Use the tools> spacing-ring to check for track spacing, see: 2_041654_360000000.png For your wharf crossover, 1. delete from your plan the purple diamond-crossing and outer curve templates. 2. delete the inner curve and turnout to the control template. 3a. it is currently set to a curviform V-crossing. If that is what you want, click the tools> make ladder crossover> make curviform ladder menu item. This will be a shorter diamond-crossing than you have now. Extend it (F4 mouse action) to the required length(s) along the running line. or 3b. if you prefer a diamond-crossing similar in length to what you have now, change the starting turnout to a regular V-crossing. Then click the tools> make ladder crossover> make regular ladder menu item. Note -- you are making diamond-crossings across a transition curve, which is a bit ambitious for a Templot beginner. Ideally the new ...
... the side of the switch rail that touches the stock rail and the tables give the planing length etc But on the other side of the switch blade,( the gauge face) there is a some thining of the rail, with the foot left lin place, but are there any dimensions for how long the taper is on this side, In relation to the taper on top, for the undercut( no joggle) does that extend over the same distance as the taper with the rail foot remaining or is it over a shorter distance Ps, is it necessary to file the planing length on the switch blade gauge face, and bend it to bring it into a straight line running face? Edit: I hope Ive Made myself clear here. On the gauge face I'm referring to the small taper right at the end of the switch blade. As well as the overall taper on the gauge face I've seen reference to the overall gauge face taper as being the same as the blade taper in general, in other commentary, I've seen mention of give ...
103. Fan of sidings
... (off for another day in the garden: time to sow sweet pea seeds, and take some rose cuttings) Attachment: attach_3173_3811_scratch_for_fan_o ut_2020_11_07_1020_56.box 14 posted: 8 Nov 2020 13:43 from: Martin Wynne Hi Richard, There's quite a lot to think about for a fan of sidings. The first is storage capacity. Do you want roughly equal length in all roads? That means laying out the turnouts in a tree configuration with each road splitting into two. Or with one much longer road but each additional road getting progressively shorter? That means laying out the turnouts in a string along the inner or outer road. If the string configuration is laid along the running line, it has an advantage for model control in that to select a road only one turnout needs to be reversed, the rest being reset normal. So a simple rotary switch is sufficient. For a tree configuration a logic matrix of some sort is needed. Next is to lay out the siding alignments with sufficient spacing for running clearance, and for a fiddle yard with additional clearance ...
... simply disabling Avast, does not stopping doing somethings... Options seem to limited to having Deep Scan Off or On, I can't find a "first time only" setting. Best wishes, Howard posted: 9 Oct 2015 15:20 from: Martin Wynne JFS wrote: I can confirm that it is the Avast "Deep scan" which causes the delay. Hi Howard, Thanks for that. No doubt you are seeing the same thing with the FBR player, but it is a much smaller file, so shorter delay. Another issue with the EXE format is that it is not dpi-aware, so looks fuzzy on hi-res systems. I have been nagging Alex at EC Software about this, but so far he is not inclined to do anything about it. Individual users can change it via the file compatibility settings, but so far I can't find a way to bypass the manifest programmatically. There is also the problem that the usual IE keyboard shortcuts are not honoured, and the only way to zoom the text is ...
... crossover at 6ft way, the long timbers at the centre are 20ft long. The longest timbers in a single turnout were typically 15ft long, with interlaced plain sleepers beyond that. 4. timbers should not be too close together side-by-side, so that the gang can get a shovel under them to pack them with ballast to level the rails when needed. 5. likewise timbers should not be too close end-to-end. In that case either a single long timber is used instead, or two shorter timbers are halved and splice together to create a long timber. Such spliced joints have old fishplates bolted across them -- a nice modelling touch. 6. sometimes timbers must be moved from the ideal position to allow for point-rodding runs, signal wires, etc., and must sometimes be shortened at one end to clear catch pits, drains, etc. Here are a few links covering this subject on here: topic 2628 topic 2460 topic 1610 There are many more timbering topics if you do a search. ...
106. Blank after turnout
... close match seems to be a GWR 10ft switch with a 1:6 curviform crossing. See the diagrams here: http://00-sf.org.uk 00sf_10ft_6_v_peco1.png If you want to rebuild a Peco layout rather than make an exact copy, it would be better to use say an ordinary B-6 or A-7 turnout in place of the Peco Large Radius turnouts. You can probably save some space by reducing the track centres spacing to the scale 44.67mm dimension (except on sharp curves). If you are using the shorter Peco turnouts, I wonder whether 00-SF is the best choice, and you may do better in 00-BF. regards, Martin. posted: 8 Jul 2015 19:56 from: Godfrey Earnshaw Hi Martin, I think you are wanting to do more than I need. I can easily change out the peco turnouts, which are the large radius ones, for the best equivalent 00-SF. What I was trying to do was modify the existing templot drawing which utilises the Peco unit you have used ...

