“The Lego 166 Flat Wagon is an accessory piece for the 4.5/12 volt line. The set includes 53 pieces, and of those pieces are 8 pieces of track, and two minifigures. His is one of the first sets to have minifigures with printed on torsos, while you might thing, what’s the big... More deal? It is revolutionary back then, but now its not all that impressive because we have all of these things. The Flat wagon is a attachment to any train, and will carry any excess cargo you might have, and put it in there. It will be a nice addition to any Lego train track.”

About Trains 4.5V / 12V

4512V covers the LEGO trains of the 4.5 V and 12 V systems from the 1970s and 1980s. The 4.5 V trains ran on batteries carried in a wagon or tender, while the 12 V trains drew power from conductor rails laid between the running rails, fed by a transformer with a speed control. Until 1980 the track was blue, which gave these years the name of the Blue Era.

4.5V / 12V consists of 83 sets that ran from 1972 to 1986. As of today, 7750 Steam Engine with Tender is the most valuable 4.5V / 12V set with an estimated new/factory sealed value of $6,368.
