Reply to "Trolley with reversing bumpers"

I don't know your trolley control system.  Dallee had an additional control for station stop.   Without the bumpers, required a trolley with Forward, Neutral, Reverse control system.

It sounded to me as if the OP had a "bump and go" trolley.  These which have no e-unit or digital reversing unit.  These are simple- a bumper at each end with a mechanical connection to a slide switch in the trolley.  AC power from the track is converted to DC by a bridge rectifier in the trolley, which allows reversing by a change in polarity to the DC motor.
