A number of years ago, Model RR had an article on power routing/switching using SPDT slide switches for A yard ladder. I cleaned out my library ( gave all of my collection to a small RR Museum ) now in need of info for a new layout. will someone please post article or post issue information
Thank you

Don't have your answer, but try this.
Go to the top of this page, click on RESOURCES, then clickk on Index of Magazines. Knowing the magazine and approximate time frame should help narrow your search down. You may also find other articles on similar situations.
Good luck,
One question: Were the slide switches mechaniclly linked to the turnout points?
If the SPDT switches simply power the hot frogs of the turnouts, the only yard track that will have power is the one for which the turnouts have been lined up. Contact sets on electric switch machines can be used in the same way. If there's a second set of contacts on each machine it's easy to connect panel indicators (lamps or LEDs) to indicate which track has been selected and is powered. This is exactly how I've rigged my single-ended staging yards.

Golly gee, Chuck,
For one who has contributed so much to this forum, and by so much I mean encyclopedic, why in heaven don't you show a unique Avatar? You are not just a shadow!

switches are both mechanically & Electrically active and yard is double ended
