I want to control the entire crossover piece with one controller.  Normally, I would connect the 2 "output" wires together and connect to the controller.  However, Bachman wires come with as a 3 wire with connector.  How can I do this?

Why doesn't Bachmann make 1/3 or 1/2 tracks in both curved and straight?
I've hit a snag in trying to make a layout I designed and need a few short pieces (less than 12")

I just bought the Pennsylvanian and it comes with 20 pieces of track & a transformer.  I'd like to expand the number but don't know if the transformer will be able to handle the increased size.  Is there a maximum number of tracks I can use with the transformer from the set?  What are other alternatives/transformers available?

I received the subject train set for Christmas and would like to set up a model in the basement.  How can I buy more passenger cars (Pennsylvania RR) that are Tuscan Red to match those in the original set?
