... affect the final result, but it can be very irritating if you are in the middle of a fine close-up adjustment. Note that such jumping doesn't happen for a custom switch, so an alternative to locking the switch is to use a custom switch on the template. Is this the case if you're zoomed in around the fine point, and the peg is on the FP? Won't the turnout size change towards the switch end? Which is roughly the case with the irregular diamonds. Also any chance of "lock transition" in the next version?

Hi Gordon, That's the famous "matchsticks and broken glass" effect. It's a known effect. Your coloured tracks make it look even more dramatic! It is caused by the transition curve being too "gentle" for the maths capability of your processor. In other words the radius changes by too little in too long a transition length. If you look at the transition radii there you will see 2053- 2020mm radii -- a difference of less than 2%. When you get this effect you can be fairly sure that you are using a transition curve unnecessarily, and that a fixed radius curve would do just as well. Sometimes this effect flashes up while doing F6 on a transition curve template ...
... topic: 3749 Gauge One garden railway using Cliff Barker track posted: 26 Aug 2020 17:14 from: Roger Bristow I am a returning Templot user, from 2005! I started a Gauge One garden railway all those years ago and now want to add a triangle from the double main line down to the steaming bay and turntable area. I remembered Templot and have now downloaded the latest version. I want to add a double line junction curving away from a curving (transitioned) main line. Forgive me if I haven't used the correct terms for what I am trying to achieve. If I could get a start on this part I think I could make good progress. Roger posted: 27 Aug 2020 06:39 from: Martin Wynne Hi Roger, Welcome back to Templot Club. If you are making a double-junction on a transition curve, you will need a transitioned diamond-crossing. There is a video showing how to create one, here: http://flashbackconnect.com/Movie.aspx?id=ib65pLfUkgNxFBDqAZSNyA2 It is 5 ...
... 17 Feb 2008 03:36 from: NGT_Models OK, here's what is no doubt a silly question, but can two or more sections be combined into one section. Reducing the total number of named pieces in a design? Say you made a curve from two or three sections, can these 3 be combined into on e piece? Thanks, Zoë the un-trained posted: 19 Feb 2008 13:19 from: Andy B As no-one else has yet responded- Yes and no! You can create a transition between 2 separate elements of constant radius (straight being a constant infinite radius), then extend the ends of your new transition to the ends of your original elements. That may reduce 2 sections to 1. If you have 2 adjacent sections of the same radius which are for some reason split, then just extend one to the end of the other and delete the 'other'. To move a group of sections of track together, use the 'Group' functions. Beyond that, all sections will be individual and have ...
... at the same time, will this be a problem? I very much doubt that you are using the adjacent tracks function, which draws the adjacent rails as part of a single template (without any timbering). You can try it by clicking the generator> generator settings> adjacent tracks menu option: 2_041550_070000000.png This function is now hardly ever used. It was provided in the early days of Templot as a design aid, but other functions have made it largely redundant. It is sometimes useful when adjusting long S-curve transitions. Almost certainly your multiple tracks have been created using separate templates with timbering. These will be entirely unaffected by these changes, and you will be able to add a platform edge alongside them. regards, Martin. posted: 5 Jul 2010 01:08 from: kenbec Hello Martin, I thought I would start a topic where I can report occasionally about what I'm currently working on in Templot.

