THE EVOLUTION OF BRAKING FOR FAST TRAINS IN RELATION TO THE RISE IN SPEED

The cast iron brake block can be retained up to 200 km/h by a suitable arrangement of the signalling. In the field of the very high speeds, 250/300 km/h, it is necessary to resort to the combined systems. The test results of the electromagnetic brake up to 270 kmh are shown. Due to the frequent need for braking in high speed travel electrical control of braking will necessarily replace air brakes. A combined disc-cast iron block brake system was tested at 250 km/h and results are discussed. Hydraulic brakes and Foucault current brakes are considered.
