I just purchased a Baldwin 9670 engine with the numbers 34942 in the small circle on the side.  It also has Bachmann written on the bottom.  I am not sure what I got or how to operate it as it came with no instructions of any kind.  It did come with a bunch of track, a tender, two box cars, a Crest 10 amp DC power supply "ULTIMA CRE-55460", an "Aristocraft trains" "TRAIN ENGINEER WALK AROUND CONTROL SYSTEM" ART 5471 receiver 10 amp with remote control.  My 5 year old son loves trains and I was hoping to have this running for him Christmas day.  I can't get the engine to run.  The volt indicator shows I have power on the track.  Any suggestions to get this running?
