About LEGO Trains 4.5V / 12V

In 1972 LEGO released the 4.5V and 12V train sets as part of the Blue Era which was named because of the rail color. These 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.
1980 LEGO Sets
1980 refreshed the 12V Train system with remote-controlled points, signals, lighting, and decouplers, creating one of LEGO’s most sophisticated play ecosystems. Classic Space continued its rapid growth with larger craft, bases, and color-varied astronauts. Expert Builder (the forerunner to Technic) advanced functional builds with more gears and linkages, while LEGO Dacta was established to bring learning-through-play into classrooms.
