What is the braking system of the train?

The train itself has great self-weight and adhesion. As long as the traction is not greater than the adhesion, it will be fine, so the slide rail can go, but it will easily slip (idle) if there is oil or water on it. The track is smooth, and the resistance is small when the car has speed. Without traction, it can use the kinetic energy of the locomotive to go far. \x0d\ The train adopts air braking, and there are two air compressors on the locomotive. Air is compressed into the main air cylinder of the locomotive for standby, and the locomotive is connected with the braking system of the vehicle behind it through an air pipeline, and the locomotive controls the charging and discharging of the train pipeline to control the braking of the train. Generally speaking, the train inflates and exhausts (relieving is a term, as opposed to braking), but this is not the case. \x0d\ For the sake of safety, charging and exhaust braking are adopted in our country, because it's nothing if the train can't move. But if we can't stop, we'll be in trouble. For example, the air pump is not pumping, and the train pipeline is broken. There is an auxiliary cylinder on the vehicle. After the locomotive/vehicle is connected, the locomotive controls to inflate the train pipe. First, the auxiliary cylinder is a miser who can't get in or out. When the pressure of the train pipe and the auxiliary air cylinder is the same, the pressure of the train pipe and the auxiliary air cylinder appears. The pressure of the auxiliary cylinder pushes the vehicle braking system to rub the wheel tread to generate braking force. When it is released, the train pipe is filled with air, and the pressure becomes greater, so the braking system will stay away from the wheel collapse surface until the pressure on both sides reaches equilibrium. \x0d\ Brake shoe used for vehicle braking, a bent iron block, is very heavy, and now there are also high-friction brake shoes, which are very light. Brakes generate braking force by rubbing against wheels. \ x0d \ It is a system installed on the locomotive, which changes the motor to generate torque for the generator to slow down. But you can only slow down, you can't stop, you still have to rely on the air brake. When the locomotive is towed, the traction comes from six traction motors, and when it is electrified, it will produce traction. When the train has great inertia, when it slows down, it turns the motor into a generator, and the rotor cuts the magnetic field lines to generate electric energy, while the magnetic field also produces the opposite force on the rotor, which is the braking force of resistance braking.
