Checking the efficiency and responsiveness of the brakes

Functionality testing of the train's air brake system primarily involves checking the efficiency and responsiveness of the brakes. This process ensures that the braking system operates correctly and reliably under various conditions. By assessing how well the brakes respond when engaged, it is possible to identify any issues that could affect safety during operation.

During functionality testing, personnel will perform various assessments such as measuring the air pressure in the brake system, inspecting the functionality of the brake valves, and sometimes simulating different stopping scenarios to confirm that the brakes engage smoothly and effectively. The ultimate goal is to verify that the braking system can stop the train within a safe distance and in a controlled manner, which is crucial for both passenger safety and cargo protection.
