Trains are not held with high esteem today, but that was not the case in 1950’s and 1960’s. Lego first hit the retail scene way back in 1949, capturing children’s imaginations and even developing into theme parks. The Lego train made for a fun toy – not only could children build little scenes but they could also have an electric train chug through them.
There are many varieties within the Lego electric train categories, such as the High Speed City Express Trains from 1985 and the Diesel Freight Trains. Those models in original, unopened boxes could yield about $1,500 to $3,000.
