Road Crossing
from 10 years

In 1983, LEGO introduced a second wave of sets for the train system, replacing some sets from the first wave. As part of this second wave, LEGO introduced this exciting remote-controlled railway crossing.


This set is the second of three railway crossing for the grey era (together with 7834 and 7835). While the other two sets are manual crossings, the barriers of this set are controlled remotely from a controller connected to the transformer. The lights start blinking when the barriers come down. The controller's house is built on a separate small base plate and looks contemporary, even by today's standards.

The set comes with many parts that are unique to this set. Black/red light bricks, crossing signs, a remote controller (designed to be connected to 7864), a flash light unit, and some intricate wiring. The set also features conducting rails.

This 7866 is another set from 1983 that had a really long life span until 1990. LEGO never released something similar, neither before nor after this set. The instructions show two alternate builds, either with one lane or with two lanes.
