... when this mouse action starts. In the video the template alignment is in a separate background template so that you can see what is happening. That is not usually the case of course. The slide through peg mouse action moves the fixing peg along its current centre-line and shifts/rotates the template on the trackpad to keep the fixing peg fixed in position on the trackpad. The template alignment shifts with the template. If the peg is on the main-road centre-line and the template is not on a transition curve or slewed, these two mouse actions are very similar in end result. Otherwise they produce different results as you can see in the video. In practice, snake tends to be used much more often than slide. Note in the video that although the red fixing peg appears to get "left behind" it is still part of the control template. Each template has its own fixing peg, which can be anywhere -- it doesn't have to be within its boundary. If my explanations above are impenetrable, sorry ...
... topic: 2792 Irregular Diamonds and Making Transition posted: 26 Nov 2015 10:58 from: grob1234 Hi Martin, OK, so I understand from the brief RMW chat that for an irregualr crossing, I have to join the tracks up manually. So here is what I did: templot%20q2.png Which became this, after I erased the underlying tracks: templot%20q3.png OK, fine! But the timbering on the crossing looks 'weird'. How can I sort that out? Also, would the same principles apply if I wanted to create an irregular single/double slip within existing crossing plain track? I have watched the video on making slips and I think I just about have it, although thats for making ladder style crossings. My track plan seems to just have random slips all over the place, hence the need for the irregular ones. Hope my words make sense! Many thanksTom posted: 26 Nov 2015 16:27 from: Martin Wynne Hi Tom, Welcome to Templot Club. Instead of explaining in words, I have ...
... Platform 3 (the former down through platform); Platform 2 (the former up through platform); and Platform 1 (a bay platform). Starting at Platform 3 on the right, I need the toe end of the turnout to cross the baseboard joint at 90 degrees and since I am using pre-assembled common crossings from C&L (which are straight), I think this turnout is 'final'. If I reduce the radius any further then the diverging radius drops below 36 inches and I have a transition of zero length between this curve and the common crossing. I have then made an ordinary crossover at 44.67mm centres, which should provide the access to Platform 2. I'm not sure why it stops short of the baseboard edge at 980mm, but it's not critical as this will be flexi-track. Jumping to the mainline from the fiddle yard (ie on the left), I have fitted a short straight and then a constant radius curve to the common crossing and again a straight through the common crossing. However, ...
... . Templot has all the tools you need to create proper rail joints and sleeper spacings for short rails, and to flow the spacings across the template boundaries from one template to the next. But it's a lot to explain, and years since I last did so, so I will make some new video clips shortly. Also it hardly belongs in the "baffled beginners" section, so I will move this topic to "Templot talk". You can have two different radii in a single template if you make it a transition curve template. If you want an instantaneous change of radius, you would set the transition zone length between the two radii to zero. More about all that at: http://templot.com/companion/transition_curves.php Zero-length transitions are sometimes useful for turnouts, but for plain track it is generally better to use two separate templates. There are pros and cons -- a zero-length transition template doesn't need any further work on the sleepers and rail joints. But several of the design functions in Templot are ...
... amount. Then a slight F4 adjustment to fill the gap (for a perfect result you should really adjust both templates to the mid-point of the gap). You could instead slew the inner road, or slew both by half the amount. But it's generally better to leave the tighter radius undisturbed and modify only the easier one. I could do a bit of Jing video? A 90-degree curve between straights has a bit of a train-set look to it. At the very least you need some transitions, and ideally not exactly 90 degrees. regards, Martin. posted: 7 Apr 2009 16:09 from: Andy G Hi Martin, I'll give that a try. To be honest the example I gave was simplified to avoid confusion, we are using transitions though at one end of the layout the track does bend through 90 degrees over a distance of about five feet- compromise of building a roundy round in a limited space, and this is the end Jim Summers keeps using a photo of! Photos of the ...
... topic: 1192 Can't get transition to straight/from straight to work during one of track plan tutorial posted: posted: 10 Aug 2010 10:07 from: grog_polymer Ho all, I am doing the "Track Plan Tutorial" in 0.91c. Some of the shortcut keys don't seem to work as described but I expect that to be a version specific thing. Indeed shortcuts are only shortcuts if you can remember them. It does take a while looking for where things are in menus etc though. This specific issue: I had added the works siding by adding a branch track from the loop to works siding. I have tried to make a transition to straight to make the end of the works siding straight. No matter which end I put the peg the straight always ends up at the turnout. The notch is there and I suspect that is why. I have tried adding the transition and doing end for end etc but nothing makes it right. Picture attached.1920_100452_420000000.png There are a couple of other things that I am not clear on. I ...
... topic: 308 Bug warning -- transition adjustments in roll-out mode posted: 13 Jan 2008 05:11 from: Martin Wynne Dear all, It's not often I report a fatal bug in Templot, but I have just found one, so please steer clear of it. If you change to the seldom-used action> transition zone options> transition fixed (roll-out) mode for the mouse actions, the adjust transition length mouse action (SHIFT+ CTRL+ F4) will produce an irrecoverable error if the transition length is reduced to zero, or is zero or close to zero before you start. The only option then is to do CTRL+ ALT+ DEL and end the Templot task from the list. You won't lose any template data other than the current/control template -- background templates will be restored when you restart Templot. But you will lose any unsaved background shapes. A similar error may occur when adjusting the transition start (SHIFT+ CTRL+ F3), but in that case it's recoverable by ...
... Yes, one or both templates can be curved. If the radii are not the same or not curving in the same direction, the result is an irregular diamond-crossing (in which the crossing angles at each end differ). Templot will normally set curviform V-crossings in this case. regards, Martin. posted: 12 Apr 2017 13:22 from: Panos Tsirigotis Hello again. I ve tried but I get the following message: "Sorry, this function is not available because the control template contains a transition curve. If the intersection is not within the transition zone, try again after using the[ tools> make split>] menu options accordingly. If the intersection is within the transition zone, you may be able to perform this operation manually by moving the fixing peg along the track (CTRL+ F8 mouse action) ."

