running track radius

running track radius

It isn't exactly the radius, it is the angle:  Using half or whole straights between half sections of curve(1/8, 1/12) can help for some trains.. Putting straight pieces between the curves does not change the radius.....it just puts straight pieces between the curves. A good rule is to use the largest curves and switches that space permits. You may be surprised to discover many trains will run perfectly on curves that are tighter than the specified minimum. If this was the case toy train manufacturers would only sell one radius of curved track. Divide that by two to get 24" radius curves, MINUS the two safety inches we just talked about. Most clear it, some scrape it. I don't understand where folks get this idea. This may be why many shelf switching layouts are popular. However, the car that is next in line will derail due to the coupler design. TRACK PLANS INCLUDES Layout plans for N, Nn3, HO, HOn2½, Sn3, and On2½ A SUPPLEMENT TO MODEL RAILROADER MAGAZINE 618247 • Layouts for 130 square-foot spaces and larger • Designs provide minimum radius and turnout information • All track … Lets say I want to run 48" engine/car on some 36" track … Other damage might occur to passing trains on the curve due to too much inside or outside overhang or to scenery and buildings just a little too close to the curve. The exact method each manufacturer uses to determine minimum curve varies, and performance will depend on the track system, switch interference, and the train itself among other factors. The train still has to be able to negotiate that diameter curve. Not all of us have the luxury of 072 or greater diameters. You want to keep the cars relatively close in length. My 26” curves seemed generous at the time but now the longer passenger cars just look like toys on this radius. An oval made of twelve 9" straights and a … This is turning into an essay, sorry...but there is a wonderful book penned by the late John Armstrong who was a pioneer in designing track systems for model trains. They do it, but not coupled, and will hit switch stands.). I picked up a couple of 3RS engines that I just couldn't pass up. Performance through curves and turnouts may differ. Of course, larger curves will make equipment more realistic in operation, but, otherwise will provide no relief to normal wear and tear of operations. Bachmann's exclusive E-Z Track system makes set-up quick, easy and fun. Years ago, there used to be more variety in the length of outdoor tracks, even for meets like the modern Olympics. A 2-6-0 may need 18” minimum but work more consistently with 22” or greater. Note that in many cases, it's not the locomotive that's the issue, it's the cars it's pulling. I have asked several times if a Williams Niagara and a Lionel challenger can traverse O64. It's rated for O54 track, but it'll happily go around O36 curves all day. 4. On the other hand, my MTH spine set is also listed at 042 min and handles the curves quite fine. Scott Mann has mentioned this in a couple of his posts. Drive the spikes just off the outer edges of the running … The turning radius, or turning path, of a vehicle is the smallest circular turn that it can make.Measuring the diameters, and commonly the radii, of the inner and outer circular geometries that … Typically, the inside area of the track accommodates all throwing events and a standard soccer pitch of 68 by 105 meters. You don't want body-mounted couplers. In North America, equipment for unlimited interchange between railroad companies are built to accommodate for a 288-foot (87.8 m) radius, but normally a 410-foot (125.0 m) radius is used as a … Except that radius would have one of your rails hanging out over the edge of the layout bench since the radius is measured conventionally at the centerline of the tracks....midway between the two rails. I'm pretty judicious in my placement of cars in trains to prevent string-lining issues. I have 0-42, 0-31, and 0-27 curves. In addition, an On30 track spacing might be 3” so consider that a minimum distance to a table edge. Really, when you think about it, a railroad comprises curves connected by tangents....tangents being straight lines coming off a circle. Like my Mikado. Running on less than recommended track radius. Radius vs. The later derivatives I don't know about (these are NOT the K-Line derived engines). Working with track centerlines, first offset the fixed-radius curve from the tangent and establish the transition length. ", Those are toy train  style radius . The standard track is made up of a circular half-circle of length lc= 115.61mfollowed … All the radius is is a straight line between a circle's dead-center and the rim...anywhere on the rim. These are only my personal preferences. More of each