Abstract: To catch the actual state of track irregularities under a train in operation and to analyse the responses of cars in the train to them, it is essential to measure them on the same train. This has been realised with the Japanese super-high speed test train, 300X, which runs at speeds in excess of 300 km/h twice a week, and which aims to travel at speeds exceeding 400 km/h. The measurement of irregularities is done using the inertia method. Data are taken into a personal computer (PC) which has a parallel processing function. As the A/D transform may allow 16 channels at once, vehicle responses such as accelerations of car-body and bogies are also put into the PC at the same time. This system is called the TRIPS (Track Information Processing System).
