  • Description

    A MODEL OF JET-POWERED "BULLET TRAIN", DESIGNED TO TRAVEL CLOSE TO THE SPEED OF SOUND, WAS TESTED YESTERDAY (SUNDAY) AT KASUGAI CITY, ABOUT 248 MILES (APPROXIMATELY 400 KMS.) WEST OF TOKYO. THE MODEL, POWERED BY A ROCKET ON SUNDAY WAS TESTED BY ITS DESIGNER, PROFESSOR KYUNOJO OZAWA, DEAN OF THE FACULTY OF SCIENCE AND TECHNOLOGY AT MEIJO UNIVERSITY.

    THE MODEL, ABOUT 3 FEET LONG (1M.), WAS PLACED INTO POSITION UPON ITS SPECIAL SYSTEM OF TRACK. THE TRAIN OPERATES ON WHAT IS CALLED THE PILLAR-GUIDEWAY SYSTEM. THIS MEANS THAT A SERIES OF ROLLERS AND GUIDES ALONG THE TRACK HOLD THE TRAIN IN POSITION AS IT MOVES ALONG, GOING FROM ONE ROLLER TO THE NEXT.

    THERE WERE ABOUT 2,072 FEET (600 M.) OF TRACK USED IN YESTERDAY'S TEST, PART OF WHICH WAS A VACUUM PIPE. THE ROCKET MOTOR WAS IGNITED AND THE MODEL MOVED FORWARD AND INTO THE ENCLOSED VACUUM PIPE. THE MODEL WAS REPORTED TO HAVE REACHED A SPEED OF ABOUT 744 MILES AN HOUR (1200 KM/P/H) DURING THE TEST RUN.

    AFTER THE MODEL HAD TRAVELLED THE LENGTH OF THE TRACK, IT WAS DESTROYED BY THE FRICTION OF THE AIR AND WENT OUT INTO THE OPEN AGAIN.

    PROFESSOR OZAWA TOLD JOURNALISTS THAT A MAJOR PROBLEM OF HIS "SONIC PILLAR-GUIDEWAY JET TRAIN" IS THAT OF FRICTION. HE SAID THAT THERE IS MORE ROOM FOR STUDY AND EXPERIMENTATION AND THAT IT WOULD TAKE AT LEAST TEN MORE YEARS OF TESTS BEFORE SUCH A TRAIN COULD BE MADE OPERATIONAL. THERE HAVE SO FAR BEEN 19 TRACK TESTS SINCE APRIL, 1959.

    THE FULL-SCALE TRAIN, POWERED BY FOUR TURBOJET ENGINES MOUNTED UNDER STABILISERS, WOULD BE 720 FEET (220 M.) LONG AND ABOUT 16 FEET (5 M.) IN DIAMETER. THE TRAIN WOULD HAVE FIVE COMPARTMENTS, INCLUDING SECTIONS FOR PASSENGERS, CARGO AND ONE FOR STORAGE OF PASSENGERS' AUTOMOBILES. THE TRAIN WOULD CARRY 1,000 PEOPLE.

    THE PROPOSED OPERATING SPEED OF THE TRAIN IS 600 MILES AN HOUR (980 KM/P/H).
