HI
I'm new to N scale sets, having found my dad's Old Timer Jupiter locomotive, tender and a few freight cars, along with track and a blue transformer.  Seems everything hooks up OK, but when I dial the transformer, the tender makes whirring noises, but nothing moves.  Having much more experience with O gauge Lionel, I thought the locomotive pulled the train, and just setting it on the track would make it go.  Am I missing something or is the locomotive not working properly?  Any help/suggestions, or directions to instructions on this website would be appreciated.Thanks!
