Brake trains

In the passenger and freight trains up to 350 axes leave automatic brakes produce train crane operator handles the situation. Holiday train position ensures high reliability vacation route using I status. However, freight trains longer than 350 axes in the train leave the pen position crane driver's rate of increase of pressure in the line tail of the train may not be sufficient to move to the vacation position of main piston air distributors № 270-002, with insufficient density of the rings, and diaphragms air distributors № 270 -005, in which the line communicated with the cutoff camera through a hole in the plunger diameter, 0.3 mm (to move the main diaphragm is required rate of increase of pressure more than 0.1 kgf/cm2 for 20 s). Therefore, in freight trains with a number of axes more than 350 brake released when testing using the handle I tap and inflated the line pressure at 0.5 kg/cm2 above charger (with holding pens in the I position to a corresponding increase in surge chamber pressure). In such trains at a charging pressure of 5,3-5,5 kg/cm2 on the way brakes are released from the restraint pen crane driver in the I position until the pressure equalized tank 5,8-6,0 kg/cm2, and at a charging pressure 6,0-6,2 kg/cm2 (at the weight of more than 6 thousand tons) - up to pressure 6,5-6,8 kg/cm2. This ensures a reliable and leave en route.
