... rail reach length, so that the far end of the check rail is aligned with the end of the wing rail, but this can be changed as necessary by entering the appropriate dimensions. These dimensions for the wing and check rails should be entered in full-size prototype INCHES and apply to the main-side (MS) wing rail and check rail (in the main-road of the turnout). The turnout-side (TS) wing rail (in the turnout-road) can be made longer or shorter than the main-side wing rail by setting a non-zero dimension for the turnout-side wing rail reach length modifier. The turnout-side (TS) check rail working length can be made longer or shorter than the main-side check rail working length by setting a non-zero dimension for the turnout-side check rail working length modifier.

22. My First Points
... fun! Your only worry might be if the entry planing on the check rail has not fully 'run-out' before the position where the opposite wing rail opens out for the crossing flangeway- if that were the case (especially in 32mm gauge) you might find the flanges striking the crossing nose- but then maybe you are not planning on running 8Fs or 9Fs! Yes Nigel, you are quite right- but then the GW did not use that much FB! I don't think I have ever seen an FB checkrail shorter than 5 sleepers- but I expect someone will post a pic of one! Best Wishes, Howard posted: 30 Jan 2011 18:54 from: wcampbell23 Hi Richard For a first effort it looks very good! I would make a couple of suggestions. As has already been commented the check rails are very much on the short side. I recently had the opportunity to discuss this with some knowledgeable friends (ex-BR and current Network Rail) and the very firm consensus was that the check rails should span a ...
... 12 Oct 2013 00:40 from: Martin Wynne Hi Andrew, I have dabbled on a bit further. I adjusted the shape of the island platform to better match the photographs: 2_111918_200000001.png 2_111918_190000000.png 2_111917_460000004.png 2_111917_450000001.png 2_111917_460000002.png 2_111917_460000003.png 2_111917_450000000.png 2_111934_380000000.png This is all very cramped. There was a trailing crossover on the right which was ludicrously sharp as drawn. To ease it I have moved the running lines and the goods shed further into the corner. Unfortunately this means that the trailing connection across to the down line has forced the down platform much shorter. It is now barely 4ft long. That connection may have to go. I will post the files shortly. regards, Martin. posted: 13 Oct 2013 10:41 from: Martin Wynne Hi Andrew, I'm no longer happy that I have the island platform correct.

24. 0-16.5 turnout
... spacings of timbers Given the locos have decent 00 gauge wheels I may go for 00SF as a gauge, using code 100 rail as in my opinion code 75 looks too skinny. As for build process I guess it will have to be either copperclad or spiked construction Thoughts as to both the design and method of building would be greatly appreciated Attachment: attach_2789_3368_0-16,5_A4.5.box 197 posted: 19 Dec 2018 11:56 from: Martin Wynne Hi John, Don't use REA switches for narrow-gauge. You will get a shorter turnout with an easier radius using the straight switches. Try changing to a 9ft switch for your turnout instead of "A" -- template> switch settings... menu item, top of list. Or save even more space by creating a shorter custom switch. There are some sample 0-16.5 (0n30) templates available for downloading here: topic 28 Also some templates matching the Peco 0-16.5 turnouts can be downloaded here: topic 2526 cheers, Martin. posted: 19 Dec 2018 17:32 ...
... template. 3. on its menu, click peg/align tools> make diamond-crossing at intersection menu item. 4. follow the instructions and wait a moment while Templot does the calculations. 5. you will then need to split the underlying original background template and shorten each half back accordingly. This method won't work as it stands for transition curves, it is for straights and fixed-radius curves only. Also it is very easy to have the tracks crossing at too short an angle. Templot can't produce crossings shorter than 1: 1.5 RAM( i.e. not more than 33.7 degrees). This method also works for two straight tracks intersecting, but in that case the result is a regular diamond-crossing. regards, Martin. posted: 29 Jan 2015 12:49 from: Robert M Dixon Hi Martin, Thanks for your prompt reply.

