Rigid Overhead Conductor-rail System (ROCS)
Rigid Overhead Conductor-rail System (ROCS) uses a rigid conductor instead of a flexible wire for electric power collection. ROCS has a rigid conductor rail installed overhead. A copper contact wire is inserted in the conductor rail and the Pantograph on the rolling stock collects power from this rigid conductor. The rigid overhead conductor is a piece of Aluminium rail which is fixed to the tunnel ceiling with the help of a cantilever arrangement. This Al. rail is manufactured in 10 to 12 metre long pieces and then these pieces are joined together to form a continuous conductor all along the railway track. Contact wire is inserted into the groove of these aluminium rails so that the contact of the pantograph remains with the copper contact wire.

Contact wire is inserted into the groove of these aluminium rails so that the contact of the pantograph remains with the copper contact wire.
Rigid Overhead Conductor Rail (ROCR) is an alternative distribution system to conventional catenary systems in rail transit. Its characteristics make it the most applicable for fixed infrastructure feature, such as tunnels, bridges and maintenance depots, although its lower maintenance costs justify its installation in a wide range of environments.
A Rigid Overhead Conductor-rail System (ROCS) should be generally used in following cases:
Normally in tunnels of length more than 750m or where the provision of ATD is difficult.
Where the head room/height of the tunnel is not sufficient for conventional OHE.
Stations/Any other location for improved electrical clearances
RRCS (Retractable Rigid Conductor-Rail System) can be used in Maintenance Depots, Coal sidings/other sidings for overhead loading under SILO in electrified territory and container handling tracks.
Conventional OHE requires substantial space above the train under the overhead structure to maintain Electrical clearance from 25kV live conductor.