is ideal whether 2” or 10%. The biggest risks for anyone using smaller than expected curves are derailments and equipment damage. The T1 runs fine on that combination. Question #4 - Yes, a steamer with pilot and training trucks may derail, said steamer may just run off of the track. A 400-meter, regulation, eight-lane track with typical-sized event … If the recommended radius is 48", can I substitute 36" curved sections with straight sections interposed to come close to a 48" curve  radius or must I use all 48" curved sections? The next HO layout I built had 22 inch radius and worked great . Then there are also a few engines  where the manufacturer appears scattered and can’t make up their minds about minimum curve. So, on a sheet of plywood, 4 X 8, you get a width of 48". Now, having said that, I run my trains under the speced min curve all the time. When turnouts are not included, the min curve is usually less than the one posted. Here's a list of some of my locomotives: K-Line Big Boy - spec O31, does O27 just fine. What are (a) the track radius and (b) the period of the … Thanks for the replies, I am new to the hobby, I should have been more specific in my original post, I was referring to diameter. TA The A Train OGR Forum Member. I can't say if that is an issue with 2rs 3rs O, but small scale flanges and couplers don't like S curves IME. Derailments? Radius is measured from the center of the ties (mid point between the rails). Will you have a loop, or will it be an out-and-back like the real railroads tend to be? Long or inflexible equipment kept falling off the rails. But, required the wider turnouts. Maybe. Line each of the radius running marks at each end of the track with the same procedure. The Road Bike and Off-Road Bike options attempt to calculate routes that are most suited to these types of bikes.. Road Bike - avoids the busiest roads and any routes that are known to have unpaved … The turn radius is R. Running around a turn forces the runner to produce a centrifugal force F c in order to maintain his curved running path around the track… So you'll be good on O42 curves. What is the distance around the inside of the track? Length & width of paths are 140m & 3.5m and radius of inner semicircle is 42m. (not by radius). is advertised as running down to O-31. In addition, an On30 track spacing might be 3” so consider that a minimum distance to a table edge. Before I bought the heavy Mikado, I had asked about this, and someone with one of each emailed me with photos. Can the work on 18” curves? Tack one end of the stick along the tangent and then bend the stick to match the fixed radius of the curve at the end of the transition length. You must be signed in to continue. The stated minimum radius … Again, the best option is to test where possible. K-Line 21" passenger cars could pull this off but didn't look good. 3.5 is better; 4 and above is best. But don't expect a VL Big Boy to run on your postwar O-27 layout. It's your railroad, use a tender that will. So, keeping in mind what your locomotives and cars can handle for minimum curvature, you should always add 10% to that if you can. For one example, in the early 20th century 500m tracks … I think the locomotive would probably make it, but it looks funny without the tender along for the ride. This being the case, what is the “O-54 recommended” really intended to represent? Snap-Fit E-Z TRACK 26” RADIUS CURVED TRACK (5/card) - NICKEL SILVER Rail With Gray Roadbed - HO Scale. Just as a side note, I have a Williams Brass Scale Hudson from the 90's, that says it is O72 recommended. Many true O-scale 2-rail layouts use 72″ radius as a minimum curve (not O-72) – in other words a circle of track requires a room slightly larger than 12′ x 12′. Access to this requires an OGR Forum Supporting Membership. I have a loop of Fastrack the uses O72 easements into O36. Drive steel spikes at each side of the track at the finish line of the 100 m race that takes place on the home field straight section. Now you know you can safely lay 22" radius curves on your sheet of plywood, one at each end of the sheet to get your nice oval loop. Don't go smaller than the recommended radius. My take away is bigger is better if you can swing it. The less curved the tracks the better everything works,so try to find enough space to fit in a more user friendly radius if you want the layout give long term satisfaction....DaveB, Springfield: what are your must dos, must sees, must try's, must buys? I had a 3-rail Y6b from 3rd Rail that I could get through O54 curves, easily through O63. Is there a mathematic formula to determine a radius, or a chart. They allow a car that might otherwise require 48" radius (O-96) to negotiate 27" radius (O-54). If the Heavy Mikado can do it, I