Okay, again, I hope someone can help. Getting into O gauge, and want to set up a simple loop to loop layout. I am not sure Lionel 0-27 manual switches feature a non-derailing capability, preventing derailments when a train enters the switch from the "wrong" direction. It would be great to set up a reversing loop with a manual switch, either 0-27 or Fast-track, and just sit back and watch the trains go around the loop, without having to throw the switch each time. Is this possible with 0-27 and/or with Fast-track? Any other kind of 0 gauge switch do this? Call me lazy. I just wanna watch the train roll and work on buildings and scenery.
