What type of air brake test is required when adding cars not previously tested to your train?

When adding cars that have not been previously tested to your train, a Class 1 Air Brake Test, also known as the Initial Terminal Inspection, is required. This test is designed to ensure that all new cars added to the train meet the necessary standards for safe operation.

During a Class 1 Air Brake Test, thorough inspections are conducted to verify that the air brake systems on the newly added cars are functioning correctly. This includes checking for proper pressure, verifying that the brake pipes are intact, and ensuring that all components of the brake system are in good working order. The purpose of this inspection is crucial for the safety of the train, the crew, and all those who may be affected by its operation.

This requirement is in line with operational guidelines aimed at maintaining high safety standards in railroad operations. By conducting this test, crews can confirm that any additional cars will operate effectively within the current train configuration, thus ensuring reliability and safety during transit.
