Hello again.
Why it is not possible to split separate exit tracks for a parallel V-crossing.
Is there any alternate way to split a separate exit track when the V is parallel?
Thank you in advance

Change to a regular V-crossing, and then click tools > make return curve.
You can then also split the exit track on the turnout.
parallel V-crossings are a bit of an oddity in Templot, essentially a legacy option left over from the early days. If I was starting again I doubt that I would implement them.
In fact they are not fully developed, as you found. For example you can't split the exit, and the turnout-side platforms don't work. Those items are on my NOD list (nice one day), but not near the top.
They do have the advantage that they work for a transition curve template, whereas make return curve does not. But that is easily overcome using the make transition functions.
The big advantage of having a separate template for the return curve is that a turnout can be inserted in it.
There is a very old tutorial about return curves here -- it needs updating:

Martin.

Thank you Martin but as I can see from the tutorial a "return curve" function makes a curved brunch track from the turnout while I need to exit straight from the turnout and make the curving at a distance from the turnout. In attached screenshot you can see:
The ladder above is made with turnout parallel V-crossing
The ladder below is made with return curve
I dont know which one is the correct transition in the real thing but I do like the above.
Regards

Hi Panos,
I'm sorry, I don't understand your question. It's better to post your .box file rather than a screenshot so that I can see what you are trying to do.
If you want a return curve with an intervening straight section, there are various ways to do it. For example:
1. set the required TS adjacent track spacing and make an ordinary crossover.
2. extend some approach track on the turnout ( F3), and then tools > make split > make plain track turnout road > on external geometrical radius.
3. on the original turnout tools > make branch track. Use peg/align tools > extend/shorten to meet to set it to the exact length.
Alternatively, you could use the make transition functions. That gives you more control over the radius, and would allow a turnout to be inserted in it and roamed into position. More about that method at:

regards,
Martin.

Thank you Martin.
With the ordinary crossover function I got the idea.
Kind regards
