LEGO 703 12V Replacement Motor was a Trains set released in 1969. It consists of a 12V replacement motor, identical to the 4.5V version but designed for the 12V system, providing an option for motor replacement without buying a new set.

The current value for a new and sealed 12V Replacement Motor is estimated at $39, with an average annual growth of approximately 5%, which is higher than other 12V sets. On the open market, a used set will sell in the range of $31 and $35, depending on its condition.

“The Lego 703 12 Volt Replacement Motor is the same as the Lego 104 4.5 volt replacement motor, only difference its for the 12 volt line. Since this is a brand new line, it is prone to break from time to time, so if it breaks, you wont have to buy another set.”

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 $1,164.
