Hi, I have the trolley auto reverse set! It works great! The set comes with plenty of track and you can add additional track to expand. Any trolley or engine will work.

I just purchased Bachmann Acelela Express DCC. I am using 11.25 radius curve ez track. The café power car keeps derailing. Other shorter cars are ok. What radius should I use so it won't derail?
Thanks to anyone that can answer.
