Nexus Completes £8.8m Digital Upgrade of the Metro Control Room
A new SCADA system lets engineers spot faults in power, lifts, lighting and tunnel pumps faster, before they affect passengers.
- Nexus has replaced the Metro’s Supervisory Control and Data Acquisition system.
- The £8.8m project was delivered by Sella Controls during live operations.
- It is the biggest control room improvement since computerised signalling arrived in 2018.
Metro operator Nexus has completed an £8.8m overhaul of the control room systems that monitor and manage key parts of the network.
What has changed
The project replaced the Metro’s Supervisory Control and Data Acquisition (SCADA) system, which oversees power supplies, alarms, lifts, escalators, lighting and tunnel drainage pumps.
The new technology lets engineers and control teams find faults more quickly and respond before problems reach passengers. The control room itself has been redesigned, with more space and a new four-metre display for monitoring the power network.
Delivered around live services
Sella Controls carried out the work on behalf of Nexus while the Metro kept running. Nexus says it is the most significant control room upgrade since a computerised signalling control system was installed in 2018.
Major projects director Paul Welford called it “a vital investment in Metro’s long-term future”.
