Can anyone point me in the correct direction to find a 'Y' turn out?
Or has in been discussed before?
Thanks

I'm sure that "Y" turnouts have been discussed before on the Templot Forum. I'm not sure if it's been discussed here - unfortunately the search engine here discards single characters, so I can't search on "Y turnout".
Anyway, yes, it can be done in Templot. One of the members of the CHEAG area group was after a B6 Y turnout, so I rattled one up for him. The files are attached, as the Templot BOX file and as a pdf file.
There will be someone along shortly to say (IIRC) that true Y turnouts don't occur in nature, and we should be sceptical about using them, but Rule #1 always applies.

Re: 'Y' Turnout
If I was making one and hadn't got a template, I would get two straight turnout templates with the 2 curved roads equivalent to the curved roads of the 'Y' turnout, superimpose one on top of the other and ignore the centre tracks. This sounds to simple though - doesn't it?

Re: 'Y' Turnout
I expect Paul has given all the info needed.
But in case not -
Have a look near the bottom of the page, instructions from Martin how to do it in Templot.

Re: 'Y' Turnout
I have found this old scruff video clip, showing the basics of a symmetrical Y-turnout in Templot:

But very often when folks are asking for a Y-turnout all they really need is an ordinary turnout with a bit of contraflexure. Just use the F6 mouse action and bend an ordinary turnout in the opposite direction from the hand. If it's for a yard or diverging sidings, change the V-crossing to curviform.
cheers,
Martin.

Digest sheet 23.6.3 available at https://www.scalefour.org/members/digests/#23 or for those who have it, on the CD given to you when you joined includes notes on building curved turnouts, including a Y turnout. (Halfway down page 4, LH column.)

Hi Terry,
As described, that creates an ordinary single-sided turnout with contraflexure. The switch deflection is on one side only. To produce such a template in Templot takes about 2 seconds simply to set the curving radius negative in a standard turnout. That's the correct type of turnout to use on the inside of a curved crossover, as suggested there, and generally in running lines.
But it's not a Y-turnout in the normal sense, which requires a switch deflection on both sides, with the angle halved each way (or sometimes other than a 50-50 split). Such turnouts are quite rare on the prototype, and normally found only in yards and sidings. If used in a running line they require a speed restriction over both routes, and are found only on specially constructed long main-line junctions.
Although there is no specific function in Templot to create a split-deflection switch, it is quite easy to improvise one as shown in that old video clip. I get asked about that so often that I'm going to add a tools > make function in the next program update to improvise such a Y-turnout automatically.
Alternatively, a proper prototypical Y-turnout can be built up from partial templates by experienced Templot users.
For years I have been intending to do a complete re-write of the template generator engine to permit splitting of the switch deflection, but it would be a major task and I fear it is now too late. But the open-source version of Templot is available for anyone who wants to have a go at it.
cheers,
Martin.

Re: 'Y' Turnout
Thank you all very much for your prompt replies. I certainly have enough information now to sort something out.
