The Civia unit 465-261 is maneuvering at Mollet - Santa Rosa station to access the Alstom factory branch line in Santa Perpetua de Mogoda, where certain warranty points will be inspected.
The Alstom branch line lacks a departure signal and connects to the main track through a manually switched escape with a Bouré electric lock. Typically, the Granollers Canovellas factor is called upon to perform these maneuvers. Local clearance is required for someone to release the key and switch the escape. This is a centralized maneuver to enable it to bypass the departure signal and merge onto the main track. Unlike normal operations, the centralized maneuver is controlled by the Traffic or CTC Supervisor, allowing the train to move forward or backward. Once everything is completed, the centralized maneuver is removed, the switch is returned to its original position, the key is returned to the lock, the local clearance is withdrawn, and everything is ready.
