From my personal collection, I bought this set new in 2001 and it is still sealed in plastic from the Micro-Trains factory. The set includes a GP-20 loco, a 40-foot box car, a 50-foot box car, a 50-foot flat car with a load of Christmas trees, a 36-foot caboose, oval track (20 inches by 31.5 inches) and a power pack.
