One of the more unusual pieces of M*A*S*H memorabilia is the Bachmann HO scale train set. I’m not a model train person so read this Wikipedia page for some information about the “HO scale.” I’m not exactly sure when this set was released but according to Tony Cook’s HO-Scale Trains Resource it was featured in Bachmann’s 1983 catalog, meaning it was likely available in 1983-1984. It features a 45″ x 36″ oval track and 89 pieces, including five train cars, a plastic jeep, a plastic helicopter, a water tower, 10 cardboard buildings, 48 plastic figurines and paper to be used as a mountain backdrop. According to Toy Soldier HQ Inc, the figurines were not special army people but the regular Bachmann train figurine set made up of 24 men, women and children, in both white and green.
One of these sets sold on eBay a few weeks ago for $296.01. It seems that the train cars themselves were released separately and can often be found for sale on eBay. If there are any model train enthusiasts reading this know anything about the Bachmann HO scale train set for M*A*S*H, please add your thoughts in the comments.
