What is the primary purpose of performing a Transfer Train Movement Air Test?

• A. To verify air brakes work on the moving train without performing a full train brake test
• B. To test the engine only
• C. To measure line clearance
• D. To check coupler alignment

Answer: (A)

The main idea behind a Transfer Train Movement Air Test is to quickly verify that the train’s air brake system responds properly while the train is moving. This lets the locomotive engineer confirm that brakes can be applied and released during a transfer run, ensuring the train can be slowed and stopped safely without having to perform a full, formal brake test each time. It’s a movement-focused safety check, not a test of the engine, not a measurement of line clearance, and not a coupler alignment check. If the brakes behave as expected during the motion, the transfer can proceed; if not, more thorough testing or maintenance is needed.