... -SA 3.0 in the Switched Diamond section. I have a couple of similar situations and I was unsure as to how the timbering would be dealt with but having seen this I think I might use this method. 3137_121655_330000000.png Is it common for the timbers to be arranged like this with alternate timbers having joints in the 4ft of the crossing tracks? It's not clear whether the last few timbers towards the concrete sleepers are similarly joined. Between the right hand tracks on the three before the concrete it appears that the sleepers might be shorter but it's difficult to tell with the ballast as it is. The left hand side is similarly vague. Since when would this arrangement have been used in such junctions? Thanks in anticipation Fraser posted: 12 Feb 2017 23:50 from: Tony W Hi Fraser. Yes, this would be a typical method of timbering such a situation avoiding overly long timbers in the process. Having gaps in the timbers in alternate 4ft ways is very common and you will find examples where two successive timbers have gaps in them although this ...
109. the Companion again

For example I was surprised to find that only 6 months ago I created this page: http://templot.com/companion/basics.php because I had entirely forgotten about it. And also this topic discussing it, equally forgotten: topic 3197 More importantly, that page still isn't linked from anywhere else, and isn't yet indexed in the A-Z Index. I think I had in mind that it was a temporary page, to be split into shorter sections at some stage. But I can't really remember. Perhaps a coffee would help...

... going towards the top of the plan and then generate a tandem to create the turnout that's part of the scissors- but if I were to build it in reverse, I'm not sure how I could make sure that the roads would line up and the road through the scissors would be at the correct 1:6 angle. Any ideas? posted: 10 Jun 2020 12:10 from: Tom Allen i think if you start it from a point, you choose left or right hand to define which is the longer or shorter side. Same with the size of the point. posted: 10 Jun 2020 12:27 from: Martin Wynne Hi William, Templot stops half-way through making a tandem to let you change the size of the 2nd turnout (within reason). In this case, if you start with a right-hand B-8 it works quite well, creating 1:6.27 (in EM) for the 2nd turnout. Then do this: 2_100716_250000000.png You can now make any of the usual adjustments to the 2nd ...
... around the world in that format, so there has always been a good case for IIABDFI. The shortcomings of such a format became obvious when I tried to recreate it in Lazarus for OT/MEC. In an effort to be cross-platform, Lazarus maps the Intel 80-bit Extended floating point format as the IEEE 64-bit Double format: http://en.wikipedia.org/wiki/Double-precision_floating-point_format http://en.wikipedia.org/wiki/Extended_precision Consequently all the type definitions in the Lazarus files are shorter and incompatible with the original BOX format from Delphi. I was forced to differentiate it as a new OTBOX format. If a way could be found around that, while retaining a fast binary format, there would be no need for a much slower text-based interchange format. I spent a lot of time trying to find such a solution, with only limited success. It should be possible because the conversions are built-in to the CPU registers: "The IA32, x86-64, and Itanium processors support ...
... railway company is going to go to the expense of long timbers without good reason. For example there is no reason to strengthen a siding by running long timbers across under it. But running lines are different. A complex junction with heavy traffic needs to be as strong as possible to minimise maintenance. Generally long timbers can be specified from stock up to 30ft long. Beyond that in one piece gets very expensive as a special order from the timber yard. Sometimes long timbers can be created on-site by halving and splicing shorter ones end to end. The rule which can't be broken is that the special switch and crossing chairs fit the rails in fixed positions, so there must be some timber under the rails in those positions. And for robust track the timbers need to be as square-on to the running rails as possible. Where there are rail joints they need to be as close together as possible within the limits of fitting a fishplate between the chairs. That usually means 24" or 25" centres under rail joints. But ideally ...
... the slide chairs. This does assume of course that some care is taken in making the set to achieve a stock rail which lies unsupported in the correct position before fixing. I wrote some notes about making the set here: topic 491 You mentioned switches going under-gauge, but this is surely only likely if an adequate set was not provided in the first place? If they go under-gauge because of thermal expansion, there is no plastic chair or adhesive on earth which will restrain them, the solution is a shorter length of rail and/or adequate expansion gaps. cheers, Martin. posted: 22 Apr 2018 13:31 from: Nigel Brown Hi Howard Think you're over-stating things. Problems with track which is subject to a wide range of temperatures are well-known, and stock rail isn't free of them; one solution might be building in a smidgen of gauge widening where appropriate. With layouts in a fairly stable temperature environment, then any problems are more likely to be due to the skill with which the track ...
... possible, and special one-offs only where unavoidable. At ends A it's unlikely that a bent flare would fit, so your machined flare looks about right. See the photos in the link below. The check rails could perhaps be shortened a bit though, timbers and chairing permitted -- you need rather more clearance for the backs of the wheels on the running rails at A. At B you might fit shortened bent flares, again timbers and chairing permitted. For machined flares in bullhead, generally the flared length is shorter than you have there. Again the check rails could be shortened a bit.

