The engine is a Lionel 402 and 30 years ago I had the pickups and pantographs replaced because they had broken off.  It is about 17 inches long with a brown color and there are two motors inside.  The distance between the wheels is about 2 ¼ inches.
 I also have 3 train cars, Parlor Car, Observation Car and Parlor/Baggage Cars all labeled New York Central Lines.  I last ran them about 30 years ago and everything worked then including the lights.  I no longer have a transformer to hook up to test them but they were working when I put them away in plastic bags for storage. I also have some track.  Any help would be appreciated.
