Which statement correctly describes the status indicated by a 'BP Test OK' message after a brake pipe test?

• A. The BP test completed successfully.
• B. The BP test failed and must be redone.
• C. The test detected a leak.
• D. The system is in standby mode.

Answer: (A)

Understanding brake pipe test results: a message reading “BP Test OK” means the brake pipe test has been completed and the results meet the required specs. In practical terms, the brake pipe pressure stayed within the acceptable range during the test and no leaks or faults were detected, so the system passes the test and is considered ready for operation. If there were a problem, you’d see an indication of failure or a leak, not an OK status; a standby state would reflect a different condition altogether.
