Air distributors and electric air distributors that work unsatisfactorily should be replaced with serviceable ones;

Anti-skid device action (if equipped). To check the mechanical anti-skid device, it is necessary to turn the inertial weight through the window in the sensor housing after complete service braking. In this case, air must be released from the brake cylinder of the tested bogie through the relief valve. After the impact on the load has ceased, it should return to its original position by itself, and the brake cylinder should be filled with compressed air to the initial pressure, which is controlled by a pressure gauge on the side wall of the car body. The test must be carried out for each sensor.

To check the electronic anti-skid device, after a full service brake has been performed, it is necessary to check the operation of the relief valves by running a test program. In this case, there should be a sequential discharge of air on the corresponding wheelset and the operation of the corresponding pressure indicators compressed air this axle on board the car;

Speed ​​governor action (if equipped). To check, it is necessary to press the button for checking the high-speed regulator after a complete service braking.

When using other types of automatic regulators, the minimum length of the regulating element of the automatic regulator when leaving the point of formation and turnover and when checking at intermediate points of technical inspection must be indicated in the operating manual for a specific car model.

The angles of inclination of the horizontal and vertical levers must ensure the normal operation of the linkage to the limit of wear of the brake pads. In the released state of the brake, the leading horizontal lever (horizontal lever on the side of the brake cylinder rod) must be inclined towards the bogie;

Brake cylinder outlets, which must be within the limits specified in Table III.1 of this Regulation.

2 The output of the brake cylinder rod with composite pads on passenger cars is indicated taking into account the length of the clamp (70 mm) installed on the rod.

3 The outlets of the brake cylinder rods for other types of cars are installed in accordance with the manual for their operation.

On passenger cars with disc brakes, additionally check:

The total clearance between both linings and the disc on each disc. The gap between both pads and the disc should be no more than 6 mm. On wagons equipped parking brakes, check clearances when releasing after emergency braking;

No air passage check valve on the pipeline between the brake line and the additional feed tank;

The condition of the friction surfaces of the discs (visually with the broach of the cars);

Brake standards for freight and passenger trains. The sequence of trains with missing brake pressure

All trains departing from the station must be provided with a single minimum pressure of the brake shoes (per 100 tf of weight of the train or train) in accordance with the standards for brakes approved by the Ministry of Railways (Appendix 2 of the Instruction for the Operation of Brakes of the Rolling Stock of Railways TsT-TsV-TsL- VNIIZhT \ 277; Appendix 1 to the Directive of the Ministry of Railways of Russia No. E-501u dated 03.27.01):

• freight loaded, freight trains empty with the number of axles more than 400 to 520 (inclusive) and refrigerated trains for speeds up to 90 km/h - 33 tf;
• empty cargo up to 350 axles for speeds up to 100 km/h - 55 tf;
• passenger train for speeds up to 120 km/h - 60 tf;
• refrigerated train for speeds over 90 to 100 km/h - 55 tf;
• refrigerated train for speeds over 100 to 120 km/h - 60 tf;
• freight-passenger train, empty freight train with the number of axles from 350 to 400 (inclusive) for speeds up to 90 km/h - 44 tf.

Passenger trains, in exceptional cases, in case of failure of the EPT along the route and the transition to pneumatic brakes, are allowed to proceed with a decrease in the maximum allowable speed (130, 140, 160 km/h) by 10 km/h.
Freight trains, which include wagons with an axle load of 21 tons and automatic brakes are all on, can run at a set speed:

• with a brake pressure of less than 33 tf, but not less than 31 tf per 100 tf of train weight and if the train contains at least 75% of cars equipped with composite brake pads, with air distributors switched on to the average mode;
• with a brake pressure of less than 31 tf, but not less than 30 tf per 100 tf of train weight and if the train contains at least 100% of cars equipped with composite brake pads, with air distributors switched on to the average mode.

Trains with a brake pressure of 100 tf less than the single smallest weight with the automatic brakes of all cars on, as well as when the brakes of individual cars are turned off along the way, are allowed to send and pass:

• freight and refrigerated trains moving at speeds up to 80 km/h, with a pressure of at least 28 tf per 100 tf of train weight;
• freight trains with an empty wagon train of up to 350 axles, moving at speeds of more than 90 to 100 km/h, with a load of at least 50 tf per 100 tf of train weight;
• passenger trains traveling at speeds up to 120 km/h, with a pressure of at least 45 tf per 100 tf of train weight;
• freight-passenger trains circulating at speeds up to 90 km/h, with a pressure of at least 38 tf per 100 tf of train weight;
• refrigerated trains moving at speeds of more than 90 to 120 km/h, with a pressure of at least 50 tf per 100 tf of train weight.

