I'm gonna start doing a lift out section on my layout. I want a way to cut of the line electrically so I don't turn any more locos into F-14's. I have a vague idea, should I use a momentary switch, to isolate a section of track, using the bridge section to engage it,or should I use a DPDT switch and do it manually. I'd rather have it someway so I don't have to remember to throw the switch. I will forget to do it too. Any diagrams will be heplful. As always....Thank-you.
