Have you ever just finished doing something on your layout and read a post on the forum the next day and decide to do it all over?
I wired siding to a rotary switch and then read a forum posting about wiring them to toggle switches so you can power everything up. Being that the siding is for a passenger station it it would be nice to have all the cars lighted. The rotary switch was my conventional mind working, I have to start thinking more command control.......
