BAY AREA RAPID TRANSIT

BAY AREA RAPID TRANSIT DISTRICT (BARTD) IS A 75-MILE, DUAL-RAIL, RAPID TRANSIT NETWORK WITH HIGH-SPEED ELECTRIC TRAINS SERVING 33 REGIONAL STATIONS IN 15 COMMUNITIES. THE SYSTEM'S LIGHT WEIGHT VEHICLES WILL BE CAPABLE OF TOP SPEEDS OF 80 MPH AND OPERATING SPEEDS OF 50 MPH, INCLUDING STATION STOPS. EACH CAR WILL ACCOMODATE 72 PASSENGERS IN UPHOL- STERED SEATS AND WILL FEATURE CARPETED FLOORS, AUTOMATIC AIR CONDITIONING, A SPECIALLY DESIGNED READING LIGHT, AND WIDE WINDOWS. POWER TO PROPEL BAY AREA RAPID TRANSIT (BART) TRAINS WILL BE 1,000 VOLTS OF DIRECT CURRENT, SUPPLIED TO THE VEHICLES FROM A TRACKSIDE THIRD RAIL. IN ORDER TO INSURE HIGH OPERATING SPEEDS AND ELIMINATE SWAY, BART TRACKS ARE SPACED 5 FT. 6 IN. APART. BART TRAVELERS WILL TRAVEL ATOP 25 MILES OF ARCHITECT-DESIGNED AERIAL STRUCTURES, THROUGH ANOTHER 25 MILES OF SUBWAY, AND ANOTHER 25 MILES OF SURFACE TRACK. THE TUBE IS MADE UP OF 57 INDIVIDUAL TUBE SECTIONS, CONCRETE-LINED, AND FLOATED INTO POSTION OVER A TRENCH DREDGED ACROSS THE FLOOR OF SAN FRANCISCO BAY. AN AUTOMATIC TRAIN CONTROL SYSTEM, BEING INSTALLED AT THE LAKE MERRITT STATION IN OAKLAND, WILL BE RESPONSIBLE FOR THE STARTING, STOPPING, SPEED LEVELS, DOOR MOVEMENTS, AND PROPER SPACING OF TRAINS. THE COMPUTER CAN MAKE AS MANY AS 6,000 COMMAND DECISIONS EVERY HALF SECOND FOR THE CONTROL OF AS MANY AS 105 TRAINS ON THE NETWORK AT ANY ONE TIME. THE AUTOMATIC FARE VENDING AND COLLECTION SYSTEM IS DESCRIBED. AT THE MOMENT, THE TOTAL CONSTRUCTION PROGRAM IS MORE THAN 65 PERCENT COMPLETE. COSTS FOR THE SYSTEM ARE REVIEWED. COMMUTER TIMES ARE EXPECTED TO BE SLASHED AS AS ONE-HALF TO TWO-THIRDS WITH BART. THE PEOPLE-CARRYING CAPACITY IS 30,000 SEATED PASSENGERS PER HOUR ON A SINGLE LINE IN ONE DIRECTION.