assume the light can. It's almost imperceptable. With lanes designed to be 400m in length from start to finish, 400m Running Tracks are the most commonly used track size that can easily accommodate for competitive sprint lengths of 100m, 200m, and 400m. A circle of 18" radius is 36" across, which is why about 40" is needed. The curves of the Pennsylvania’s famous Horseshoe … 3 Rail O Gauge, O27, Traditional, and Hi Rail, Tech Support for the OGR Forum (NOT FOR TRAINS), Automobiles/ Trucks 1/43-1/50 scale let’s see them. I have four industry spurs. The 2021 Big Book Catalog is Live! On steamers sometimes the locomotive can go tight, but the tender can't. The track comprises two semi-circles with a radius of 36.5 meters each. This assumes the bolster for the truck is in the center of the truck and you may need a bit more for three-axle trucks. I run scale-wheeled MTH engines and 2-rail cars now and everything I've bought so far has been able to handle 36" radius (O-72), but my 6-axle locomotives were all rated for 42" radius (O-84) primarily (it appears) due to coupler considerations. Assuming a 90 debree turn, you are going to need … Lionel Heavy Mikado - spec depends on where you read it as it's been listed as both O36 and O54, run mine on O36 all day long without issues. Using the circumference formula for the ends of the track … Running equipment on curves that are too sharp can grind on the flanges and the rail itself causing wear in both. I am extremely space limited. The radius is measured from the center of the track to the center of the curve. Athearn C44-9W requires 22 inch radius curves. So back to the drawing board'..Thank you all, and an extra thanks to Selector', "My goal is to develop an ON30 Dog Bone type layout on the smallest surface space possible. ", See if you can find the manufacturer's recommend minimum radius for the engine and cars you want to run then add a bit to the radius for insurance . My goal is to develop an ON30 Dog Bone type layout on the smallest surface space possible. Or they simply won't go as they'll get stuck, and you could burn out motors or drive boards as it's trying to push the train around. BRT/BMT 4th Avenue Line - Original Station Details, Converting an AF S gauge steel gondola to On30. I really need to hunt down one of them D&RGW locomotives. Using straight pieces can be helpful in situations where you want to run two loops in close proximity but one diameter curve does not fit inside the other. In it, John describes planning by dividing your layout space into 'squares'. Walthers B40-8W will run on 18 inch radius … Not risking it. A sprinter running on a circular track has a velocity of constant magnitude 9.0 m/s and a centripetal acceleration of magnitude 3.1 m/s2. A running track has two semi-circular ends with radius 24m and two straights of length 85.9m as shown. When you block a person, they can no longer invite you to a private message or post to your profile wall. In other situations, it's just a matter of what's coupled to it. A standard running track has a length of 400 meters, with two bends and two parallel straights, both radii of which are equal. The track … The book is called Track Planning for Realistic Operation. The figure below shows the contact forces acting between the runner's foot and the curved track. What are the actual adverse effects on the engines/ cars? On the other hand I have a collection of old time 1800 cars and locomotives which have no problem at all running on 18 inch radius track. Standard American Flyer track This iconic piece of American Flyer track had a 20-inch radius. Charlie started at the western most point of the track and at the same time, Alex started at the northernmost … However, I've been bitten on the caboose by uneven track (my Big Boy video illustrates that well) because the engines ride up on the center rail pickup rollers and the flanges can walk out of the track. Explain or show your … FWIW, the original Lionel scale Mikes--Southern, Frisco, and I think NYC--are all spec'd at 031. My VL-BB will not do an O60 curve, the tender derails right off the bat. Aim to Improve, Standard indoor tracks are 200m, but the Harvard indoor track is 220-yards – 8 laps, exactly, to the mile. To ensure long life and integrity, the base and asphalt are bound by an interior and exterior concrete curb during the running track construction. For anyone interested in running steam on smaller layouts, the as yet to be released Lionel BTO LEGACY 2-6-0 Mogul Steam Locomotive in various liveries (B&M, Rutland, Vermont, etc.) that describes how to determine a radius for a layout by sizes. Finding the greatest expanse at any place on your layout, you want a curve to double back if you want a loop. This is how the radius of the circular