At the same time, the speed of a passenger train must be reduced by 1 km/h for each ton of missing brake pressure per 100 tf of weight on sections with a slope of less than 0.006, by 2 km/h for each ton of missing brake pressure per 100 tf of weight on sections with a slope of 0.006. The speed of movement of other trains must be reduced by 2 km/h for each ton of missing brake pressure per 100 tf of weight. The speed determined in this way, which is not a multiple of 5 km/h, shall be rounded up to a multiple of five, the nearest lower value. By the same amount, reduce the speed of traffic lights with yellow light.
In the event of a decrease in the braking pressure of trains less than the single smallest due to the switching off of faulty automatic brakes for individual cars along the way, it is allowed to let such trains go to the first station where there is a maintenance point (PTO) of cars.
In exceptional cases, due to the failure of automatic brakes for individual cars along the route, the train can be sent from an intermediate station to the first station where there is a maintenance of cars, with a brake pressure less than established by the standards, provided that there are slopes not steeper than 0.010 in this section, with the issuance to the driver speed limit warnings.
The order of departure and following of such trains is established by the order of the head of the road. The speed of movement of freight and refrigerator trains when pressed is less than 28 tf per 100 t of train weight, but not less than 25 t; of a passenger-and-freight train when pressing less than 38 tf per 100 t of train weight, but not less than 33 tf - should be no more than 55 km/h.
Departure of a freight or refrigerated train is prohibited when the brake pressure is less than 25 tf per 100 tf of weight, a freight-passenger train - less than 33 tf per 100 tf, and a passenger train - less than 45 tf per 100 tf. The repair of the brakes in the train is carried out by inspectors who are sent from the nearest maintenance department of the cars.
The calculated pressures of the brake shoes are indicated in the operating instructions for the brakes of the rolling stock of railways for cars in Table. 1, and for locomotives, multiple unit rolling stock and tenders in Table. 2 applications 2.
The actual weight of freight, mail and baggage cars in trains is determined according to train documents, the accounting weight of locomotives and the number of brake axles - according to Table. 3 apps 2.
The weight of passenger cars is determined according to the data printed on the body or channel of the cars, and the load from passengers, hand luggage and equipment is taken:

• for SV and soft cars for 20 seats- 2.0 tf per wagon;
• other soft - 3.0 tf, compartment - 4.0 tf;
• compartments with seats, non-compartment reserved seats and dining cars - 6.0 tf;
• for interregional carriages in fast and passenger trains - 7.0 tf; non-compartment non-reserved seats - 9.0 tf

The total braking pressure of the pads in a loaded freight train is determined by summing the pressures of the pads on each axle of all cars in the train, and for an empty passenger and freight train, the pressure of the locomotive is taken into account. In freight trains, the weight of the locomotive and its brake pressure are not taken into account, because its weight is no more than 10% of the weight of the train, and the pressing of the blocks is 100 tf of weight more than that of the wagons. However, on slopes of 0.020 or more, the weight and brake pressure of the locomotive are taken into account.
To keep in place after stopping on the stretch in the event of a malfunction of the auto brakes, freight, cargo-passenger and mail-luggage trains must have hand brakes and brake shoes in accordance with the standards specified in Table. 4 applications 2. If there are not enough hand brakes in the train, then they are replaced by brake shoes at the rate of one shoe for three brake axles with an axle load of 10 tf or more, or one shoe per axle when installed under a wagon with a lower axle load.

The order of placement and inclusion of automatic brakes in trains

Automatic brakes of all wagons in a train departing from a station where there is a wagon maintenance point, as well as from a train formation station or a mass loading point, must be switched on.
Disabling a serviceable wagon brake is possible only in cases provided for by the MPS. Moreover, there should be no more than eight axles in the train with the brakes turned off and a flying highway in one group, and in the tail of the train in front of the last two brake cars - no more than four axles.
In case of failure of the auto brakes of one of the two tail cars, shunting work is performed at the nearest station to place two cars with serviceable auto brakes in the tail of the train. In case of failure of the air distributor of the tail car of the electric train, it must be replaced at the nearest station by a serviceable air distributor of the neighboring car.
Passenger trains must be operated on electric pneumatic brakes, and if there are RIC-size cars in the composition - on pneumatic brakes. If a passenger train has one car with an KE air distributor, it can be turned off if the value of a single brake pressure is provided in accordance with the established standard. As an exception, it is allowed to attach no more than two passenger cars to the tail of a passenger train on an EPT that are not equipped with an EPT, but with a serviceable automatic brake.
Freight wagons are not allowed on passenger trains, except as provided for by the PTE. In freight and passenger-and-freight trains, the joint use of freight and passenger air distributors is allowed. passenger types. If in freight train no more than two passenger cars, then their air distributors can be turned off (except for two tail cars).