... is under construction now and will have 12 through storage roads, each about 30' long. The lower level will be about 18" below the scenic level which will allow full access to the storage roads for track cleaning and point repair etc. Joining the two levels will be a spiral at a gradient of 1:100 which takes three complete circuits of the room before emerging at the upper level. The scenic side will be mainly urban with brick cuttings and retaining walls. Period will be late '60's, ECML in the transition from steam to diesel.

50. My Magnum Opus
... West Highland Line, with the intention of building it to reflect its NBR days. This is intended to be a P4 layout. (For those of you who model in "N gauge" you may be familiar with the Loch Oran layout by David Harrison, which is also based on Crianlarich.) I'd appreciate any comments and Peer Reviews (although many of you are far too good for me to call you peers). I particularly have a problem with template no. 30, "Goods Sidings" which is a transition curve and shows a minimum radius of 12.6 inches! It would be possible to move this closer to the main lines but I'd prefer to keep the distance to remain closer to the prototype layout. Don't worry about the runaround loops- they may never get built: it's the station and goods and maintenance sidings that need to be done first... I await any comments.

... topic: 1715 TDV Transition Problem ?? posted: 3 Dec 2011 23:10 from: Rob Manchester Hi Martin, I managed to get some strange patterns on the screen today when adjusting the the 1st and 2nd radius of a transition curve. The 'errors' occur when finely adjusting the radius. You can work through it by going just a bit further on when the display returns to normal. TDV doesn't crash at all. It is hard to re-produce the problem but if I do I will stop and leave everything where it is while saving the templates in a box file for you. One of the screenshots is attached. Anybody else seen this? Rob Attachment: attach_1256_1715_Transition_crash _1.jpg 303 posted: 4 Dec 2011 05:31 from: Martin Wynne Hi Rob, Thanks for posting the file. It's a long-standing known issue, not related to TDV. Essentially you created a transition curve which was too gentle for the maths processor in your computer. "Too gentle" means the radius was changing by too little in too ...
... topic: 239 Basic commands- terminus design posted: 16 Nov 2007 13:23 from: Gordon S Hi Martin, at long last I am making the transition from WinRail and started to take my first steps last night, just by your recommendation of using the F7 key... Some very simple questions that will allow me to move further. Apologies for the simplicity for those more experienced. 1. Simple plain track. At present I am generating a template and then converting to plain track. Is this correct? If so is there a quicker way? I'm sure I'm going a long way round using Template, quick set, selecting a B7, Template, convert to plain track, F7 to add and then F3 to lengthen. 2. Parallel tracks. I have generated a length of plain track, guessed the curve and length and added (20) a length of plain track. This is not truly parallel to (23). How would I achieve this? 3. You very kindly generated a 1:7 slip ...
... set the TS spacing at 92mm and the MS spacing at 120mm: 2_011419_430000000.png A slightly smaller spacing than 92mm would be possible on the larger radius tracks, but it's more practical to keep them the same to avoid errors in construction and tracklaying. The .box file for this is attached below. If you adopt it you will need to realign the pointwork, but it's all good practice in Templot. But you might want to wait for my next reply, because the best way to reduce the centres into straight track is to use transition curves. p.s. a quick way to see which side is TS and MS on plain track is to put the timber numbering on: trackpad> trackpad background options> trackpad background templates detail... menu item. The numbers are always on the MS side. regards, Martin.

