Thanks for all your replies.  Living in Philadelphia, I was able to take the engine to Irv, who works in the Repair Department for Bachmann.  He was very cordial and replaced the part on the spot.  A good friend sold me a circle of track and a transformer and all is working fine.  This engine looks exactly like the Pioneer Engine currently offered by Bachmann.   I have two questions: What type of white grease do you lube the gears with and is the engine supposed to smoke?

Thanks for your help,

Good Evening All,

I have been given a set of Bachman Large trains, used condition by one of my fellow workers.  The engine is a 4-6-0 and the road name is Atchison, Topeka & Santa Fe.  The engine is burgundy with gold lettering.  I was told that they were 20 plus years old.  Not sure of their age.  I know very little about G gauge trains.  I have remounted one of the coal car trucks last night and was working on the engine today.  I need the large part under the smoke stack at the bottom of the engine where the wheel rods slide back and forth on go into these forward pistons.  I removed the four screws on the bottom of the engine and the longest fastener holds the piece I need.  Can one obtain parts?  I have no track, no clips to electrify the track and no transformer.  What voltage do these trains run on?

Thanks for your help,

Bill West