parts is set in order to obtain a 400mdistance on lane 1. A "straights between curves" "rule" is more for small scale and associated with backing, and "coupler tracking" /"coupler overhang" binding, etc. Can the equipment make it around with a similar piece of equipment coupled to it? Longer-radius turns (the American College of Sports Medicine recommends a minimum 20-foot inside radius) allow runners to maneuver the straightaways and the turns at the same gait. If it can run on 0-42, I'm OK but I've seen 0-36 and 0-54 listed. In the end, it comes down to experimenting, extensive testing, good track work (even without twists) and stable bench work (the moisture at the club is what caught up with me). The semi-circles are joined by two straights measuring 84.39 meters long. Considering the context of the OP's post, it is reasonable that he is referring to diameters and not radii. I have no passenger cars and only freight cars not more than 12" long. Prof Klyzlr. Whadaya getting? STILL SOUNDS TRICKY'. Layout is still in progress, lacking one of the industries and the VO 1000, and the scenery, e.g., roads, turf, trees, etc. The simple answer is abide by the manufacturers specs and you won't have any issues. When I talked to MTH designer during one of the OGR trips to MTH, he stated the min curve was tested for a complex turnout situation. Some wheels make contact with stirrup ladders on tight curves, brass models have many more details which may be ruined. Glad to hear this. We're sorry. Just keep track geometry in mind. For that reason, I only run 4-axle diesels with scale wheels at the club now and will be switching some of my 6-axle diesels over to hi-rail wheels or restrict their use to 2-rail operation. This can cause power shorts, derails, or damage to the pickup rollers. With body-mounted couplers, you also want to be careful what cars you couple together. 2. I use O36 curves and O48 switches. I go slow and watch it to make sure I don't damage it. FYI my MTH NJ Transit passenger cars listed as 042 min do not really like 042. I have a brass locomotive that needs 30" curve radius, according to the specs, so none of my curves are less than 30" + 3 = 33". Use a modern transformer with modern trains. For example, the Lionel Legacy 10-wheelers from 2014 state, “Min Curve: O-42 / O-54 recommended”, but a previous run of this identical engine from the 2010 catalog states “Min curve O-31”. Running on less than recommended track radius. A running track has 2 semicircular ends of radius 63 m and two straight lengths. shown in Figure 2. another issue would be with pickup rollers. At slow speeds they will stall and at higher speeds they will de-rail. Keeps the probability of increased wear and derailments low. Of course moving the machine to the other side is on my to-do list, I'm just pointing out that clearance issues are multi-dimensional. NEW LIONEL VISION STOCK, Golden St, New Arrivals! My switchers are an ALCO S-2 and soon (hopefully) an Atlas VO 1000. Each lane of the track could (by IAAF rules should) be as wide as 122 cm (4.00 ft), though the majority of American tracks are built to NFHS high school specifications that allow smaller lanes. Issues, derail and or extra wear and tear on the locomotive. The squares help to limit your curve radii and keep your track system workable and interesting. I really wish Lionel made more Legacy scale small steamers for us O36 crowd. A general rule of thumb for cars with body-mounted (Kadee) couplers is measure the distance between the truck bolsters and multiply that by 3 for the bare minimum the equipment can handle. Has anyone ever tried that on smaller diameter curves? Once the measurements are configured, the total length of the track… Though the Hudson ,4-6-4, looks odd, and the rear truck and wires make me worried looking at it. GP7's are the primary mainline locomotives. What ever radius it works out to be add a few more inches for scenery and safety shoulders in case of derailment.......DaveB, If you're specifically looking at On30, I'd recommend Googling "On30 Minimum Radii.PDF", Happy Modelling, E-Z Track is … I add 2" to that radius measurement for overhang, etc. The latest one, a MTH PRR FF-2 electric, was just irresistable. So, you divide that expanse by two to get the radius. The radius for HO can be smaller than ON30, unless the cars are modified to handle the tighter radius. I agree with all of the above. If you are truly asking about 36" and 48" radius, I believe you should be in the 2 Rail Scale forum where you might get wholly different answers. A 90 degree turn @ 24" radius equals 37.7" of track length - and that's down the center of the track. Also watch for the risk of string lining. O gage fastrack 036 curves vs 048 curves. Or, are they saying