... menu item. (For this method this setting is optional.) Click the tools> make diamond-crossing menu item. If the angles differ, the result will be an irregular diamond crossing. If the angles are the same, the result will be a regular diamond-crossing. Method 2. Start with a turnout having a curviform V-crossing. Click the tools> make ladder crossover> make curviform ladder menu item. Click it again a few more times. The above two methods can cope with having a transition curve in the main road, although you will probably need to follow up with some adjustments to the transition zone to get the desired result. Method 3. Start with two lengths of curved plain track crossing over each other, or one curved and one straight length. One should be a background template and the other the control template. Click on the background template. On its menu, click peg/align tools> make diamond-crossing at intersection menu item. Follow the instructions and wait a moment while Templot does ...
... all over the place. I haven't got the hang of how to manipulate it better for clarity. My answers to you questions are in bold or in separate boxes. I hope this time the box file will come through ok Andrew Attachment: attach_2104_2665_Yeovil-Tunnel-entrance-curves-sorted.box 225 posted: 8 Apr 2015 00:29 from: Martin Wynne Hi Andrew, Thanks for the .box file. The problem is template TR3822, no. 231 in the storage box. You have hit a known issue, where the transition curve is too "gentle", i.e. the change in radius is too small over a transition zone too long. This causes the transition calculations to exceed the maths capabilities of the computer processor. Templot tries to catch this condition, but isn't very good at it. When I have tried to make it more secure, it restricts the usable functionality by too much. Usually it displays as a shattered glass effect, see: topic 1391 The effect on your template is rather more dramatic, drawing rail edge lines several ...

You can improve it significantly by changing to a C-9.5 with a curviform type of V-crossing. This increases the smallest rad to 1180mm: 2_151729_030000000.png That turnout was a bit too long for the existing template, so I merged it with the approach straight track to create a single transition template as easement from straight. I reduced it to a zero-length transition, and adjusted the transition markers to coincide with the previous template boundary. The C-9.5 turnout could then be roamed into position (CTRL+ F9 mouse action) until the exit aligned with the existing track. .box file attached below. regards, Martin.

I think you are paying a lot for the idea since the construction of the instrument doesn't warrant that price. Jim. posted: 24 Sep 2017 08:57 from: polybear Interesting idea, and useful for flexitrack users. But presumably not a true transition curve? As for price, I was expecting maybe £40 or so. But £195? That's just nuts. I don't expect many will appear at that price, for what is after all a piece of (I suspect) laser cut stainless with a few tapped holes and securing screws.

Anything you can add to your previous advice would be most welcome.

It looks to be an excellent project, and an ideal plan for 00-SF. There were some misalignments and several unnormalized transitions, so I have taken the liberty of re-working the right-hand part of your plan.

... . If you are planning a large layout and need irregular diamonds, I suggest leaving the design as crossed plain tracks in the meantime. By the time you need the full template for track building, the required functions may be available in Templot. I discussed this at greater length with a preview screenshot at: topic 18 If you need a full irregular diamond template right now, it is possible to do it using multiple partial templates. Here is an example of such a double junction containing an irregular diamond-crossing on a transition curve: http://www.templot.com/samples/irreg_double_junct.box (Right-click and Save As...) To see how it is made up, hold down the Shift key or put the Caps Lock on, and then run your mouse over the template name labels.

