The OCC (Operations Control Centre)

The complex operation of the Metro is controlled and supervised from an Operations Control Centre (OCC) located at the Metro headquarters in a type of bunker protected from any incident such as floods, sabotage, accidents, etc.

This OCC has four basic functions:

• Train circulation control.
• Network power control.
• Control of fixed installations (escalators, lifts, etc.).
• Control of security and communications (with the closed circuit monitoring centre and detailed information).

Furthermore, all trains and stations are equipped with intercoms that communicate with the OCC by radio signal.

Below is a list of the systems featured by the Bilbao Metro Operations Centre:

Traffic Remote Control System.

This system is supported by traffic software that issues circulation orders and controls that they are observed.

Power Supply Remote Control.

This system controls and organises power supply, distinguishing between two types: power supplied for the trains and power supplied for installations.

Communications Remote Control.

This system controls communications. Two large communication areas have been established: internal communication, between the people responsible for operating the Metro, and communications with clients.
Communication is two way: communication from the control centre to employees and users and vice versa. Communication systems used are:

• Radio-Telephones: Communication between the Control Centre and the trains.
• Automatic Telephony: Immediate communication between all stations and services.
• Selective Telephony:This is an emergency telephone located at the end of the platforms and that communicates with the Control Centre.
• Public Address System.
• Intercoms.

Remote Control of Installations.

All Metro installations are automatic and centralised: station lighting, accesses, escalators, lifts, pumps, ventilation systems and fire detection systems.
It is important to explain that all installations have three control levels: at local level, at the installation itself; at station level and, finally, at Operations Control Centre level.

Remote Control of Ticket Dispensers.

Both the sale of tickets and access control to stations is performed automatically.