something bad might happen if you don’t follow their recommendations, and use O-42, or God forbid, O-36 like me? Sure it can do O36 curves, and switches, but I have to be really careful on O36 S-curves. Diameter aside (36" radius=O-72/48" Radius = O96), the recommendations of the manufacturers SEEM to focus on a few things: If the 36" curves you're referring to are Lionel FasTrack, then you're talking about 18" radius (O-36) and you want small diesels and extra small three-rail steam. Cutting out windows and doors in wooden sheet (clapboard siding), New Layout 2021.......updated as of 1/26/21. The main reason I say this is because I'm not personally aware of any 3RS equipment that requires anything larger than O72 curves. One of the 1st things I do with a new rolling stock is find out just how tight it can go. 12 pieces made a full circle. But that said, the OP should clarify. I decided it was going to run on my layout do or die (I have about 60 inch min). When backing the tender has come off the track. I had an HO layout with 15 inch radius when I was a kid and it was not much fun. However, I;m not interested in a switching only or a revering layout. This means that it's possible to fit an oval of Unitrack in a space as tight as 18 inches, or a double track in an area … in S curves,. 36 inches. 400m Running Tracks are specialized all-weather rubberized running surfaces used for an assortment of Track and Field competitions. From my measurements and experience radius is generally to the centerline of ties. It's a great little engine. For example, the Lionel genset switcher ambiguously states, “Min curve: O-42 / O-54 recommended”. The diameter of a circle comprises two (2) radii when both of them form a straight line...no kinks. However, this engine runs perfectly on my Super O layout with 36” curves! The VL BB, sure it could do O63 curve and switch, but any S-curve smaller than O72 will stop you in your tracks (Yup, I went there with a pun.). Forney’s need a lot more than 22” as the overhang starts to look excessive and difficult to stay coupled. Calculate the total distance around the track rounded to 1 DP. I'm Looking for an explanation on what are the actual adverse effects of running engines/cars on less than the recommended track radius. It is mainly an operating industrial complex, where switchers move cars to and from a specific (industry) spur to the mainline (loop). Finally, you'll never receive email notifications about content they create or likes they designate for your content. 400m Running Tracks have an inner radius … Lets say I want to run 48" engine/car on some 36" track curved sections. However, another gentleman on this forum has the same model from MTH and it will not navigate 036. I have small steam locomotives like Yard Goats (0-8-0) and Mikados. Then some of them long ones will hit, or clothesline on a curve. Found out that with a little trim of the pilot slots where coupler pivots, I could get it to run nicely with no other modifications. When Atlas and Third Rail (21 inch)coaches ride through the curve they hover over and span the switch machine. 3. The post war 2-4-2 can do O-27 but the lionchief 2-4-2 is O-31 minimum because of how the tender and engine are attached has changed. Bessemer & Lake Erie F7 identification... Lionel 2026190 UP 'flat spot' PS-1 Boxcar First Look, AM K4 Pacific won't run anymore...and I caused the problem, Need Help With remote control of older Fastrack 0-36 switches, SCRATCHBUILDING AN ALCO C415 - LOOKING FOR SUGGESTIONS ON DRIVE, Lionel Custom Runs for MrMuffin'sTrains - additional engines added, 3rd Rail F3 (RUN2) and Krauss Maffei, Reservations Closing, 2032010 LC+2.0 Santa Fe 0-6-0t Front Coupler issue. MTH Protosound equipped PRR T-1 Duplex - spec O72, just barley got it to do O48 but the motor was trying too hard (Pulling too much current. The field inside a running track is made up of a rectangle that is 84.39 m long and 73 m wide, together with a half-circle at each end. When thinking about curves one also needs to consider your rolling stock if you are running scale passenger cars. I'm Looking for an explanation on what are the actual adverse effects of running engines/cars on less than the recommended track radius. 