During a pre-departure test, which safety checks are included?

• A. Only brake tests.
• B. Run a test on ticketing.
• C. Brake tests, door checks, all safety devices functioning, and communication systems tested.
• D. Crew attendance.

Answer: (C)

Before departure, trains must be verified for safety by a comprehensive set of checks on critical systems. The brakes are tested to confirm reliable stopping and correct functioning of the braking system. Doors are checked to ensure they open and close properly and won’t trap passengers. All safety devices—such as interlocks, emergency systems, signaling and protection features—must be functioning to prevent unsafe operations. And the communication systems are tested so the crew can coordinate with control and convey information to passengers if needed. This full package is necessary because focusing on just one area, like brakes, leaves other vital safety elements unchecked. Ticketing or crew attendance aren’t safety-system checks, so they don’t fulfill the pre-departure safety requirement. Therefore, the best choice is the option that includes brake tests, door checks, all safety devices functioning, and communication systems tested.
