The grey era came with a great number of track options and accessories. Most of them, like this 7865, were released in 1980 and were available all the way to 1990.

A-Model

This set contains a 12V black motor, and as such was intended both as a spare part for replacing broken motors, and as an upgrade kit for push-along or 4.5V trains. Besides the motor itself, the set contains two weight bricks, 2 pistons and 4 connecting rods, and two 2x4 plates which are useful for adding the 12V motor to a steam engine like the one from 7710 or 7810.

Over the years, the set shipped with two version of the steam piston element, with and without interior grooves. The motor itself came in three different versions:

integrated pin on top, power connector without center hole
integrated pin on top, power connector with center hole
separate pin on top, power connector with center hole

If you need to replace a non-working black motor, you needed this set. But when talking about the upgrade scenario, I never understood why they put a black motor into this set. 7720 is the only upgrade-able set that requires a black motor. All other upgradeable sets (7710, 7715, 7722 and 7810) are steam engines, therefore would rather go with a red motor.
