What air test is required after setting out cars if your train was given a Transfer Train Movement Air Test at origin?

• A. Conduct a full leakage test only.
• B. No air test is required.
• C. Determine brake pipe pressure in the rear is restored.
• D. Check main reservoir pressure only.

Answer: (C)

After rearranging the train by setting out cars, you must verify that the brake pipe pressure at the rear is restored. This ensures the entire train still has a charged and continuous air brake system, which is essential for safe braking when you resume movement. A Transfer Train Movement Air Test at origin checks for leaks and proper charging, but changing the train’s length can cause pressure changes toward the rear. Confirming that the rear brake pipe pressure is back to the required level guarantees the trailing portion will respond correctly to brake commands.

If the rear pressure isn’t restored, you’d recharge and recheck before continuing. This test specifically ensures air continuity to the rear; verifying only main reservoir pressure or performing a full leakage test isn’t the immediate requirement after a set-out.
