When was the railroad crossing warning system invented?
Highway-rail crossing warning system technology dates back to 1870 when the track circuit was invented. The idea of using electric current in railroad rails for signaling was an idea that had been suggested as early as 1848.
How are railroad crossing gates raised and lowered?
At that time, crossing gates were hand-operated by means of a crank mechanism. The gates were lowered and raised by means of cables or chains running through underground piping from the gatekeeper’s crank base to each individual gate at the crossing.