24" X 36"; 36" X 48" etc. Our owner, Chuck Mears FAIA, founded Radius Track Corporation in 1997 based on his desire, as an architect and a contractor, to accurately and cost-effectively construct curved & complex building … As is normal, the switch machine is on the inside. Standard track. I plan when I start designing my layout to try and use O72, but having the flexibility to go smaller would make the design easier. Most locomotives can go down one sized curve, sometimes more like John pointed out, you just can't pull anything behind it. You are not the first. Which 3-rail trains will run on straight DC? The Mikado typically sits on its spur. ›, Good responses by all: Especially Selector', Received my AP Scenery Certificate, 1st certificate toward MMR, Scratch building a CNoR Third Class Station, Seven years in... (The late 7th anniversary of the Black N' Blue). Or is it more of a problem with consecutive curved sections forming 180 degree curves? Is there the risk of "string Lining" (the equipment hangs so far inside the curve that it gets snatched off the track). Note: if you proceed, you will no longer be following, $12.00 Per 12 Months, plus tax if applicable, The Track Planning and Layout Design Forum is sponsored by. 24 to 44 inches. How do you know if there is a problem? 5 is there a rule of thumb for the length in inches of a engine/car that would run on 36" curves safely? If you get a radius of 24", you'll need to lay circle arcs of 22" only to provide that 'shelf' for tumbling rolling stock. For instance, a Fastrack O31 curve does not fit "inside" a Fastrack O36 curve, but you can insert straight pieces into the O36 curve to "widen" it enough to fit the O31 curve inside it. Much equipment will work at slow speeds on somewhat smaller curves than recommended, but you will only find out what "somewhat smaller" means through trial and error. There is less angle when one truck at a time is on a curve (each curve must be short as the open space /wheelbase between two coupled trucks) It creates a jerky look though. The perimeter of the track is 1000 m. Find each straight length. Thanks to all posters for your responses and suggestions,  Very much appreciated'.. "Found this on the net today. You can obtain them from Kalmbach Publishing, Inc. In the case of locomotives, can the drive mechanism handle the curve? Start-Finish Lines. If you have a LHS that you are a regular at, they may even help you try it in the store before you buy (Did that with Lionel and MTH auto racks on O31. The Lionchief Plus NW2 and Hudson do O-27 because they are very close to the post war originals even if they are rated O-31. So best thing is if you really need to go smaller, lay some track out and slowly and carefully push/run it through the track and see how comfortable you are with it. The track consists of two semicircles with a radius of 36.5 meters and two straight paths. Or just extra wear and tear. Excellent point. You're probably limited to Rail King and Lion Chief locomotives. Get some track or rail and try it out. It is helpful to know that negotiating O36 curves is less troublesome than O36 switches, and so on with larger diameters. Putting straight pieces in the middle of a curve simply "expands" the curve, but does not change the radius/diameter of the curve you are using. Beyond that, to see if a particular combination works, you need to test it. lionel SC2 and Gargraves DZ-1000 switch question. In fact, for safety, since we have derailments at times, you don't want your rolling stock to fall off the layout at all if it derails and falls over on its side. Don't couple long cars next to short ones. Or rather, they are lines that intersect a circle at precisely one point. If you're running scale size large steam engines, in addition to the overhangs Chuck mentioned the trucks of the tender may jam in a curve. Lionel Visionline Big Boy - spec O72, locomotive does O54, tender will do O63, but doesn't really like it. The ON30  equipment I have will run fine on a 15 Radius. Lionel GG1 JLC (not "Legacy) truck restoration in brass. 1. I had forgotten about this one as my ten wheeler flies through O36 without any issues at all. Yes, measure radius to the center of the track. The ON30  equipment I have will run fine on a 15 Radius. And doesn't include curve approach-departure length. If you go on tighter curve track than it's speced for, the rollers could fall off of the center rail. I have an early '90 Lionel Chessie Steam Special T1. Tried spaced O-27 still no luck in getting it to work it would always derail. Depending on the age of engine, the other thing to keep in mind is that the variety of track we have these days didn't always exist, so for example an engine might run well on 063, but when it was built 072 was the largest radius and for example, the next size down may have been 042 , so it it was too big for O42 they might spec it as O72, so that could play into this (the more modern the engine, the less likely this is true, for obvious reasons). In general, large models like scale-length passenger cars, autoracks, intermodal equipment, and large steam locomotives will require a larger radius than short rolling stock … With the 3-rail trucks/couplers, you can get away with more because the couplers are truck-mounted and swivel in the curve.
