What should be done after any repairs made to the braking system?

After any repairs are made to the braking system, performing a brake test is crucial to ensure that the system is functioning correctly and safely. Brake tests are an essential part of the safety protocols in rail operations because they verify that the repairs were effective and that the braking system can adequately respond in various conditions. This process helps identify any issues that may not have been apparent during the repair, ensuring the safety of the train, crew, and passengers.

While acknowledging the completion of repairs, updating the repair log, and inspecting the entire train are also important practices, they do not directly verify the operational integrity of the braking system. A brake test explicitly confirms that the repairs have successfully restored the necessary functionality of the brakes, which is paramount for safe railway operation.
