When moving a High Speed Trainset dead in tow, which interfaces must be connected between the locomotive and the trainset?

• A. Main reservoir and brake pipe must be coupled; 480V cables connected; pantographs down.
• B. Pantographs up; no cable connections.
• C. Only the pantographs.
• D. Only the brake pipe.

Answer: (A)

When moving a High Speed Trainset dead in tow, you must keep control of the train’s braking and isolate the train from the overhead electrical supply. Connecting the main reservoir and brake pipe between the locomotive and the trainset allows the locomotive to charge the train’s air system and apply or release the brakes as needed, so you can safely slow or stop the train if required. Supplying the trainset with the 480V cables ensures essential electrical power is available for systems that must remain powered during towing. Keeping the pantographs down prevents accidental energization or contact with the overhead lines, protecting equipment and personnel since the trainset is not being powered by the locomotive. Taken together, these interfaces provide safe control of braking, maintain necessary electrical power, and prevent overhead-line risks during dead-in-tow movement.
