Hi, I just found out one of my trolley cars isn't working (what a surprise!) and the other runs but it doesn't sound very well. If anyone coming to GATS has an automatic-reversing trolley car (like the Lionel #60) and would be willing to let it run, please bring it with you. I can set the trolley modules for single-car operation and just let one trolley run back and forth all day. Thanks. Ira
