Braking systems of trains

Locomotives in the train must have a compressor type CT, with double-header allowed to use the E-500 compressors if they are working on a system of many units. This requirement follows from the possibility of significant costs of compressed air leaks, which must be achieved, without overload and increased heating compressors.

Prepare such trains are usually in the two formulations in different ways with their subsequent connection; battery brake pressure of the network must be higher than 4.0 kg / cm 2, the same pressure in the brake line should have a shunting locomotive.

In each of the compounds tested produced full avtotormozov. After the unification of the compositions and charge for at least 15 minutes inhibitory network check its density and pressure in the brake line of the tail wagon trains formed and operates the abbreviated testing. If the number of axes 450 to 480 minimum allowable time to reduce pressure on the 0.5 kg / cm 2 in the main tank locomotives, relative to their volume in thousands of liters, should not be less than 11 seconds, and the pressure in the brake line tail carriage - at least 3 , 5 kgf/cm2. Charging pressure in the brake line of the locomotive should be 4,8-5,0 kg/cm2. With reduced sampling the pressure in the brake line to reduce 0,5-0,6 kg/cm2, braking and vacation checks on the five caudal compartments.

In connection with high performance brake means trains with trains of empty wagons first step of inhibition in the route operates at reduced pressure equalized tank crane driver at 0,3-0,4 kg/cm2; validation of avtotormozov en route this stage is kept for 8-10 s, after which vacation. Avtotormoza released from over-pressure in the surge chamber I handle the situation of the crane to 6,0-6,5 kg / cm 2 and the subsequent transfer it to the Onboard position.

At stage reducing the pressure in the brake line more than 0,5 kg / cm 2 after the transition to the normal charging pressure to re-inflate the pressure in the brake line (surge chamber) to 6.0 kgf/cm2.

Driving a train with empty trains 400-480 long axes are allowed in areas that are downhill slope to 0.012, inclusive, after the development of local regulations and experienced with travel avtotormozov checking the operation of compressors and locomotives.
