Catenary maintenance vehicle

Railroad overhead lines must be suspended high enough to allow a sufficient loading gauge for trains to travel beneath them safely.

Additionally, a specialized vehicle is required to minimize the risk of electric shock when working with overhead wires which are operated at voltages which can be fatal to humans.

To assist workers in their duties, catenary maintenance vehicles normally include an interior workshop and storage space, along with basic crew amenities such as bathrooms and a kitchen.

[2] While catenary maintenance vehicles normally conduct planned inspections and repairs, they are vital in the event of damage or disruption to the overhead wires that provide power to electric trains.

[8] While primarily designed for working with overhead wires, these vehicles can also be used to inspect bridges and tunnels along the railroad.
