What is the purpose of the air brake system?

The purpose of the air brake system is crucial for the safe operation of trains. It is specifically designed to slow down or stop the train by utilizing compressed air to apply brakes on the train’s wheels. This system operates by releasing air pressure in the lines, which then activates the brake cylinders that push brake shoes against the wheels. This interaction generates friction, ultimately leading to a reduction in speed or a complete halt of the train.

The air brake system is preferred in the railway industry due to its effectiveness and reliability. It allows for better control of large trains, which can carry significant weight, as well as providing the ability to apply braking force uniformly across all cars in a train. This is particularly important for maintaining safety, as trains can take longer distances to stop compared to other vehicles.

Understanding this function is essential for anyone training as a locomotive engineer, as proper handling of the air brake system directly affects the safety and efficiency of train operations.