... . posted: 8 Jul 2013 03:07 from: Martin Wynne Hi Tony, I rather doubt that the rail lines shown on the OS map should be relied on too closely. The first switch has no diverging road shown. I made the entirely arbitrary assumption that the left-most road is the main road, and that it is a common type 1 tandem (i.e. second switch in main road of first switch). The only way to match the rails as drawn is to put the whole thing on a transition S-curve, which seems a bit unlikely. I think it might be better to straighten it out and adjust the turnout on the right accordingly but that is up to you. Here's a quick stab at it on the S-curve. It needs some further splitting out of partial templates, but there is no point in my doing any more on it or posting the box file until you provide the scaled image -- I simply scaled it by eye: 2_072132_220000000.png It looks a bit odd, but I think ...
108. Single slips
... preparing a reply! Hi Trevor, You have used standard switches instead of the preset slip switches: 2_300644_220000000.png Also one of your switches is a 9ft switch, which is unnecessarily short for a 1:7.25 slip. If you use the preset slip switches and peg them on to the TCP and MCP positions, the blade tips will be correctly supported on the timbers and clear of the check rails. (At present you have them in fresh air, and one opening behind the check rail): 2_300700_410000000.png Also you have long transition zones running through the slip switches, which tends to be unnecessary and confusing. I am not sure what you mean by extra lines? Do you mean the track centres lines for each partial template? They can be turned off in the geometry menu. regards, Martin. posted: 30 Jul 2014 13:59 from: Trevor Walling Hello Martin, Sorry about moving it while you where doing the reply.

... black one to mark its vertical position for the current control template. See also: topic 1091 pad_symbols.png regards, Martin. posted: 14 Jul 2012 21:58 from: dave turner Martin Thank you for the explanation. For many years I was an AutoCad so-called expert user and lisp programmer. So I still find some of the Templot fundamentals non-intuitive even though I do understand the reasoning behind them once explained to me. Just as an example one of the issues that reappears is the inability to create a transition between two templates that intersect when projected. Simpler programs such as XTrkCad are able to do this and allow the mouse to adjust for the "curve". I find myself using this program to generate the overall view then using it as a background to create the detail in Templot. Please note I'm commenting not complaining about this as I assume that it's a fundamental difference in philosophy. regards Dave posted: 14 Jul 2012 23:00 from: Martin Wynne dave turner wrote: Just as an example one of the issues ...

The errors are of course minor and immaterial in the main, but is there any logic to what is causing the issue?

... the best result. Depending on the position of the boundary between the two turnout templates, the return curve may be too short (needing an extra short bit of curved double track to reach the straight section), or too long, in which case it won't fit. Another option would be to change to a parallel type V-crossing on the lower turnout, but with the same problem if the return is too long to fit. Difficult to say from your screenshot. A better solution is probably to use the make transition function: 1. make MS double track from the upper turnout template. Extend its length. 2. make branch track on the lower turnout template: 2_061431_460000000.png 3. Using F6, curve it round so that the two centre-lines don't quite cross: 2_061433_570000000.png 4. click on the background template (the straight track) and then peg/align tools> make transition curve from control template. This will be the result: 2_061437_050000000.png 5. now delete the two underlying templates. Then click on the lower turnout and ...
... topic: 1621 F6 Curving- S Transition Curve posted: 7 Sep 2011 08:59 from: its_all_downhill Hi Martin, Think I might have found a minor bug with curving with a Transition S curve. On trying to change the 2nd (2R) radius curve the movement which normally is a click and drag operation now has changed to a click, move cursor (with no visual change) and click again to make the change. It works fine with the 1R radius option and switching back to 1R radius clears it until you select the 2R a second time. I am running Templot on a Virtualbox VM on Mac OS 10.7 and did not experience this in previous dev version, I think.. I could take a screen recording mut I don't think I can upload mov files?

