BRAKING OF HIGH SPEED PASSENGER TRAINS

Passenger trains operating at maximum speeds of between 200 and 300 km/h must be equipped with brake gear that is highly efficient, operates reliably and is not too complex. Dynamic brakes are primarily suited for motor vehicles, while trailer stock is predominantly fitted with disc brakes. The use of additional adhesion-independent braking systems is recommended to ensure that prescribed braking distances are maintained even in very adverse weather conditions, and to facilitate rapid stopping in case of danger. Sophisticated anti-skid protection devices are invaluable aids for safe braking when adhesion is low. For practical purposes, high-speed passenger trains are equipped with an automatic air brake. Electromagnetic control of the air brake can improve the braking characteristics still further.