... down that road. Regards. Trevor. well, I asked, The master has replied. I would take my hints from Gordon of Eastwood Town fame, He widens the turnouts at the heel and toe back to 16,5, easy to do with gauges etc My view is thats the best rather then mucking with flexi posted: 24 Sep 2015 18:22 from: Martin Wynne More than 15 years ago, when I included the "EM minus 2" gauge/scale setting in Templot, I gave it the shorter designation "00-SF". At the time that seemed entirely reasonable, because it is intended that 00 models should run on it. But with the benefit of hindsight it was clearly a big mistake. I believe the reference to 00 has been a primary cause of all the argument and contention over the years. I don't think I can go on over and over again explaining 00-SF forever. The final straw has come today with a post on RMweb muddying the water with suggestions of using 16.2mm crossings on ...
... if they are in a visible scenic section, so folks can see trains held at signals for a reason, but delays caused by an invisible double junction are more difficult to explain. You can hardly have exactly symmetrical double junctions at both ends of the layout in view. So I think Rodney's suggestion is inspired and the best so far -- use the existing fiddle yard for the clockwise running and build a new inner one for anticlockwise running. Then there are no conflicting moves, and the new anticlockwise roads won't be any shorter than the existing ones. If you are looking for additional scenic sections, you could move everything back a few feet and introduce some plain track boards, possibly with a nice long sweeping transition curve into the existing curves at the front. If this was conventional DC, swapping the direction of half a fiddle yard might be a headache, but presumably with DCC it would require no physical changes to the wiring, just some re-programming of the point motors? regards, Martin. posted: 16 Nov 2007 23: ...
... 2) I want to make the six outer ones into double slips. I have done this as shown in my efforts in my previous postings but I have been thinking about the blade sizes to use. The defined blades only go to 1:6 whereas some of the angles are coarser than that. Does it make any difference if I use the 1:6 blades on a 1:5 crossing? Hi Fraser, You're a glutton for double slips! Unfortunately your slips are falling between two options. An inside slip shorter than 1:6 is all but impossible, especially in 00 -- unless you are going down to Peco geometry. A 1:5 inside slip would have an excessively sharp curve in the slip roads, and even the usual short 1:24 blades would be too long. On the other hand, for an outside slip you would normally want a diamond shorter than 1:5, otherwise it is going to be very long, and you would have trouble finding space for the switches. Instead of having all ...

... . Most commonly the diagonal-road is more sharply curved than the main roads, creating short diamond-crossings. The diagonal-road follows the initial curve of the turnout-road (or can in some cases be straight across curved main roads). Curviform ladders are comprised of curviform diamond-crossings, and are often used to form running-line double-junctions, and to gain access across running lines to goods yards, engine sheds and industrial sidings. Slips are less common in curviform ladders because of the usually shorter crossing angles. The type of ladder track is determined by the type of V-crossing which is currently set for the control template. To change it, cancel the ladder and first click the template> V-crossing options... menu item. Change the V-crossing type as required. Then click the tools> make ladder crossover menu item again. For a regular ladder set a regular or generic V-crossing. For a curviform ladder set a curviform V-crossing. N.B. If you wish ...
... of baseboards you should use the "background/shapes" menu option. There you get options to draw various basic shapes and the one you would probably want is rectangle. When you have selected that you can then choose to enter the dimensions or draw it graphically with the mouse. For exact measurements, it is probably better using the measurement entry option where you are asked to enter the co-ordinates for two opposite corners. For your "L" shaped baseboard you might want to draw the longer leg horizontal and the shorter leg vertical. Also the basic measurements in Templot are metric (I know there is a way of entering Imperial but I can't remember at the moment) so converting your longer leg of 12' x 2' to metric gives a metric size of 3658mm x 610mm. So your first point for the rectangle would have X= 0 and Y= 0 and the second point at the opposite end would have X= 3658 and Y= 610. For your second rectangle of the shorter leg, the length would be 2438mm ...
... a quick dabble on your rough plan: 2_091645_400000000.png Templot will go down to 1:1.5 angle. As you can see your crossings here are around 1:2.5 so easily within range, and it's easy to get the basic alignments using make diamond crossing at intersection in TDV. At these short angles the timbers will need a bit of shoving to tidy them up. By a "flat crossing" I think you mean a short-angle crossing? I don't know of a specific limit, but Templot doesn't directly support anything shorter than 1:1.5 At those angles the prototypes vary a lot and tend to be made up as one-offs. Below 1:1.5 in Templot you can only overlay plain track and then either mark up your prototype on the print, or create a mass of partial templates and shoved timbers.

