Retractable Catenary

Pandrol’s Retractable Catenary is a clever removable rigid catenary system designed to ease and secure maintenance operations on rolling stocks.

The option to retract the overhead catenary system allows for safe maintenance and free access to the vehicle roof, creating space and allowing the train to be lifted for bogie inspection and maintenance.

Designed for any rolling stock equipped with pantograph, our safe system interlocks with a range of existing maintenance depot equipment, including disconnectors, walkways, bridge-cranes, doors, signalling equipment and lifting platforms.

Technical Features

  • The rigid catenary is made up of aluminium bars, assembled with junction clamps (splices).
  • The swivelling arms enable the simple and safe retraction of the catenary. In the standard version, the steel arms are available in lengths of up to 6m and installed maximum every 12m. Motorised and mechanical options are available.
  • The catenary can be retracted to create a safe, free space above the vehicle. This enables the vehicle to be lifted, facilitating bogie maintenance or safe access to the roof.
  • The system is operated using a control panel with three user levels, a touch panel, buttons, and installation, operation/maintenance indicators.


  • Unlike traditional rigid catenary, Pandrol’s Retractable Catenary allows free access to the train roof, enabling a full range of maintenance operations.
  • The system is extremely safe to use thanks to safety features such as an emergency stop, alarm and maximum usage controls.
  • The easy-to-use control panel enables the quick, efficient retraction of the catenary, saving time and labour costs by increasing ease of maintenance.
  • The aluminium and steel components and simplicity of Pandrol’s Retractable Catenary make it easy to maintain.
