... EM- curves of varying radius posted: 3 Oct 2013 21:36 from: Andrew Duncan Hello Everyone I've been trying to get nice flowing curves on this plan that I'm proposing to build with a degree of success but I'm not completely happy with the result. You can see clearly the dogleg at the double junction top centre left of the plan and I am wondering if there's a recognised way of dealing with this varying type of curve in Templot 2. The track is just 2 templates so far, and I've used a transition curves in both to get to this stage. I've been wondering if I need to split up the main lines into smaller sections to have greater control as the radii changes, or will that just produce more doglegs at every join? Any advice would be gratefully received. Many thanks Andrew undefined 2787_031623_180000000.png posted: 4 Oct 2013 14:18 from: Phil O Hi Andrew I would would start a new template from about halfway between the double junction turnout and the cross over turnout and curve the template to about half way the ...
... topic: 2601 Diamond-crossing on a transition curve for Yeovil Pen-Mill posted: 22 Dec 2014 14:15 from: Andrew Duncan Hello Everyone I've been trying to get another siding (sed to store the branch line coaches)into the plan of Yeovil which has involved starting from scratch two diamonds that Martin originally did for me about a year agao now. Whilst it's true that I've come on a long long way from those early days with Templot ,to my slight frustration I couldn't re create the first of the two diamonds at the north end of the platforms(top right on the plan) that comprise the line from the down Platform across the upline to the goods shed. I've been able to create diamonds else where but none of these has been on a transition curve. Do I need to first make a turnout, get that aligned and then create a half diamond after that? Can anyone give me some pointers or tell me where I can read up on this(ideally an illustrated version as I'm not too good with ...
... enough to use as it stands. regards, Martin. posted: 8 Jun 2016 21:36 from: Martin Wynne Hi Gavin, Here is my stab at redrawing your AnyRail plan in Templot. This is just my idea of what you might do. I fully expect you to make changes and/or reject the whole thing. I made a few changes to your plan. It now contains some interesting formations to practice your trackbuilding skills. 2_081606_410000000.png I kept your preferred straight run through the platforms, but there are now transition curves at each end of the station to provide a smooth entry into the sharp end curves. The track spacing for the main station area is at the prototype 6ft way (44.67mm centres), but I increased it to 7ft way (48.67mm centres) in the sharp end curves to ensure clearance for vehicle overhangs. On the left I moved the main line crossover round into the curves to avoid a double reverse curve and increase the clear length in the platform. This has created a nice tandem turnout for the short siding ...
... ) using templot. I've played around a bit with templates and looked at a few of the tutorial videos but i've come a bit stuck with one (of many i'm sure) problem. I have two offset parallel straight sections separated by about 12". I want to join these with an s bend to form a single track and then add some turnouts along the length. My problem is joining the two sections with the s bend while maintaining the parallel straight section at the start and end of the track. I've tried transition curves (easement from straight) etc. but i always end up with a curve at the end or the straights not being parallel. I'm sure there's a simple solution, but i'm still trying to get my head around all the options and get lost so any pointers would be appreciated.

... topic: 2360 S-curve slewing posted: 14 Dec 2013 13:30 from: Godfrey Earnshaw Is there any way of controlling the parameters on this geometry.For example if I have a straight track (00-sf) and want to offset it by 50mm in a length of say 700mm with an equal curvature, S Curve Reverse Transition, are there any ways I can control this. Cheers Godders posted: 14 Dec 2013 15:31 from: wcampbell23 Hi Godfrey No doubt there are better ways of doing it- but here is my suggestion: Set up the tracks on either side of the transition. Attached a curved track to each side so that the curves are of equal radius (unless you want otherwise) and opposite hands so that they do not intersect. One curve should be stored in the background and the other the control template. Click on the template for the background curve and select the Peg/Align tools option. Select the "make transition curve from the control template" and then try the left or right hand options ...
... topic: 1281 Replacing a slew with transition curves posted: 8 Nov 2010 14:17 from: richard_t Hello I've managed to find another 1.5 meters for the fiddle yard for Manchester Windmill Street, and "permission" to route two of the lines through the camila bush rather than the one I currently thought I'd be able to do. This means that I can, eventually, have the two running lines out to the garden. I still want a siding leading to a cassette for the short term. As the siding lengths can remain the same I have more space to slew the lines from the exit of the garage door to behind the bush. I wondered if there is a simple-ish way, of converting a slew to a set of transition curves. My attempts have been a bit rubbish so far. The reason for the conversion is that I need to put some turnouts on the slew and I find this easier to do with transition curves than with slews. The distance between the tracks centers are 555.8mm and the distance I have ...

