Catenary maintenance vehicle

An Amtrak catenary maintenance vehicle. Both a crane and a movable platform can be seen on the vehicle's roof.

A catenary maintenance vehicle (also known as a tower wagon or tower car) is a railroad maintenance of way vehicle that is used to maintain and inspect overhead line (also known as catenary) on electrified railroad or metro tracks.[1][2] Such vehicles are typically self-propelled by a diesel engine, to allow them to operate when power is shut off to the overhead lines for worker safety or in the event of a power failure.[3] Catenary maintenance vehicles allow maintenance of way workers to safely work on overhead wires and typically include a crane to install or remove wires as needed.
