1. AN AUTOMATIC SIGNALLING AND TRAIN CONTROL SYSTEM COMPRISING:
- A TRACK, A SERIES OF CALIBRATION SIGNALLING DEVICES SPACED ALONG SAID TRACK EACH PRODUCING A SIGNAL UNIQUE TO THE LOCATION THEREOF;
A TRAIN ON SAID TRACK, SAID TRAIN HAVING THEREON A CALIBRATION SIGNAL RECEIVER, FIRST REGISTER MEANS CONNECTED TO SAID RECEIVER PRODUCING AN ELECTRICAL CODE SIGNAL REPRESENTING THE SIGNAL RECEIVED FROM THE CALIBRATION SIGNALLING DEVICE LAST PASSED BY SAID TRAIN, AN ELECTRICAL PULSE GENERATOR ASSOCIATED WITH A WHEEL OF SAID TRAIN TO PRODUCE AN OUTPUT PULSE FOR EACH INCREMENT OF ROTATION OF SAID WHEEL, A STEPPING DEVICE CONNECTED TO THE PULSE GENERATOR TO RECORD THE NUMBER OF INCREMENTS OF ROTATION OF SAID WHEEL, AN ENCODER FOR TRANSLATING THE TOTAL OF SAID INCREMENTS INTO SIGNALS REPRESENTING BINARY NUMBERS, SECOND REGISTER MEANS CONNECTED TO SAID ENCODER TO PRODUCE AN ELECTRICAL CODE SIGNAL REPRESENTING THE TOTAL STANDING IN SAID STEPPING DEVICE, A SIGNAL GENERATOR PRODUCING AN ELECTRICAL CODE SIGNAL UNIQUE TO SAID TRAIN, THIRD REGISTER MEANS FOR PRODUCING ELECTRICAL CODE SIGNALS RESPECTIVELY REPRESENTING START, STOP AND RUNNING SPEED CONTROLS TO BE APPLIED TO SAID TRAIN, A REPORT SIGNAL TRANSMITTER, A PROGRAMMER INCLUDING MEANS TO READ THE ELECTRICAL CODE SIGNALS FROM SAID SIGNAL GENERATOR AND ALL OF SAID REGISTER MEANS INTO SAID REPORT SECOND REGISTER MEANS, SECOND REGISTER MEANS, SAID THIRD REGISTER MEANS BEING ADAPTED TO OPERATE A TRAIN CONTROL DEVICE FOR APPLYING START, STOP AND RUNNING SPEED CONTROLS TO SAID TRAIN IN RESPONSE TO CORRESPONDING SIGNALS LOADED INTO SAID THIRD REGISTER MEANS, AN INSTRUCTION SIGNAL RECIEVER AND MEANS CONNECTED TO SAID THIRD REGISTER MEANS FOR LOADING THEREIN CODED INSTRUCTION SIGNALS RECEIVED BY SAID RECEIVER, AND A CENTRAL STATION INCLUDING A REPORT SIGNAL AND INSTRUCTION SIGNAL TRANSCEIVER, AND A COMPUTER CONSTITUTING MEANS TO ANALYZE THE CODED REPORT SIGNALS RECEIVED FROM SAID TRAIN VIA SAID REPORT SIGNAL TRANSMITTER AND TRANSCEIVER AND TO TRANSMIT AND CONTROL AND PREDETERMINED CODE SIGNALS THERETO VIA SAID TRANSCEIVER AND INSTRUCTION SIGNAL RECEIVER, SAID CONTROL SIGNALS VARYING IN ACCORDANCE WITH DIFFERENCES BETWEEN THE ACTUAL POSITION AND A DESIRED POSITION OF THE TRAIN ALONG SAID TRACK.
