Railway Power Supply Dispatching The picture on the left shows the OCS disconnection being restored after an accident. When the blackout occurs due to OCS equipment failure, railway transportation will be directly interrupted, which requires immediate repair to restore the OCS and resume power supply. Railway Power Supply Dispatching The picture on the left shows maintenance and adjustment of the equipment in the control room of a traction substation.
