... ). I can not get the dimensions less that about 10.5 meter without altering the V-Crossing to less than the 1:7. 1:7 is correct for all the other dimensions. I can not find a solution which allows me to reduce the Joint-FP length. Hi Paul, Which joint do you mean? It would help if you could post your prototype drawing. Try action> mouse actions:control/real> adjust V-crossing entry straight (or SHIFT+ F11) mouse action to shorten the lead length. I'm going to rename this topic shortly because the reference to an image is misleading. regards, Martin. posted: 15 May 2013 19:09 from: Franz Martin Wynne wrote: Which joint do you mean?

... to my attention. At present I just use a straight template and F7 to join it, F3 and F6/ transition to take it where I need it. I rarely if ever use a constant radius other than the corners of my hidden spiral. I would generate the inside one larger than a quadrant. Set it in the corner and store. I then generate a straight template and overlay it visually to align with the curve. Get a pair of sleepers overlaid exactly to ensure the join is perfect and then F3 to shorten it. Flip back to the curve and adjust length using F3. Set up the parallel curve for the outside and job done, so no F7 in that case. Now something perhaps slightly different. If I have say an engine shed, I will put it where I need it on the layout and add a straight template which has been rotated to the right position. If I cannot get the branch track to align with the straight smoothly then I'll start from both ends as it were and extend both pieces of curved ...
... between the switch heel and the crossing nose, it gives less angularity to the turnout road. It's no big deal to do this if you are building your own track. Many thanks. Yes, I tried that. But it doesn't flatten the diamond enough to make a slip road feasible. As shown the the angle is 1:6.5 which is still tight for a slip in P4. It might work if the angle down the platform road is much reduced, but that changes the scenic treatment at the end and also shortens the clear lengths in the platform and the head spur. May be worth a try to see how it looks. regards, Martin. posted: 29 Jul 2007 20:29 from: Rextanka Hi Martin& Everyone, Thanks so much for looking at this, this is one of the great things about Templot because for every layout to this point I've always been a little frustrated when, having roughly laid out a couple of C&L templates and convinced my self a plan will work, when the actual track goes ...
... the slip road. Hi Peter, The problem here is the wider than scale flangeways. Even the prototype has problems with clearance -- the ends of the K-crossing check rails have a little machined off the top, so that as the slip road rail wears, overlapping wheels do not strike and dislodge the check rail. The wider than scale flangeways in 00 and EM just make matters worse. But fortunately differential rail wear is one factor we don't need to worry about in models. There are three options -- shorten the check rails, or flatten the slip curve away from them (or both), or alternatively change to a switch-diamond (movable K-crossings). The latter would look odd and non-prototypical on slips of 1:8 or shorter, but may be the best option in a fiddle yard. Flattening the switch curve is done by using shorter switches in the slip, i.e. for the 1:7 slip use the slip switch intended for 1:6 slip, for the 1:8 ...
... : 23 Mar 2008 19:58 from: Martin Wynne Hi Richard, On loading another copy of Templot, this time I was asked if I wanted to reload, I said no, and managed to get the Half Diamond Check Rail to function as expected. So I guess my question is: what settings is effecting this function? Can you clarify whether you are referring to the V-crossing check rails or the K-crossing check rails? A half-diamond template has both. There are some additional controls for shortening the V-crossing check rails on a half-diamond template to clear slip switches, which may account for the effect you saw, if these controls had previously been used. Check rails are the biggest headache and over the years I have changed the code several times to try to cover all the situations which arise. It is still confusing. The difficulty is to allow you to change them to whatever you want, but still have Templot know what to do with them when you change the crossing angle. Waiting in ...

