SAO PAULO'S NEW METRO BEGINS REVENUE OPERATIONS ON SCHEDULE IN THE SECOND HALF OF 1974. BY 1980 A LENGTH OF 66.6 KM WITH FOUR LINES AND 68 STATIONS IS EXPECTED. THE ENTIRE 200 KM NETWORK IS SCHEDULED FOR COMPLETION IN 1990. THE SYSTEM WILL INCORPORATE AN AUTOMATIC CONTROL SYSTEM THUS INCREASING EFFICIENCY BY COMPUTERIZED TECHNIQUES OF LINE SUPERVISION, TRAIN OPERATION AND TRAIN PROTECTION. THEY PLAN FOR AUTOMATIC TRAIN OPERATION, A SYSTEM WHICH WILL TRANSMIT TO TRACKSIDE INDIVIDUAL TRAIN IDENTITY WHICH THE LINE SUPERVISION SYSTEM USES FOR AUTOMATIC ROUTING OF TRAINS THROUGH THE NETWORK. THE CENTRAL LINE SUPERVISION WILL ALSO BE COMPUTERIZED. IT WILL CHECK CORRECT TRAIN MAKEUP, DETERMINE DEPARTURE TIME, SEE THAT TRAINS ARE PROPERLY ROUTED AND REQUEST TRAIN SPEED ADJUSTMENTS. THE SYSTEM'S ENTIRE STATUS WILL BE ON CENTRAL DISPLAY BOARDS, ALSO COMPUTERIZED. THE COMPUTER CONTROL SYSTEM WILL BE VALUABLE ALSO IN ITS ABILITY TO SUPERVISE OPERATIONS TO SEE THAT TRAIN SCHEDULES ARE MAINTAINED AS CLOSELY AS POSSIBLE. TO TEST PROPOSED CHANGES IN THE SYSTEM, AS PASSENGER LOADS INCREASE, A SIMULATION PROGRAM CAN BE CREATED USING EXISTING EQUIPMENT.
