INNOVATIONS IN CONTINENTAL BRAKING PRACTICE

The article describes the addition of a quick-action valve to the "U" graduated-release distributor as designed by the Italian Westinghouse company of Turin (Westinghouse Freni e Segnali, Cia). The quick-action feature is the distributor proper gives a rapid drop in brake-pipe pressure all down the train for emergency application, ensuring that brakes apply fully almost in accordance with the timing of the distributor. For example, on a 20-coach train travelling at 140 km/h the stopping distance without quick-action was 940 meters. With quick-action, the stopping distance was 850 meters. A comment is made to the effect that if improvements in service braking and flexibility in release are to be made, the only logical way of achieving this is to incorporate "e.p. control" (electro-pneumatic control).