My example is certainly not how I would lay it out but was deliberately meant to make it so that this easy way of joining was not possible without altering the existing track. I suspect that it is going to need a reverse curve of some sort. posted: 3 Aug 2019 14:01 from: Martin Wynne drrsenior wrote: Thanks.That does work BUT if for example the second track was in the engine shed then it now has around 600mm less of straight track as it was shortened ...
... , etc. Is this a general thing or just for P4 Track Co designs? Hi Richard, It's a general thing, but depends on your prototype drawing. If the drawing shows the turnout curve terminating at the fine point (gauge intersection, CTRL-4 ), use a generic V-crossing. If the drawing shows a straight section in front of the V-crossing, use a regular V-crossing and set the required entry-straight length. Introducing a straight section in front of the V-crossing shortens the lead length -- the prototype sometimes does this on natural and sub-natural sizes where space constraints dictate and changing the crossing angle is not possible. In version 091c you can adjust the entry-straight by mouse action to see the effect and shorten the turnout as required (action> mouse actions: real> adjust V-crossing entry straight menu item). Templot defaults to a regular type crossing anyway, so that the rails are symmetrical at the knuckle for easier building and smoother running. The shorter lead ...
... [ max spiral] setting permits. For a C-curve transition, this means that there must be a sufficient difference between the two radii. For more information click the[ program> expert> transition maths> max spiral...] item on the[ program panel] menus. The new control template will have a 1 chain (66ft) (scale) length of 1st radius before the transition start position, and a similar length of 2nd radius beyond the transition end position. The final task of extending or shortening the new template at each end, and/or doing likewise with the original templates, in order to position the template boundaries and create a full linking template between them, remains for you to do. (Put the fixing peg at the opposite end and then use the F4 mouse action to adjust the overall length). Often when using this function the original templates are dummy templates created solely for the purpose. These are then deleted and the new transition template is extended at each end to replace them. If the ...
... 27,675mm X= 1,0896 inches Thus the offset at the new heel is: 6,25"- 1/8"+ 1,0896"= 7,2146 inches Based on that I get the following figures for the switch: Lead lenght to heel: 16'6 "+ 2'10,5 "+ 3,96"= 230,46 inches Offset at the heel: 6,25"-0 ,125"= 7,2146 inches Now, this might make things difficult, but I decided to shorten the distance from the stock rail to switch joint. Stock rail joint to toe: 4'6"- 3,96" (distance to vertex point)= 50,04 inches This should preserve the overall turnout lenght, and hopefully without messing up the geometry. I also changed the v crossing to CLM units and made it a 1/2" blunt nose. I also think I miscalculated the lead the other day. 68' should be 129,54mm I just have to go through this when Im less tired ...
... : William Williamson Thank you again- unfortunately it's ended up with one of the legs being too long and intruding into the middle of a diamond, I was hoping to slot an outside slip into the location to ease the angle of the Peco one- is there anything I can do that'll help? Original: http://i.imgur.com/LYlVFqh.png With the templot outside slip: http://i.imgur.com/7b4poB3.png You can see in the second picture that it's across the diamond. Is there something that can be done to shorten that side of the outside slip?

