The Rigid catenary system is composed by an aluminum alloy profile where it is fixed a copper contact wire, allowing the current collection through a pantograph.

This profile is not working with mechanical tension, and it is hold by metallic supports and insulators in the tunnels, or by masts outside tunnels.

On depots and maintenance facilities, where it is necessary to make the maintenance works on train roof and on bogies, it is necessary a moveable catenary, that allows the free access to the train work zones. This is done by using a retractable rigid catenary that it’s supported on swiveling arms, that allows the trains to move inside and outside maintenance tracks under catenary power, and allows the access to the work zones once the catenary is retracted from the electrical supply position.
