Case study
System integration for the GWR Security Operations Centre, providing LAN infrastructure, integrating a Barco video wall and CTRL platform, and upgrading the video management system.

TDM acted as system integrator for the new Security Operations Centre (SOC) of GWR in Swindon, the purpose-built replacement for its previous CCTV suite.
The previous suite had no integration between systems. CCTV, live train information and operational data sat on separate screens, and operators switched between devices to build a picture of an incident. The security and resilience team needed one platform, available at every operator position and on the video wall, that brought every source together.
The video management system (VMS) ran on outdated hardware and obsolete hosting, and had to be replaced in the same project.
TDM assessed the requirement and recommended Barco technology, supported by a live demonstration at Barco’s Customer Experience Centre in Bracknell. The project progressed from a temporary screen installation in September 2025 to a fully integrated control room in 2026. TDM coordinated between Barco and the security and resilience team throughout.
Operators see every source from one platform, on the wall or at their own position. The compositions put the relevant sources on screen for an event or incident without manual searching. The platform grows by adding encoders or decoders.
