Braking systems of trains

If cars in passenger trains equipped with dual skorodeystvuyuschimi triple valves, they are included in a car without an accelerator emergency brake. This condition is necessary to ensure smooth braking of the train and improve the level of the brake when braking. The fact that the triple valves are discharging extra performance brake line. Their operation, the braking at the initial time until the main piston is not cut off communication with the reservoir spare brake line, depends on the rate of discharge of the train brake pipe. Thus there is a significant release of compressed air from the spare tank in the back line. Particularly low rate in the tail of the train is obtained at low levels of inhibition. This leads to a retardation of the brakes in the rear cars, which causes the longitudinal response in the train. Shutting down half of the triple valve increases the smoothness of braking due to a smaller brake clicking on the train. Reduction of emission of air from the spare tank in the brake lines at the beginning of inhibition contributes to more rapid braked and also improves the smoothness of braking.
