Among these study items for high speed traveling, the following items are used as main points of judgment.
1/ High speed performances of car
Brake performance, motive power performance, and running performance by bogie
2/ Running stability between car and track
Stability of bogie and adjustment accuracy of track
3/ Bearing capacity of track
Structural strength of track and synthetic capacity of track maintenance
4/ Safety in train passing
Possibility and adaptability of recognition of train approaching
(2) Maximum speed
Because of commercial operation by greatly increased speed, stepwise confirmation and level-up are necessary as described above. By stepwise level- up and confirming of the following items, it is estimated that the maximum speed of a train of high-performance body tilting cars can be set to 150 km/h and used as the prerequisite for the estimation of time reduction.
1/ Stability of braking
2/ Running stability between car and track
3/ Adaptability of people along side the line, train drivers, and workers in railway operation.
The running performance between cars and track basically influences the high-speed traveling stability. For the above fact, many test results of the 160-km/h