... topic: 1600 The hollow triangle symbol posted: 24 Aug 2011 20:38 from: Simon Dunkley Just a thought, and posted here following an email exchange with Martin, but since the backspace key can be used to access recent commands, in many instances it would be useful to use the empty triangle symbol to toggle between related commands, so that if F9 is selected for a half diamond, then clicking on the triangle will toggle to the F10 functionality, and vice-versa. If you have a transition curve, then clicking on the triangle when adjusting the radius (F6) toggles between the first and second radii, so you can see what I mean if it is not clear. In a similar vein, I would find it useful to be able to toggle between setting the start point of a transition curve, and setting the length of the transition. Martin thinks the basic idea has merit, so I wondered if it might be useful to open up the topic for further suggestions of paired (or triplicated, maybe?) ...

... topic: 2456 Slip in transition curve posted: 11 May 2014 22:22 from: Martin Wynne On RMweb Michael Woolford asked about inserting a double-slip in a transition curve, see: http://www.rmweb.co.uk/community/index.php?/topic/67805-converting-to-em-and-handbuilt-track/page-5 #entry1447437 I thought my reply might interest members here: Hi Michael, A slip in a mathematical transition? No, or at least not in traditional chaired track. Transition curves are normally used where there is a cant gradient (increasing superelevation) which means in effect that there is a twist in the track. Switch rails inserted in a twist wouldn't be able to slide properly or align with the stock rail. There is no major reason not to insert a slip as a special one-off in a flat transition curve, but I'm not aware of any. What is much more common is for an effective transition to be created by using a different fixed radius between each crossing in a ...
... topic: 3491 Slew or Transition where curve difference isn't that big posted: 19 Aug 2019 16:08 from: richard_t Hi I have curve that needs to slew around a bridge span- the radius of one curve is 1800, and I'd like it to finish at 1747.44mm. I can't use a transition because the amount of change isn't big enough, and I'm constrained at both ends of the curve. I *think* I need a slew, and I've tried to do it, but the results are rubbish. I've closed a screen shot of the area (the control template and the marker coloured template are the two I wish to join), and a copy of the relevant bits from the box file, if anyone cares to lend me a hand... Thanks in advance.

... topic: 2688 Relationship between length of track and offset in s-curve transition posted: 15 May 2015 13:09 from: Godfrey Earnshaw Hi All, Does anyone know if it is possible to determine the offset when creating an S-curve transition. For example if I have two parallel tracks on 60mm centres (4mm scale) can I pick a length of track that will, when S-curve transition is selected, have an offset of 60mm. I know I can create an offset by having two contra curved tracks coming off the ends of the straight tracks but I wondered if I could do it directly. Thanks Godders posted: 15 May 2015 13:26 from: Martin Wynne Hi Godders, You can set up the offset in a transition curve by adjusting the centres and radii of the 1st and 2nd curves, and then using the make transition function to create the transition curve between them. However, I think what you are looking for is a slew, not an S-curve transition: slew_marks.gif All about slewing here ...
... much reduce the length of the shed road as in Tom's example. To link those two templates as they stand is going to need a sharp reverse curve. But the B-6 turnout is much longer than it needs to be. Because of the contraflexure it can be shortened significantly -- here I made it a 9ft-switch 1:5 turnout, which still provides a radius of 1165mm (46"). Change to a curviform V-crossing, make a branch track, and insert an S-curve transition in it. Then adjust the length and position of the transition zone until the curve doesn't quite kiss the shed road, close to the end of it: 2_030829_590000000.png Then you can use the make transition function as shown in the above link to complete it. Because the control template is itself a transition curve, it is necessary to select its 1st radius in the make transition dialog. The shed road template can then be deleted and the new template extended to replace it: 2_030829_590000001.png I also normalized the first S-curve ...
