I am brand new to train sets. It has been a life long dream of mine to setup a whole town. I finally got the Spectrum Village Street Car set for Christmas. My issue is that the trolley worked a couple of times. I turned up the speed a little and once it got to the bumper end (hit the bumper), it stopped. Now there doesn't seem to be any power getting to the trolley at all. No lights come on in the trolley when the power is turned on. Could something have jarred loose inside the trolley? What are some suggestions to help trouble shoot this? Thanks for the help in advance.