... a double slip. Slips are often arranged in a ladder formation diagonally across several running lines. To replace them all with double turnouts would use vastly more space, and also mean traffic on the ladder road would be subject to repeated reverse curves. p.s. such turnouts are toe-to-toe, not heel-to-heel. Similarly what would determine whether to use an inside single slip vs outside single slip vs half scissors configuration. This is usually down to radius and crossing angle. Inside slips are generally not shorter than 1:6, the slip road is very sharply curved at that angle and subject to a severe speed restriction. You wouldn't find a 1:6 slip road as part of a running line. Outside slips allow a much easier radius and can be used at shorter crossing angles, but require a lot more space. Here's a nice outside slip. You can see how much longer it is than the diamond-crossing. It would be an impossibly severe curve as an inside slip entirely within the diamond: outside_slip_shrewsbury_1978_600.j ...
... prototype you are modelling? Finding one matching 16.2mm gauge is a bit of a challenge. On the GWR it is an angled bolted half chair instead of the L1. Here's Phil's pic of one: 1_single_jaw_chair.jpg The REA design uses an M1 chair instead of the L1, and an SP chair instead of P. M1 is a smaller version of L1 -- 8.3/4" long instead of 10.1/2". Do you want a scan? Sorry I don't have a drawing of SP, still looking. It's obviously shorter than a P. cheers, Martin. posted: 15 Jan 2018 19:43 from: Andrew Barrowman Thanks Martin. I have the M1 dimensions. Just need to create the model. I'll need it in other places anyway. I would imagine the SP is just a bit shorter. That wouldn't be difficult.

... Fine Detail plastic from Shapeways. There seems to be several out of dates pages on the site made more confusing by the fact they changed the names a while back. One thing I hadn't noticed before with the two makes of moulded chairs was the difference in the keys. The six 3-bolt running chairs in my pic are by both C&L and Exactoscale. The keys in the C&L ones stick out of the chair jaws a long way and are quite skinny in cross section- the Exactoscale ones are shorter and fatter and actually fill the web of the rail meaning they hold it more firmly. The 4-bolt chairs are all Exactoscale ones as they were all I had to hand. The base of the C&L chairs tends to bend as Peco rail is threaded sometimes even fracturing. The Exactoscale ones don't but are still easy to thread onto the rail. The Shapeways ones fit the Peco rail fine although it is obvious that they are more likely to break if care isn't taken to smooth the rail ends and offer ...
... the Y-turnout by making a curviform crossover instead, as shown in the lower part of the diagram. In this case the straight turnouts are B-7. I did tools> make return curve to create two overlapping curves. I then created a curviform Y-turnout and aligned it over the curves at the fine point intersection. The result was a Y-turnout with a 9ft switch and 1:5.55 crossing -- i.e. a longer Y with an easier radius, even though the overall crossover is much shorter. The Templot Development Version (TDV) contains some new functions which make it easier to find such intersections and determine the crossing angle. regards, Martin. posted: 6 Aug 2011 20:30 from: Martin Wynne Hayfield wrote: If I convert an A5 turnout to a Y turnout does the crossing angle of the Y become 1 in 10 for each road.

It's probably better than mine (I'm in the USA) Andy posted: 9 Dec 2017 22:04 from: Martin Wynne Hi Tim, We need a bit more information about the type of trains which you are planning to run. These very short turnouts are suitable only for trams (trolleys?) or cramped industrial sidings. For these turnout sizes you need to change to a shorter switch, the one in your screenshot looks like an REA "A" switch. I suggest changing to the 9ft straight switch. You can then get a return curve within 100mm at 1:2.75 angle, if you remove one timber from the switch front: 2_091652_370000000.png But as you can see, the radius at 1:2.75 is down to a mere 3". You could get it shorter, or an easier angle for the same length, by reducing the track centre-to-centre spacing. But that ...

... zone section within it is too long? If the transition zone is short enough to fit, simply shorten the template at one or both ends as necessary (F4 mouse action). If the transition zone is too long to fit the space, try the adjusting the radius of one or both of the starting curves until the gap between them is smaller: make_t3.gif Zoom in if necessary. There must be a gap, i.e. the curves must not cross, but the smaller you can make the starting gap, so the shorter will be the resulting transition zone. If you can post a screenshot here or attach a .box file, it's much easier to advise. regards, Martin. posted: 1 Apr 2012 20:04 from: Adrian (ffoil) Martin Wynne wrote: Adrian (ffoil) wrote: I can get it to generate curves, but at least one end is always beyond the limits of the curve that I need to create (if that makes sense).
