... topic: 2768 new symmetrical Y-turnouts posted: 29 Oct 2015 00:58 from: Martin Wynne Two requests in one day about Y-turnouts means "something must be done". Full adjustable split-deflection switches have been on my NOD list (" nice one day") for over 20 years. Without getting any closer. But in a couple of hours today I have come up with a stop-gap solution which works far better than I dared hope. Which means I am now kicking myself for not doing something like this much sooner. It does rely on the irregular half-diamonds, so wouldn't have been possible before Templot2. I have added a new peg position at peg on split deflection: 2_281934_280000000.png This puts the peg on the TP switch toe position (CTRL-2) but at half the switch deflection angle. Which makes it easy to peg an irregular half-diamond onto a bit of plain track to create a switch front. The result is that I was able to create this with just a ...
... 2015 18:31 from: Martin Wynne For the next program update I have added a few more basic shape items on the sketchboard: square, triangle, arc, ring, segment, are new: 2_011318_400000001.png These provide a bit more flexibility in creating symbols and custom combined items. For example the ring will be useful for goods line signal arms on signal box diagrams. They can all be resized, stretched and rotated as before. And can be outlines, infill, or both, in any colours you wish, with adjustable transparency. For the arc and ring, the inner radius can be set as a% of the outer radius. Setting zero for this produces a full arc sector -- useful for coloured pie diagrams. 2_011318_400000000.png In the next program update. regards, Martin. posted: 7 Apr 2015 19:50 from: Andrew Duncan Martin A couple of small questions 1.

... rails for the middle crossing. I think the first turnout as a curviform B-8 may be a better fit to the location: 2_160731_560000001.png 2_160731_560000000.png Note that there are only 3 base templates and peg positions. It's not usually necessary to have multiple pegs in lots of different places. Just create the partial templates as duplicates of the basic 3 templates, with the various rails turned on and off, blanked or extended to length as required. This design uses a gaunt turnout for the middle crossing and the mouse action check rail adjustments, so it is for TDV only and won't work in 091c. File attached below. I have left the timber shoving as an exercise for the reader. regards, Martin.

225. Y-turnouts
... deflection switch, which are not (yet) supported on Templot. You can improvise a symmetrical Y-turnout by various means, or create one using partial templates. There is a tutorial about all this here (sorry it is a bit out of date): http://templot.com/martweb/y_symm.htm Be sure to read the update here: topic 603- message 3398 before trying the tutorial. I'm intending to add some new functions on the shove timbers dialog to set all timbers to the same angle, and adjust the angle by mouse action. In the next program update (if I can find room for yet more buttons). regards, Martin. posted: 28 Oct 2015 16:57 from: allan roy Hi Martin, Thanks for the info. I'll have a go.

I forgot to mention that now in Templot2 a convenient way to represent a symmetrical Y-turnout is to use an irregular half-diamond ...
226. WDLR Turnouts
... I can whip it up in my cad program in about 5 minutes so it is obvious I am missing something vital in Templot to do the same. This in in O14 and I have looked at John Clutterbuck's templates as a start figuring that would be a good place to begin but can not figure out how to change it. I know there has to be an easy way to do it. posted: 15 Jan 2012 20:17 from: Martin Wynne Hi Bruce, Set the V-crossing to curviform pattern. Adjust the V-crossing angle until the external geometrical radius (substitution radius) matches the required radius. There is a video showing how to do this at: http://www.templot.com/martweb/videos/subs_rad.exe If you are using TDV, use F9 rather than F5 to adjust the V-crossing angle. For narrow-gauge, light railways and industrial you could change to a gaunt turnout and set the gaunt offset to zero. This will cause the switch rails (points) to follow the geometrical radius exactly ...

