AUTOMATING THE RAILWAYS; TELEVISION FOR RAILWAYS
At present, control of the high-speed trains is semi-automatic since they are automatically forced to comply with permissible speeds at any given instant. Stops at station platforms are under the driver’s control. The whole line in Japan, for example, is directly controlled from Tokyo and for this purpose is divided into four systems. The state of the line is continuously surveyed and information is transmitted at high speed to the control centre. Each train automatically identifies itself by generating a unique frequency as it passes fixed ground equipment.' and the information is displayed on the control system at Tokyo. Trains entering stations automatically set the points system according to classification, i.e. whether super express, limited express or freight.
One interesting but simple safety feature is provided to enable anyone on the line to stop the train in an emergency and consists of push-button switches placed at intervals of 50 m. Operation of the switch shorts the track circuit, and the consequent indication in the driving cab of an approaching train causes the brakes to be applied automatically when at an appropriate distance from the danger position. All the safety circuits are fail-safe, and the possibility of an accident due to human fallibility has been virtually eliminated. Current developments intended for future installation would include programmed control, obstacle detection by a guided radar, controlled braking to a prescribed point and centralized computer control.
Extensive work is under way 2 in our country to utilize television technique in industry, science and agriculture.
Some years ago one of the research institutes of the Soviet Union designed a television apparatus which is now used in railway transport to record the serial numbers of freight cars arriving at a station.
As a train pulls in at a station, somewhere at a distance of ten kilometers an operator sees this train on the screen of his television set. The operator reads aloud the serial number of the freight cars and they are recorded by a tape recorder. On another television set the operator can see all the railway lines in a station. The operator only has to press a button and another station will appear on the screen. These installations are being used in connection with the shifting of freight cars. The Central Research Institute of the Ministry of Railways is designing a new television apparatus which will enable engine drivers «to see» the condition of the freight car even when it is dark.