... topic: 1203 Transition curves posted: 15 Aug 2010 12:42 from: Judi R Hi, I've been trying to get my head around Templot for the past few days and scored a major victory today when I finally cottoned on to how to re-select a template previously placed onto the background without getting a duplicate on top. I have the disadvantage of having used AutoCad and similar packages beforehand, even though it was a long time ago. Now I'm trying to get to grips with transitions. I've managed to create a transition curve from a straight to a circular curve, although the "start" and "finish" were at the opposite ends to where I expected them. Now I want to create a transition curve at the other end of the circular curve back to a straight. I've read through the tutorials and watched the videos, but I can't find anything on this. I've placed a straight alongside the end of the curve and have tried to link them with a transition but Templot says it can't but won't say why. ...
... topic: 880 Transition curves posted: 26 Jun 2009 10:16 from: Howard I'm using Templot 0.91.c on Windows XP. I'm struggling to make a transition curve from a 3" straight that enters my 4' by 2' baseboard 41.5 cm from the front edge and leaves via a 3" straight 175 cm from the other end (of the 4'). Sorry about the mixed measurements! This is 2mm/N Gauge. I first make a guess at a transition curve, using something between 24" and 36" radii, but then need to adjust it. I'd prefer to do this interactively without having to re-enter all the numbers. I cannot get <Shift><CTRL><F1> or the "-" key to do anything. No little window for changing the 1st trans. radius appears, and moving the mouse just moves the whole track plan. Likewise for the 2nd trans. radius. Using the menu option "action|transition radius options" also has no effect. Perhaps there is ...
... topic: 2641 Transition Curves: posted: 2 Mar 2015 21:30 from: Andrew Duncan Hello Martin Back on 13th January you replied to my question about transition curves; When you say that you can't get make transition to work for you, what goes wrong? What do you see? If Templot can't make a transition in the desired place it's unlikely that you will be able physically to fit the tracks there. In answer to that question I've now, at last, done a screen shot of the problem that I experienced when using "Peg\ Align\ Make transition curve...". In fact I've done 2 screen shots one of the initial result as proposed by Templot and a second with my change to the curve to make it "match/ align". 2787_021620_120000000.png And this is what I modified it to... 2787_021617_010000000.png I used F6 to change the curve to this which I think looks ok, but without scanning along the curve with my eye down at track level I don't have any means of knowing if ...

Richard Attachment: attach_2370_2959_Ravensfield_7.box 253 posted: 29 Dec 2016 01:37 from: Martin Wynne Hi Richard, Welcome to Templot Club. That's very impressive for a first plan with Templot. I guess you created that by joining individual templates? I'm sure others will explain how to remove the geometric look and put the station throat on a flowing S-curve transition. You asked about how to check clearances with the dummy vehicle tool. I have made you a bit of scruffy video showing the basics. See: http://flashbackconnect.com/Default.aspx?id=5nCtH2kgd6-uvHhoWDIn4Q2 Sorry I don't have time to make a proper edited video at present. I will make another video clip shortly, showing how to fix the clearance problem. regards, Martin. posted: 29 Dec 2016 03:09 from: Martin Wynne Hi Richard, Here is the second video clip, showing ...
... two straights? posted: 8 Nov 2008 18:07 from: Richard Spratt I've watched the Curly Corner video and reproduced it successfully. But now I want to do it with two track straight tracks that already exist on the plan at a shallow angle. The best I've managed is to extend the straights until they just intersect. Trim them both 500mm. Put a curve between them. This is templates 5, 6& 7 in the attached box file. Continuing, if I then try to change the curve to a transition it is only a transition at one end. So I then half the swing angle (incidentally halving the swing angle by typing it into the box usually results in calculation failure) and mirror it on peg, but then it doesn't line up with the second straight. Templates 1 to 4. Is there an easy way to get them to line up. Or so I need to persevere with shuffling them around until they look right? Thanks Richard PS How about Martin not answering until say Monday evening? Attachment: attach_400_620_curly_curve_of_two ...

... topic: 3812 Transition links posted: 10 Nov 2020 08:06 from: Graham Long Hi I have grappling with transition links. I have sucessfully produced an easement. I how want to link a transition between to plain track templates. I.e. I want to produced a link between a 1400mm radius plain track and a 2500 plain track. I have tried to follow Martin's video but it is linking two turnout templates. Do I have to make both templates turnouts to link them and then make them plain track again after having done so? So far I have made one of the templates a turnout and split off the approach road, but I am not clear on how to make this a dummy template as described. Then you are required to make a branch line from the other template. However, I think I would have to make this a turnout template as well. Could anybody clarify this for me.

... looking for slavish prototype fidelity but I want something that looks good and feels like the real thing. This jpeg is a general overview.1588_161717_090000000.jpg The attached box file shows where I have got to so far and I would welcome comments on the templot side of things. Please note that I have not really tackled timber shoving yet on this plan. That's for later. Turnouts are B8s throughout but with C10s on the two mainline junctions. This feels right to me but I am open to other suggestions. My real question is around the transition curves. I have tried hard to get a smooth transition between the "straight" sides (though they are not really straight) and the end curves. But I seem to have ended up with several small templates, particularly on the double track branch. Probably a result of adding turnouts into the line, splitting off approach and exit the changing my mind, back to plain track, back to turnout etc. Are my transition curves OK? I really want to get a smooth mainline feel. I am happy to ...

Purely by luck I just swapped the peg position to see what would happen. Cheers Bruce ...
... topic: 3754 Turnouts in Transition Curves posted: 31 Aug 2020 22:13 from: ScottW I don't have any experience building track but I was wanting to know if it was okay to build a turnout in a transition curve? I was under the impression that turnouts should never be placed in a transition curve, so am I asking for trouble? My latest project (see Share& Show) has a number of transition curves. I was thinking of moving the entry to the turntable/engine shed further round to the right but this would mean that the turnout was in a transition curve.

... topic: 2831 Bug warning- make transition posted: 23 Jan 2016 02:21 from: Martin Wynne There is a bug in the changes which I made recently in the make transition function. In the event that an existing transition curve is zero-length, selecting the 2nd radius option fails -- the 1st radius is always used. Sorry about that, I will get it fixed. In the meantime, the workaround is to put the peg at the 2nd radius end, and select the at peg option. Zero-length transition curves are not often used, so this won't affect many. But they are sometimes useful, for example in creating a symmetrical Y-turnout with straight exits through the V-crossing: 2_222120_040000000.png regards, Martin. posted: 7 Feb 2016 17:49 from: Martion Elsworth I've been trying to find the Make Transition function but can't- where is it please?Martin Elsworth Martin Wynne wrote: There is a bug in the changes which I made recently in the make transition function.
