What is a Deadman in LRV operation?

• A. A device used on LRVs which must be held in the operating position before movement can occur, and which will bring the LRV to a stop if released.
• B. A device that ensures doors close
• C. A device that activates the lights
• D. A device to interlock signals

Answer: (A)

A Deadman is a safety control that requires the operator to continuously hold it in the active position in order for the LRV to move. If the control is released, the system automatically brings the vehicle to a stop. This design ensures the operator remains actively engaged and able to respond, so if the operator becomes distracted or incapacitated, the train will not continue moving unsupervised. Devices for doors, lights, or signal interlocks serve different functions and do not govern movement by continuous activation, which is why they aren’t Deadman devices.
