DESIGN PRINCIPLES FOR CONSTRUCTION OF HIGH-SPEED MOTOR TRAIN UNITS AND EXPERIENCES WITH MAINTENANCE

Based on the test results of 1962 obtained with six prototype coaches for the New Tokaido Line (NTL), in Japan, a design for a standard motor coach was started and further improved in 1964 after the opening of the NTL for the purpose of reducing maintenance cost and improving the operational efficiency. Two permanently coupled motor coaches with all axles driven constitute a single unit from the viewpoint of operating and electrical function; the electrical equipment is arranged so that an equal weight distribution is achieved as far as possible. For traction motors undulating current motors are in use with amplitude control and silicon rectifier bridges. The extremely low rate of disturbances of motor coaches in operation is the result of a mature and tested design and particularly of the maintenance system of the NTL; since 1967 only 0.03 train delays (more than 10 minutes late) per one million traction km were registered.
