It's A Bachmann Train Set: That I have, unopened, still in plastic.   Called this Co. and they have no records of this set, because it was Made Exclusively For Union Pacific Employee's. It says that on the box under UNION PACIFIC R.R..  It's a 102 piece set, with 1 lighted locomotive & 5 cars, also with 36 signs & telephone poles. A 4x8 over & under figure 8 track layout, with bridge & trestles.  Also says; American Heritage Series on the box.  I have reason to think it was made sometime in the 70's, but looking for the exact date. If anyone knows please list.
