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.

ДН is essential that а пйТгшег of new remote control cfevfces should be adopted on railways. 2. Westinghouse suggested that compressed air he utilized to operate brakes. 3. Fixed signals are insfa'fied at the entrance to each block lest a train should be admitted to a block which is occupied by another train. 4. With the increased number of trains on railways it became necessary that the time interval method be replaced by a more satisfactory system of train operation. 5. The engineer demands that consid­eration should be given to the efficient repairing of the trackside control devices. 6. A great deal has been done in order that the trains be provided with reliable brakes. 7. It is desirable that the methods and systems available should be more widely utilized for in£j:6&$mg safety and track carrying capacity. 8. The small colour-light signal giving the same indications as the wayside"~signals is in­stalled in the locomotive cab Jest,bad weather should pre­vent the driver from reading danger signals. 9. Urgent meas­ures must be taken in order that train delays should be eliminated on the newly-built railway section.
