“The Lego 732 Locomotive is very similar to the 112 Locomotive with Motor, but the differences here are that it didn’t come with any train tracks. This set includes 95 pieces including the 702 12v motor. It is an alternative for the more expensive train sets, so if you just... More want a train locomotive, this is the one.”

About Trains 12V

In 1969 LEGO released the 12 volt train sets as part of the Blue Era which was named because of the rail color. These 12V train sets used additional conductor rails mounted between the standard 4.5V rails and 12V motors contained in the same housings as the 4.5V motors, but with additional metal contacts attached to the bottom of the housings.

12V consists of 17 sets that ran from 1969 to 1970. As of today, 722-2 12V Electric Train with 2 Wagons is the most valuable 12V set with an estimated new/factory sealed value of $1,067.
