in the back, or a stiffer rear swaybar, or spacers. What did Britain do when colonists were taxed? Length: 20', 21', 22' Capacity: 12,000 lbs; Width: 96", 102" Steel - Conventional or dual angle - 3/16" diamond or smooth decking - Fixed or removable tubular side rails - Removable blade side rails. Unfortunately the official site has no English translation, here is a link to the applicable standard (a new one just for "garden trains": click here for NEM 311G. Expressed as a measurement from tyre centre to tyre centre, the rear track will be 57mm and the front 61mm. If you dont see your vehicle listed, please feel free to call or email. It will stabilise the vehicle as the wider track widens the footprint on the road The Rules in Relation to Track Width - Which is affected by Wheel Offset Track width on Passenger Cars must not be increased by more than 26 mm Where is the wheel base measured from? The G1MRA standard can be followed and everything will be fine, except the flange depth. Long wheelbase cars are often better looking, too. In the case of an axle with dual wheels, the centerline of the dual wheel assembly is used for the wheel track specification. Dave Goodsen recommends a flangeway width of 0.120" as a target. We are happy to help you find whatever dimensions you need. Ackermann steering geometry would be affected. The standards approved are still sloppy and have too much slop in them to grandfather older equipment and poorly manufactured equipment. Vehhistory.com provides you with access to material and information from An S-10, which is a somewhat popular swap, is about 54". LGB solved this with flange beaing frogs, that is, the edge of the flange rides on the bottom of the flangeway around the frog. Evaluating Average Car Width by Class 1. There are also some other exceptions on this page where back to back can be decreased to 1.542" and the wing rail flangeway increased to 0.131". There are no industry standard wheelbase sizes, but a typical city car might have a wheelbase of 2,430mm, while a family hatchback could have a 2,700mm wheelbase, and a large SUV's might be 2,980mm. Dimensions will be listed left to right as wb/ft/rt followed by the year, make and model of the vehicle. According to SAE Track Width is the lateral distance between the center of the contact patch. True. Check a earlier Dodge Dakota outI believe it will be close. Use the minimum part of the gauge to check the track, but if it's "tight" on the gauge, it could still be fine. Easiest way to increase track is to . The same is true of stability. Note: The MOROP standards are not available in English. Front and rear track the same. Vehicle dimensions with DOMINATOR tracks installed. service for more information. Easiest way to increase track is to fit wheels with a calculated offset/width . It does not store any personal data. someone help me out on this one). C-38. People may be concerned whether a tracked vehicle will fit in their garage or on their car hauling trailer. Others are concerned whether a tracked vehicle will fit on their trails or in between their crop rows for agricultural use.
