A block of cars are set-out from a train. After returning to the train, is an Application and Release test required before proceeding?

• A. Yes
• B. No
• C. Only if a brake test was performed
• D. Only if the set-out caused a change in locomotive count

Answer: (A)

The test is required because reconfiguring the train after cars are set-out and then rejoined changes the train’s makeup. When cars are added back, the braking system, brake pipe continuity, and the overall train authority must be re-verified with the current consist to ensure the train will respond correctly to brake commands and that the locomotive count and car identities are correct. This reverification helps catch any issues caused by the reconstitution that could affect safety or performance, even if no brake test was done during the set-out or if the locomotive count happened to remain the same. Therefore, proceed only after performing the Application and Release test to confirm the train is ready for movement.