... 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). Hi Adrian, Do you mean the new template is too long, or the transition 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: ...
228. Sleepers and timbers
... radius which is 5.28 metres or 17.32 ft in 4mm/ft scale, a large radius to most modellers. 28 sleepers are used with continuous welded rail (Flat Bottom) and are generally concrete. To get back to your pointwork question, the spacing of the timbers around the Crossing and Switch areas of turnous are fixed by the special chairs/ Base plates required for that particular unit and are with few exceptions set at 2'6". These standard spacings are all preprogrammed into templot and should not altered. It is permissable to adjust the angle of the timber and the length, but not the spacing where the special chairs are positioned. See the Templot companion under prototype track> MISC you will find a list of Crossing angles and how many special chairs are required for for each angle. Outside of these and the switch chairs it is possible to make quite significant adjustments. For a double junction certainly in BR days it was often although not invariably the case that long timbers would be used to span both roads whether they be at 90 degrees to the ...
... so that your replacement turnout will align correctly with other tracks. If you go to template>V -crossing settings and select "other", then enter k10 this tells Templot to create a V-crossing with an angle of 10 degrees. Probably also appropriate to use an A switch; so what you should have now will be an A-5.67 turnout, and the info box tells me this has a turnout radius of 19.4". If, for whatever reason, 20" has some particular importance then you can adjust the radius by altering the length of the entry-straight SHIFT-F11- if you watch the info box you can see the "smallest radius" changing as you move the mouse. If you really do need exactly 20" (i.e. 19.9 or 20.1 won't do) then you can enter the figure directly in template>V -crossing settings by checking the "fixed at" box in the bottom right corner of that window. I'm far from being an expert on Templot but I think all of the above ...
230. F7 snapping
... to snap templates together. But there are then much better ways of doing it than F7 snapping, with far more options, and total control over what's happening. For example here I have shortened the turnout-road exit almost to the bare minimum, so that the branch track can start curving more severely as soon as possible. The branch track template can be snapped onto the turnout template like this, after clicking on the turnout: 2_191845_420000001.png With the result: 2_191845_420000000.png waiting now for some timber shoving and possibly some further curving adjustment. regards, Martin. posted: 20 Sep 2017 10:19 from: Andrew Duncan Oh lord Martin the last thing I wanted to do is either to shock you or make you feel that you've failed Templot users because that is not what I meant to say, or imply, in the least.

... With 0.92mm rail it is possible for the check gauge to go as low as 15.16mm if the rail is left loose in the slots and the gauge tool is on the limits. Experienced users will know to pack the slots with aluminium cooking foil to get a good fit in the gauge tool for maximum accuracy. Unfortunately batches of rail vary, so this is unavoidable with fixed-slot gauge tools usable on any batch of rail. If you are making your own gauge tool, you could make a spring-loaded self-adjusting design instead. The finished check gauge should not be less than 15.2mm on the track. From the drawing you should be able to derive plain 16.2mm roller track gauge tools quite easily. As far as I know, only Brian has the 3-point gauge tool drawing. The tool diameter should be as small as convenient. Ideally it should fit between adjacent timbers, allowing soldering to take place on both sides. If you are planning constructing complex formations, it is worth milling flats on each side for better access. ...
... the turnout which was there when you did convert turnout to plain track. It may have had any type of V-crossing. This can sometimes catch you out. It's easy to see from the template which type of V-crossing is present: regular= turnout curve end marker is not at the FP intersection (marker is at CESP peg position) generic= turnout curve end marker is at the FP intersection curviform= no turnout curve end marker shown 2_271750_430000000.png For regular V-crossings the position of the marker can be adjusted using SHIFT+ F11 mouse action. This changes the lead length of the turnout without changing the crossing angle, which can be useful in some situations. My instincts tell me that at some point a "curviform" V crossing would be more suitable. So my question is "when and why" would I use a "curviform" crossing? When the track geometry requires that the turnout curve continues beyond the V-crossing. That might be: in some double-junctions in curviform ladders in yards and sidings where ...
... in colour or black and white. The cess would not extend into the area to which you refer anyway. The timber and rail positions of relevance are still usable despite the blank area. There will probably be some technical reason Martin has ignored it possibly? posted: 15 Jul 2017 01:15 from: Martin Wynne Hi Richard, Firstly of course it makes no sense for the cess to overlap adjacent templates. I am currently working on a new function to make the start position and length of the cess and trackbed edges adjustable in the the same way as for the platforms. This was suggested by Phil O recently. But thanks for reporting this. You didn't say why you are using black& white, or on what type of printer? The easiest short-term fix is to set output> output drawing options> rail infill style> none menu option. That in itself is an anomaly -- the cess isn't rail so shouldn't be affected by the rail settings. I will fix this in the next program update.* An alternative ...
234. A user gives up
... the old version of Templot and so I would spend half an hour trying to find something that the website was saying, only to find out later it had been renamed or doesn't exist any more. That said, your pointing me at "gentle geometry" page, has at least got me to understand the peg a little bit better, I can move it with ctrl+ 0-9, tho some of those numbers appear to make it disappear. But even that page details things that have changed, such as "adjust> set peg options". I have now found that (more by luck than judgement) under "geometry -> peg positions" tho even then I have a list of acronyms for the peg positions, which to a novice, make very little sense... Thanks J posted: 9 Oct 2013 13:04 from: Ian Allen Julia, Stick at it. You are obviously intelligent enough to be able decipher it's operation.

