Remote Control
Railway operation would be impossible without an effi­cient signalling system. Railways attach great importance to signalling not only because signals govern train move­ments but also because they are the most important devices which assure safety.

At first all signals available at stations were manually operated. To change their indications it was necessary for the signalmen to walk a great deal until someone, now unknown, suggested that the signals should be connected by wire. That permitted any number of signals to be oper­ated from one place. This control from a distance, or remote control, is one of the most valuable inventions in the railway history.

In the middle of our century there appeared electronic remote control systems. When these systems appeared rail­ways quickly adopted them. Indeed, the railways were the first to adopt these new systems on a wide scale.

One of the principal reasons for utilizing remote con­trol in railway signalling is to lengthen the railway sections that can be governed from one control panel. A large con­trol area permits more efficient handling of traffic. With remote control the chief operator can provide the running of trains with as little delays as possible thereby increas­ing the track capacity. As a result, a good deal of rail­roads have eliminated one track on the double-track rail­road.