... when the turnouts are joined together to form the ladder, the resulting tracks from the diverging side that will form the storage yard are at different track centres to those set up on the crossover. regards Chris Last edited on 14 Aug 2018 14:23 by Chris Hodge posted: 14 Aug 2018 16:07 from: Martin Wynne Hi Chris, Templot works with prototype designs for the turnout lengths, it doesn't work as a set-track style program based on model geometry. For ladder tracks you may want to use a shorter turnout than a B-6, I suggest using A-6. Click the template> switch settings... menu item and select size A in the list. There is a trick you can use to get the ladder turnouts aligned with the yard tracks at fixed centres. Lay out the parallel tracks first and any crossovers between them. I have made you a bit of scruff video to show how then to get the turnouts aligned at each end, see: http://flashbackconnect.com/Default.aspx?id ...
116. Changes in 217a
... These main-road functions won't be needed very often, because the main-road exit is normally set via the overall template length. But they will be useful on occasions, for example where it is required for the main-road radius to change beyond the crossing. Previously that would have required a zero-length transition, with a corresponding change on the turnout side. Now a length of sleeper-less plain track can be pegged on over the timbers. Also useful where the main-road rails need to be shorter than the wing rails and check rails, for example when using V-crossings as partial templates in other formations such as a tandem turnout. See also the "second turnout close behind first turnout" video at: http://templot.com/sk5/switch_close_behind_v_crossing _.sk5 which now needs a bit of updating. 3. If templates have the trackbed edges/ ballast/ cess options applied, these can now be shown on diagram-mode outputs. For full details see: topic 3034- message 23076 Thanks to Phil O ...

118. video format
... topic: 3410 video format posted: 8 Apr 2019 16:39 from: Martin Wynne The shorter slide-style format for the videos seems to have been generally well-received, thanks for the feedback. So I'm minded to adopt that for all future videos -- it is certainly a much quicker and more relaxed creation process, without having my fumbling mouse movements being recorded while I'm trying to think two steps ahead. Which has prompted a rethink also on the means of delivering the videos. I'm still very disappointed that the HTML5 MP4 online image quality is so far behind the lossless quality (and much smaller FBR file size) available in the Templot video player. But maybe not so far behind as to be unusable, and certainly much easier to distribute -- and it works on all systems and mobile devices. So I think I will abandon the SK5 loader files and locally saved FBR downloads. That's all extra work to create, with plenty of things to go wrong, and mistakes to be made. I'm good at those nowadays ...
... diamond or slip it's best to start with the vees, as Phil says. That's because they need to be exactly the correct distance apart, to allow the other rails to align correctly. That also means printing a template for exactly the gauge which you are using. In other words don't try to build 00-SF 16.2mm say, on a 16.5mm gauge diamond-crossing template. Or 0-MF 31.5mm on a 32mm gauge template. Print one for 00-SF or 0-MF, it will be a fraction shorter. For a regular-pattern V-crossing on a curve, both legs of the vee should be curved to the same radius. Curve them after making the vee, to match the template. It's worth printing a rails-only copy of the template on tracing paper or OHP film. That can be laid on the rail tops during construction to check the rail alignments. If no tracing paper to hand, print on plain paper and punch some holes along the printed rails, so that you can see the rail ...
... Y-turnout. Note that there is a switch deflection in both roads, so this is not a turnout which can be used in a fast running line -- there would be a speed restriction over both roads. The effective deflection is only 1:48 each way, but that's still not something you want to hit at 60mph. 2_111124_470000000.png Despite appearances, this is implemented using an irregular half-diamond template, not a turnout. I set the K-crossing angle to 1:24 -- it could be shorter, but that looks about right. Then adjusting the V-crossing angle as before to get your required radius gave a nearest V-crossing angle of 1:3.42 I blanked up to the switch toe and put the peg on the split deflection position. Then I pegged it onto a short 2-timber length of straight plain track to form the switch front. The two sleepers were widened to 12" timber width in the shove timbers. In many cases the switch front could be part of an existing straight template ...