That's the problem with an outside slip, it ...
... lines are curving in opposite directions? It's on the left hand side of the track diagram. Hi Rich, That's the easy one. Starting from your posted file, click on the background template and then peg/align tools> make diamond-crossing at intersection menu item. In this particular case Templot finds the wrong intersection first. Click the try other intersection option. Then afterwards use F4 mouse action to extend the template into the gap. As you can see, Templot doesn't do everything: 2_010937_130000000.png You now need to shorten the original background template from under the diamond. And because the diamond is so short, there is quite a bit of timber shoving needed to tidy it up. For which ideally you would have a drawing for your chosen prototype. Short-angle diamonds vary a lot. But don't bother with timber shoving until you know you have your finalised track plan, otherwise it is wasted work if you make changes. Note that in your file you also need to reset geometry> centre-line options> main road (normal ...
... timber shoving. For modern flat-bottom track you will probably want to start square-on and only change it for diamonds and slips. The special crossing chairs must fit the rails in the specified positions, and must have a timber under them. This generally limits you for the amount by which the timbers under a V-crossing can be moved forward or back. These will generally be the Y- X- A- B- C timbers*. But you can skew them a bit more or less, and shorten them or lengthen them under an adjacent track, so that a timber comes under the correct crossing chair positions for several V-crossings. Placing short timbers end-to-end, or long timbers side-by-side makes it much more difficult for them to be packed and tamped. Skewing timbers is called "twist" in Templot's shove timber functions, using the twist mouse action or the cw and acw buttons -- which rotate the selected timber by 1 degree of angle for each click, or each press ...
... 2020 22:21 from: Martin Wynne Paul Boyd wrote: I hope this isn't something new for you to fix! Hi Paul, Thanks for the feedback and BOX file. You probably noticed that when Templot creates a diamond-crossing at an intersection, it leaves the diagonal-road exits on the minimum TMINP positions. There's a reason for that -- it's to minimize the effect of the error you found. What you are intended to do is use a copy of the original underlying curve for the connecting track and shorten it to that TMINP exit. Rather than extending the exit from the half-diamond. Of course I have rather thrown a spanner in that with the new OS peg positions. Especially if you then go and extend the switch with some approach track. The new code which I have been working on today will definitely improve the match to the original curve. Whether it will eliminate the mismatch entirely it's too early to say, I need to do a lot of testing to be sure I haven't broken anything. It's looking ...
... also with the Templot P4 templates Thanks in advance John posted: 17 Apr 2017 11:40 from: Martin Wynne Hi John, EM templates are shorter than P4 templates. That's just basic geometry, resulting from the narrower track gauge. So in EM there may be fewer timbers and they may be different lengths. There isn't actually an REA spec for the number of closure timbers between the heel of the switch and the crossing, it is down to each company to specify their own designs. Also the lead length might be shortened if necessary for a particular site by increasing the crossing entry straight. You can't have a fixed timber spacing across all sizes because of course there has to be a whole number of timbers accommodated within the available closure length. I'm a bit puzzled how you are going to use the P4 bases for EM because they have pips locating the chairs at P4 gauge? Note that some of the Exactoscale bases have an intentional error in the position of the wing rail joint and the corresponding closed-up timber space. Len and Andrew ...
... timber in fresh air between the timbers, aligned to the FP intersection mark. Which again looks awful. If you want to use sharper vees, you need to print new templates after adjusting the blunt nose width at real> V-crossing options> customize V-crossing> blunt nose... menu item -- click the? info button on the dialog to read more about this. Templot will then adjust the timbering to ensure that the nose is still supported on a timber. In the process the turnout will shorten slightly. This will leave small gaps between existing templates on an existing track plan, but it won't affect the alignments. 2_232021_190000000.png Here on these overlaid 1:8 crossings you can see how a sharp nose (width=0) is aligned to the FP marker, and the timbers need to move 2mm back in order to support it. In the process the turnout becomes 2mm shorter, as can be seen from the positions of the wing and check rail ends. In addition to the above, take a couple of ...
... topic: 3610 Grouping Turnouts posted: 12 Feb 2020 00:00 from: Jason Johnson Hi all, Still learning the basics but boy, is this a great piece of kit. I have created a crossover, moved, shortened and stretched sleepers to suit where I want them, is it possible to group them together so they move as one? Been trying for hours and just cant work it out, cant see any info either so I have decided to let it beat me and ask the question. Thanks in advance, Jason.

... you can see in your diagram: 2_050731_570000000.png that Templot has closed up the spacings adjacent to the rail joints at A. The position of these joints is generally fixed by the design of the switches and V-crossings. There are special chairs for switches and V-crossings which must fit the rails at specified positions, so there isn't much scope for moving timbers to and fro within a standard turnout. But at B and C some adjustments might be needed. At these locations the rail joints can be moved if necessary by shortening the vee rails on site to fit. But that's quite a lot of work, because it also means drilling new fishbolt holes. It also means that if a later repair is needed, standard stock replacement rails won't fit. Also you can't shorten a rail by just an inch, because of the existing holes. So you have to put on your p.w. engineer's hat, and draw on your lifetime experience of track design. In this case I think I would use two separate timbers at B, so that they ...

If you actually want the adjoining track connected at somewhere other than TVJP or TXP, you would move the peg along the centre-line using CTRL+ F8 mouse action, and then use the peg and notch functions. More about them at: http://www.templot.com/martweb/gs_geometry.htm To get a better understanding of the rail ends, try shortening and then extending the template using the F4 mouse action. regards, Martin. posted: 10 Apr 2008 23:53 from: jeckardt Martin, my apologies, but pinging on this unanswered question... jeckardt wrote: For the straight turnout, I have the tie spacing correct except for the lead-in ties, J1 and J2.

... as the main road. For a curviform V-crossing it could sometimes be curving in the opposite direction. The two standard options for the radius in the splice rail section of a V-crossing are: regular or generic V-crossing: same radius and direction as the main road curviform V-crossing: same radius as the turnout road from the heel of the switch If you want some other radius in the splice rail section, as in this case (you want it to be straight), you need to shorten the turnout road exit to the minimum. To do this (change to a curviform* V-crossing and then) use the CTRL+ F12 mouse action: 2_090527_560000000.png You can then peg on your straight branch track at the shortened exit. For a siding you would need to omit the overlying sleepers from the branch track using the shove timber functions. As you will be making a diamond-crossing at this location, some tidying up of the timbers will likely be needed in any event. p.s. the above applies ...
