Re: Need advice on wiring a cross-over and wye junction

Thanks, Blair. Beyond the small ‘Y’ is a very short space and then a double crossover begins which is managed by 2 MRC auto-reversers. But, I’ll put up the diagram, as is, unless you think I need to show more detail of the mainline.

You'll have to post the picture to the photos area here. I saw your post on the Digitrax list. You have two options:
1) The stretch from the crossover to the small 'y' could be fed via an autoreverser
2) The tail of the 'y' could be either fed via an autoreverser, or fed based on the position of the turnout (i.e. feed it from either leg, depending on the position of the turnout; that will require, likely, a relay or other electrical artifice).
I can't tell you which is more appropriate, as I assume your diagram is part of a larger layout. If the tail of the 'y' in fact connects elsewhere, then the electrical 'state of affairs' may be more complicated.