... turnout side,and it won't let me, because of the Vee I've used. can anyone give me a shove in the right direction? Ta! 3033_101604_080000000.png posted: 10 Oct 2015 21:34 from: Martin Wynne Hi, The parallel type of V-crossing is a bit of a legacy from years ago and not much used nowadays. As you can see it is limited in what you can do with it. I have left it in Templot because it can be very useful where you have a turnout in a transition curve (make return curve isn't available for transitions). Try this: 1. change to a regular type V-crossing. (You can now in 212a click the green indicator at the top left of the trackpad until it changes to R.) 2. click tools> make branch track menu item. 3. curve it to your desired alignment (F6 mouse action). 4. insert turnout in it: template> insert turnout in plain track menu item. In your case followed by 5. template ...
... 1. using the dummy vehicle set the required clearance. For this purpose I set 36.5 inches clearance each side of the default vehicle dimensions (9ft-3in wide) (111 inches). This makes a clearance on each side of 7ft-8in (92 inches) from the track centre-line (on straight track), matching the prototype minimum structure clearance. 2. run the dummy vehicle along the tracks, leaving a trail of dummy vehicle copies. Do this only on the constant radius sections, not within transition zones. Allow a bogie pin to run over a template boundary only if the radius is unchanged across the boundary onto the next template. 3. use the mouse action to adjust the adjacent track centres to align to the extent of the dummy vehicle copies. (This mouse action was introduced in 213a.) 4. do tools> make double-track to create a dummy track template along this line. For constant radius curves this is the clearance line. 5. if the curve includes transitions, do make transition ...

... topic: 3655 Saunderton posted: 2 May 2020 22:44 from: David Gwynne With some swearing, some frustration but with the software sort of clicking with me a few times, my first effort attached. Any feedback gratefully received. In particular, I struggled to join two of the turnouts together with a plain piece of track (just above the diamond). Suspect I may also need to learn how to transition between pieces better. Not sure if it's possible to exactly follow the lines on the 6" maps but I've tried to keep as close as possible.

... nowhere! It works fine of course if the whole crossover fits within the double track section length. I suspect my method of splitting up the plain track into short lengths is flawed but I am at a loss to see a better way so far. Sorry if the above description isn't the best thought out one. Anybody ?? Rob posted: 18 Apr 2011 10:49 from: JFS Hi Rob, It goes wrong of course for exactly the reason you suggest!! You need to join your "bits" with transition curves, then delete the original "bits" That way you end up with one continuous length of track with compound curves. (see Martin's transition curve video). If you insert a turnout into that, it can be roamed along then whole length. Beware that when you make it into a crossover, the alignment of the newly created second track will only be approximate (Templot warns about that) so it is best to increase spacings above the minimum to avoid any restricted clearances between the double tracks. Martin has ...
... : 2969 214a changes- extend/shorten to meet posted: 25 Jan 2017 03:47 from: Martin Wynne Dear all, If you have run Templot in the last few days you will know that there is a new program update 214a available. No need to provide a link- Templot will download it for you. There are several new features in 214a, but for established users the most useful will probably be the new extend/shorten the control template to meet function. I created this mainly to make the make transition function less tedious to use, but I have since found it very handy in other cases too. It is no longer necessary to swap peg ends and carefully adjust manually the new transition template length to the required template boundaries. Templot can now do it for you. The ancient make transition tutorial can now be deleted, and replaced with this new one at: http://templot.com/companion/link_existing.html which explains both functions. For this tutorial I have reverted to a static text tutorial with screenshots, instead of ...
... Jubilee42 Dear all After making a lot of progress with Templot and track building in the Autumn, the rest of life got in the way, and although I have tried to get back to track planning it's been in fits and starts, and I forgotten a lot of what I had learnt. In short, I've got stuck and rather fed up. I'm trying to draw a single slip. However, I can get the roads drawn properly to get to the crossover part. I always end up with the crossover on a transition curve, and then Templot throws up warnings. The video on making the slip part seems fairly easy to follow, but I need to get past the crossover bit to get there. I'd be grateful for any advice!

