Long before roads needed traffic lights, railways were using a system of signals to control train traffic. In the early railways, a single track was used for both up-going and down-going trains, and safety depended on spacing the arrival and departure of trains according to time intervals.

These signals consisted of a ball and something that looked like a kite. When the kite was raised on top it indicated danger while if the ball was raised, it indicated the all clear.
