Got an odd one here-I won a bid for what was supposed to be a Holiday Streetcar set, but all I got was the streetcar and the car barn. The streetcar runs fine on my layout, and I'd like to know if I can just add sections of flex-track to the piece of track within the car barn. Will I be making a mistake, or will this work? Is there a special piece at "end of track" that is needed to make the car stop and reverse? Can I use a regular Bachmann power pack like the nice metal ones that came with the on30 sets? Have I become an externally helical threaded fastener capable of being tightened or released by a twisting force to the head? Just asking...........
