[quote]QUOTE: Originally posted by retsignalmtr i have used them on a layout in the past and they worked well. but they are spst switches and i prefer to isolate both rails for two train operation. they also take up a lot of space on the facia board than the dpdt switches. i can also put the dpdt switches around the layout where they are needed instead of grouped together. [/quote] Why would one want to elecrtically issolate both rails? This method would result in twice as much wiring than what is needed. With the obviouse exception to reverse loops there is no real need to electrically issolate both rails into blocks. On my pike the "outside rail" is the common rail and is electrically continuous, the inside rail has electrical gaps to seperate the blocks and the system works quite well.
