Thanks Mitch and Mike.
Dave, so far I really like the way the Lionel cars work on the hump. Much smoother than MTH, but more testing is needed. Now I have to get power to those 5 switches to really have some fun. I think it's going to take two people to run it, one on the throttle and the other to throw the switches. I'm going to have 6 push buttons mounted to the fascia, one for each track. A diode matrix will be used to select routes, throwing as many as three switches at a time.
It just occurred to me that I never tested the center route on the 3 way. That's where the ground feed to those rails would be needed. If the engine stalls there, I'll have to put in the micro switches.
