I was given a Bachmann train set from the estate of a relative that was also a U.P. employee.  It is a Bachmann Set No. 419, Union Pacific Railroad, 102 piece set.  It has a diesel locomotive, gondola car, box car, caboose, livestock car and a box car with "Driving the Golden Spike" on the side.  Does anybody have any information on when it was made and how much it might be worth?  The set is still wrapped in plastic which is ripped slightly on the edges.  Any info. would be greatly appreciated.  Thank You.  Tried to upload a picture, but upload box was full.
