Curves & Single Slips

Hi Everyone,

Firstly let me say that I am enjoying Templot. This is my first time using and Martin was very kind to provide some brilliant answers, guidence and support when pulling my hair out, and a big thank you for the map. It works perfectly.
I am slowly constructing the Southern Junction to Tynemouth Station, and I am slowly navigating my way round Templot. I have attached Tynemouth So Far, showing where I am up to, which I am quite pleased with.
I have 3 issues and would like to know if anyone can advise?
1) Transitioning Curve or curve with varying curvature. How do you handle it, or where will I find appropriate information to do it? See File Transitioning Curve and the middle plain track. When zoomed into you can see that the Templot curve has stopped matching the rest of the curve. Obviously here I would like to make the whole curve perfectly aligned. At the far right end I have the same problem.
2) Can I have a curved catch point? The file Catch Point shows my catch point in position. However it draws at a tangent of where I would like it to be, and by the track is extended from it becomes out of position too much. Is there a simple fix to this, such as a curved catch point? Or does anybody think the map might not be correct?
3) Slip Issue. I realize that this is a bit of a problem single slip and I am expecting to fudge a bit to achieve the desired effect. However my actual problem is the direction as shown by the straight superimposed over the position of where the slip is. I have tried a single slip in position, and Realize the slip needs to be shortened on all approach and exit roads. My problem is, how do I deal with the angle issue as it does not appear to be curved. The turnout that connects to the left of the slip is a B7 and is a good match at its position on the map.

Any suggestions welcome.

Regards

Michael

Hi Michael,

Good to see you making progress, but I'm tempted to draw your attention to this note on the Templot download page:

It really would be much better to start learning Templot by creating simple track plans, and trying the various functions in the process. Making tracks align to a background map requires a good knowledge of prototype track, what each Templot function does, and how to use it to get the result you want.

These videos cover aligning tracks over a map:

To answer your questions:

1. Put short lengths of dummy template some way apart on each curve, and then use the make transition link function to create a transition curve between them, then delete the dummy templates. More about all that at:

https://85a.uk/templot/companion/make_transition_link.php

2. A set of catch points can be curved the same way as anything else. Create a length of curved plain track and then insert the catch points into it. More about catch points and an animated infographic at:

https://85a.uk/templot/companion/catch_points.php

3. The tools > make slip functions work equally well to create curved or straight slips. However for a curved slip the radius needs to be the same in both roads, so that all the crossing angles are equal (called a regular diamond-crossing).

Create the first curved road in plain track, slide the peg along to the intersection point, store it, rotate the control template to the desired angle, click the background template and use the make diamond-crossing at intersection function. Then delete the background half-diamond, leaving only the one in the control template. Then tools > make slip >.

If the radii differ, so creating an irregular diamond-crossing, you would need to add the slip roads manually. More about slips and a video showing how to do that at:

https://85a.uk/templot/companion/slips.php

Martin.
