SIGNALLING ON A MODERN RAILWAY SYSTEM

SIGNALLING TECHNIQUES ON THE RAILWAYS HAVE PROGRESSED THROUGH THE MANUAL BLOCK SYSTEM TO THE CENTRALIZED TRAFFIC CONTROL, WHERE THE MOVEMENT OF TRAINS IS CONTROLLED FROM A CENTRAL HEADQUARTERS, WITH THE TRACK DISPLAY OF A DISTRICT AND THE APPERTAINING SWITCH AND SIGNAL ACTUATING EQUIPMENT LOCATED IN THE USUAL DESK ARRANGEMENT, OBSERVED AND OPERATED MANUALLY. INTERLOCKING OF CROSSINGS AT GRADE ARE INCLUDED IN THIS SYSTEM. THE LONGER BRAKING DISTANCES RESULTING FROM THE 200 KM/H AND MORE OPERATION, PRESENTLY NECESSITATE MODIFICATION OF THIS SYSTEM, TO INCLUDE CONTINUOUS AUTOMATIC TRAIN CONTROL, WHICH CAN BE PROJECTED ULTIMATELY TO AUTOMATIC TRAIN OPERATION AND TRAVELLING ON INSTRUMENT VISION. THIS ARTICLE DESCRIBES THE USE OF COMPUTERS FOR THIS TYPE OF CONTROL OF TRAINS. THE COMPUTERS ARE PRESENTLY USED FOR INDIRECT CONTROL OF TRAIN MOVEMENTS THROUGH EXISTING SIGNAL EQUIPMENT. THE PROBLEMS OF EXTENDING THIS SYSTEM TO DIRECT CONTROL OF TRAIN MOVEMENTS ARE UNDER CONSIDERATION. THE QUESTION WHETHER THE DIRECT CONTROL OF TRAINS IS POSSIBLE OR ECONOMICAL WITHOUT LOCAL INTERLOCKING FRAMES IS AT PRESENT UNRESOLVED.
