Maybe I should have been more clear. I have a Norman Rockwell trolley set which runs on track power. The track is powered by 4 AA batteries through a USB cable. I presume that the trolley needs no more than 5 volts to operate. Should I try using this trolley on track using a conventional DC power supply?

I should add that a trolley packaged separately does not have enough voltage provided to run on this arrangement.

Will the Norman Rockwell Christmas Trolley (battery powered) run on the Village Street Car (transformer powered) set?