... . There is a much easier way to get what you want: 1. CTRL-0 to put the peg on the track centre-line if not already, or geometry> peg on line or rail> on main road centre line menu item. 2. CTRL+ F8 mouse action to move the peg along to where you want it. 3. geometry> transition curve> easement from straight menu item. 4. geometry> transition curve> zero-length instant transition at peg menu item. You can then adjust the radius to whatever you want (F6 mouse action, click the triangle symbol to swap 1st or 2nd radius adjustment). Note that doing this only makes sense if you want to have a turnout spanning the boundary. For plain track most users would simply have two templates, one straight and one curved. You can snap them together using F7 mouse action, you don't need to use the peg and notch. Having said that, if this is a running line it's better to have a proper transition easement template between ...
236. First try
... road, are very tight for space on the right-hand side of the diamond. However, as I say, I came up with this. Now the switch on the right of the diamond is similar to what you have used, i.e. a GWR 'B' type switch. However, to get the slip road to flow nicely, I changed the switch on the left to a GWR 'C', which allowed the slip road to blend in without a 'kink' at the end of the planning. I have adjusted the length of the two diamond check rails to in clued the 2nd Vee in each case. I also shortened the wing rail tips of the second Vee's on one side only to give more clearance to the running rail of the diamond. I have colour marked and highlighted in RED, the switches and slip road and Vee's I have added. As you will see, the slip road rails just clear all the wing and check rails of the diamond. There is still some tidying up to do, i.e. linking in ...
... the sleepers either side of the fishplate seem consistently closer to one another than a respective distance from centres of 2' 5" and 2' 2" would suggest. Last edited on 31 Dec 2012 18:19 by Bob Ellis posted: 1 Jan 2013 13:57 from: Judi R It seems that local practice varies considerably. On the track-laying that I have overseen, the PW Supervisor marked the sleeper positions on the rail head with chalk prior to clipping up. There would, of course, be some adjustments (shoving) when closing up to existing trackwork. Judi R posted: 1 Jan 2013 14:11 from: Phil O When I have been involved in removing track to replace ballast and sleepers, when relaying we used the marks left by the chairs on the rail to roughly replace the new sleepers, never measured anything, even timbering under S& C we used the old marks a bit of shoving was sometimes required to get the chairing on the timbers but that was all. I should mention that this is on ...
... Martin Wynne Andrew Duncan wrote: I wonder if you could either tell how to draw outlines of baseboards etc on my plan, or where I should look to understand how to do it. Hi Andrew, There are at least 5 different ways to do this. 1. If you want the baseboard outlines to be part of the .box file, you can create them as dummy track templates. Simply set geometry> track centre-lines only for plain track templates. You can then use all the usual mouse actions and template adjustments to create whatever straight or curved baseboard outlines you want, including curved edges following the tracks, etc. For open-top baseboard construction, you can have cutting lines for the trackbed edges shown on the trackpad by clicking the geometry> add trackbed edge menu items. 2. The original intended way is to use the background shapes functions. Click the main> background shapes menu item. You can add rectangles, lines and other shapes in two ways: by first clicking 2 corner locations on the trackpad, or by ...
... regular diamond-crossing.____ For all irregular diamonds you will probably want to do some timber shoving to tidy them up. The program needs some further work in this area. Note that the DP peg position (CTRL-3) for an irregular half-diamond is not coincident with central CTRL-0 position and serves little practical purpose. Or at least, I haven't found a use for it yet. *There is in fact a way of working with transition curves, but it requires several additional adjustments so not really for beginners. regards, Martin. posted: 22 Jan 2013 22:26 from: Rob Manchester Mike, A switched crossing is usually called a single or double slip. Based on a diamond crossing but with the addition of pairs of switch rails to allow routing other than straight over the diamond. If both routes have the option of being switched it is a double slip, if only one of them then it is a single slip. There are tutorials on building them if you search this site. ...
... 2012 01:47 from: Martin Wynne PeterD wrote Before developing this further, I want to create crossings at the intersection of the overlaid track (3 -off). I seem to recall a description as to how this can be achieved on the website. Alas, I cannot find it. Please can you help? Hi Peter, Use method 3 described here: topic 2080 One of your crossings looks to be getting close to the shortest Templot can do, 1:1.5 In which case you may perhaps want to adjust the tracks a little. The above method in its basic form as given there applies only to straights and constant radius curves. It looks that some of your crossings will be on transition curves. That requires a bit more work, although not too difficult. I will try to get a tutorial done soon -- I seem to be saying that a lot lately. At present I'm a bit too busy with coding for the next update. regards, Martin. posted: 26 Oct 2012 06:17 from: PeterD ...