It is still very much as it was when originally split from Templot2 18 months ago. So there is ...
... remain in force* for subsequent adjustments to the control template but don't change any previously stored templates. However there are several "modify on rebuild" functions to make various aspects of the stored templates match the current control template. You will find these as modify group to match menu items. *if you mint a NEW control template, some settings are restored to the REA defaults. Last, the track plan I am following has a gradually tightening curve. How can I persuade Templot to do this? Click the geometry> transition curve> C-curve shrinking transition menu item. More about that at: http://templot.com/martweb/gs_geometry.htm#transition To fit a transition curve between existing templates you need the "make transition" functions. More about that here: http://templot.com/martweb/info_files/make_trans.htm and it is also covered in many of the videos. regards, Martin. posted: 4 Nov 2014 21:32 from: Richard Spratt CPM wrote: I have jumped in at the deep end and maybe ...
... suggest: 1. on the loop turnout put the peg on CTRL-0. 2. change it to a regular crossing. 3. change the crossing angle to 1:7.5 4. such turnouts usually look better with equalized timbering. 5. on the goods yard turnout, change the crossing angle to 1:7.5 6. use the CTRL+ F12 mouse action on it to extend the turnout road to fill the gap: 2_181146_140000000.png The design could be improved for a better "flow" into the platforms by using transition curves. You would need catch/trap points on the exit from the goods yard onto a passenger line. regards, Martin. posted: 18 Nov 2017 17:47 from: Michael Henfrey Thanks Martin, It looks better now for sure..

... branch track off to the left then there's no engineering reason why this would be a curviform right hand turnout? Hi Paul, Sorry I didn't quite follow that. If the branch track is to the left, then it's a LEFT-hand turnout in all circumstances. Otherwise the switch deflection would be in the wrong road with a corresponding speed restriction in the running line. If you want a change of radius in the main road within a single template, the way to do that would be to use a zero-length transition curve at the location of the change: geometry> transition curve> zero-length instant transition at peg. Set a normal transition first. Then instead of roaming, use SHIFT+ F9 slide or CTRL+ F5 orbit to take the transition with you. See video at: topic 871 cheers, Martin. posted: 2 May 2020 14:01 from: Judi R Paul, the hand of the turnout is defined by the set of the switches and the turnout road is subject to the speed restriction that Martin refers ...

There is a new section showing how to use partial templates to get a more accurate match to the underlying transition, and I have added a few more notes.

118. Checkrail on curves
... topic: 2580 Checkrail on curves posted: 24 Nov 2014 20:40 from: DerekStuart Me again... A question (or 3) for the experts- of which there are plenty here! Checkrails on curved track- 10 chains A) Assuming you are coming from a straight section (very low speed so no transition curve (or should there still be one anyway?)) how far should the checkrail lead in from the straight, or does that depend upon speed rating of road? B) I have just read that the checkrail sits proud of the running rail, but I am not 100% sure this was for British track. Is this correct and if so, how far does it sit proud? C) In model form, C&L Exactoscale says to use standard chairs and on each sleeper, alternating between running rail and check rail, with a decorative half stuck on in the appropriate places (I have plenty of 'halves', given how many I've broken!). I wonder if this is the ...

... ! Best wishes, Bob Ellis posted: posted: 16 May 2007 23:16 from: Richard Spratt I for one find Templot not too difficult. I've only owned a copy for 2 months and have produced the track plan for our area group's new (first) layout. Ok it only has 6 turnouts, but they have changed as the design progressed, and at one point there was a tandem in the middle of them. The biggest problem was when I tried to trace some OS maps for my own layout using transition curves. I couldn't get them to match with those on the map. Then Martin pointed out that the curves on the map have a kink, so no wonder I was struggling. Regards Richard Spratt PS Bob we might run a Templot day in the AG sometime.

... topic: 2687 Scissors crossing on transition curves posted: 14 May 2015 00:01 from: dave turner This is my attempt to create a scissors crossing between two transient curves at the approach to a station. (Shrewsbury circa 1955) With the lack of actual data I've assumed GWR curved turnouts. The attached box file is my best attempt so far. Over and above any other issues that I've probably screwed up, I would like advice/comment as well on two further points. a) I extended the top check rail over the full width of the crossover while leaving the bottom check rails split. On further consideration if this were to be done perhaps the inner (bottom) curve, if any. would have the extended check rail. What is the best way? b) The Right Diamond is as it was generated by Templot whereas I attempted to extend the Left Diamond checkrails to meet and form a 'point' which I wasn't able to do. 1) is the Right Diamond, as is, adequate for safe operation? ...
