I have received as a gift an American 4-4-0 Steam Locomotive with tender.  I have had no experience with other trains.  However as an 82 year old retired engineer I have normal familiarity with mechanical devices.

This unit seems to work correctly except the wheels just spin and no motion seems possible.  I have not used any lubricant and the track is wiped clean.

Is there a trick I am not aware of?  Can anyone offer any advise?