... K&L /C &L components and their flexible track but although it is an improvement on typical RTR track, the sleepers are still too long (relative to the gauge) to my eye and I like the idea of EM as being a suitable compromise as I feel that it could theoretically be a regauged version of OO with improved flangeways and appearance. I appreciate that this is quite a simplistic view but I was hoping for the dockyard branch I would be able to get track nearer to 20" radius (with transition curves) and very tight radius points on the quayside. The line will be operated by small tank locos, (Webb 0-4 -2T, L&Y Pug, possibly an 08 shunter depending on what period I am modelling) so hoped that these would run well even down to tight radii such as 20" (with check rail). Similarly, for the main point work in the passenger and goods area, I was considering A4 or A5 turnouts as it will all be low speed terminal station operation ...
... too. At the moment that turnout would give you quite a severe reverse curve. ** DISCLAIMER** I know nothing about anything. posted: 16 Apr 2017 12:23 from: Martin Wynne Hi Panos, 1. Try starting with the turnout on the left, set curviform and the TS spacing, and then tools> make branch crossover. You can then extend the turnout to a longer size (to increase the inner radius) with F5 mouse action, and link it to the existing curve using the make transition function. 2. Alternatively, curviform then tools> make branch track, adjust the radius to tangency (by eye) with the existing curve using F6 mouse action, and then insert a turnout into the curves at the intersection. There is a page about how to do that at: http://templot.com/vis_box/turnout_on_intersect/ Also at: http://templot.com/companion/fit_turnout_to_existing_curves.htm l That page is in an experimental format which I didn't use again, sorry if it is all a bit confusing ...
175. Curved Diamond
... I don't want to change any of the existing alignments, as I struggled for a long time to get the whole thing to flow. Ignore the timbering -- I'll be using interlaced sleepering a la Caledonian Railway. Can anyone advise me? Please! Allan Ferguson Attachment: attach_746_1061_Muckhart_north_10 _03_07_0124_09.box 318 posted: 7 Mar 2010 08:48 from: Martin Wynne Hi Allan, It's not generally a good idea to run a slew through pointwork -- slews are intended mainly for plain track. If possible it is better to use a transition curve instead. I found that this transition matched your alignment very closely: initial radius= 10980 mm final radius= straight length along the initial radius= 0 length along transition section= 995 mm 2_070316_330000000.png I snaked (CTRL+ F6) the turnout forward by about 2mm to line up the V-crossing with your existing track: 2_070317_110000000.png The diamond-crossing is an irregular diamond, meaning that the radii in the two roads differ. This means that all the crossing angles also differ. Irregular diamonds are not (yet ...

Tony. posted: 12 Sep 2017 10:18 from: John Palmer I have also had a go at the tandem and managed to ease the curvature so that I don't think any part of this formation has a curvature less than 59" in radius. Won't guarantee that I have successfully preserved all the alignments of adjacent track (in any case all the exits from the tandem have been transitioned), but there has been no substantial change to such alignments. There's also a bit of timber shoving still required. I have also inserted two traps into turnout TL 762. The stretchers on these would, no doubt, be operated by the same rodding connection as that driving TL 535.

178. Curved Layouts
... , I always insert turnouts in plain track as this gives a much better flow to the switch and crossing work, otherwise your pretty well back to using propriety track with fixed turnouts. Cheers Phil posted: 18 Dec 2013 19:46 from: LSWRArt I have designed a station entirely on a curve as I am modelling in 0 gauge and have an overall length of only 5m. i roughly plotted where I wanted the track to go, then laid long lengths of plain track over this rough design. I also added some transition curves to soften some of the curves, so hopefully they almost disappears in the centre of the layout and are tightest farthest from your centre of interest. I then inserted points into the plain track. if you want several points in the same length of track, just Main> Store and background to make a duplicate (two identical pieces of track on top of each other).

... make changes to the shortcuts lightly, but this one was forced by the introduction of the irregular diamonds. 1. Put the notch on the rail intersection for the middle vee in the usual way. I intentionally wrote that way to deter beginners from trying 3-way tandem turnouts until they are well-versed in Templot. Tandem turnouts are not simple -- it really would be better to leave them until later. At the very least please try a single slip first. If you watch the first few minutes of the transition-diamond video you will see how to put the fixing peg on a rail intersection. The video is at help> watch a video> Scruff Video Andrew transition diamond menu item. Note that for the tandem you need the peg on the rail-edge, not the track centre-line -- geometry> peg on line or rail> menu options.

All the best Derek posted: 9 Dec 2020 21:34 from: DerekStuart PS Rather than ask this on your RMW thread and confuse some... You (and other experts) have taught us to make a nice and smooth running turnout, where you cannot feel the transition from crossing/ knuckle/ wing. Yet you can most definitely feel it on the prototype. Of course I'm familiar with the issue of scaled mass, but what exactly causes that jolt/ sound?
