Hi all,

I am currently attempting to get to grips with templot, I was struggling with creating a Y turnout which Martin kindly did for me.  Having got the basics in place it appears I have rather more room for the Y turnouts than I previously realised.  I have tried redrawing with more forgiving angles but am completely baffled one the half diamond is inserted as I have no switch blades and only half of the check rails.  I have attached the box file which currently incorporated the Y turnout template that Martin created, but as you can see I have room for much more gentle curves, how do I stretch them please?

To give a little background to the trackplan, this is the lower part of the first of free modules, the 3 tracks looping off are a mainline and a preservation branchline which go onto a helix to the upper levels, the next board along will be plain line only (at fiddle yard level) and the last board will be a mirror image of this one.  If anyone can spot any potential improvements any advice would be greatly received as I am currently on a very steep learning curve.  The trackplan so far is all non scenic.

Kind Regards,

Pete

Hi Pete,

Welcome to Templot Club. :)

Although they have been on my to-do list for years, symmetrical Y-turnouts are not supported natively in Templot. That's because on the prototype they are really quite rare, despite being much loved by modellers.

For example your design is difficult prototypically, because a) having two turnout stretcher bars exactly opposite each other causes problems with the rodding runs to the signal box, and b) on passenger lines your Y-turnout would need to be a wide-gauge style of catch points to protect the outer lines, and c) that makes the interlocking and signalling more complicated than needed.

Much more likely on the prototype would be something like this:



The middle road continues to a short spur, which is a useful place to park an odd wagon or brake van. A tandem turnout then provides two conventional crossovers to the outer roads, and the turnouts are conveniently staggered.

However, to return to your design, a symmetrical Y-turnout can be created using an irregular half-diamond template, with the peg on split deflection to create a switch front.

I set the K-crossing angle to 1:24, which conveniently means you can use "A" size switch blades and the timbering from 1:24 switches. Then a V-crossing angle of 1:4.5 looked about right to fit your scheme:



The .box file for this is attached below.

This is towards the "more experienced" end of Templot usage, so rather than try to describe it in words I will make a bit of video later. But not just at the moment because I can smell something burning inside my computer and need to investigate before the smoke comes out. :(

regards,

Martin.

Hi Pete,

I have now made a video showing how I created your Y-turnout.

Sorry it is so scruffy, but even as it stands it has taken me a couple of hours to compile and add a few notes.

For best results, click this link and watch it in the Templot Video Player:

 http://templot.com/fbr/scruffs/y_symm_for_pete.fbr

If that doesn't work, you can watch it (but in much poorer quality) here:

Ask again if anything is unclear.

regards,

Martin.

Sorry about that.

I have updated the link in the previous message.

cheers,
