British Transport Police has expanded its live facial recognition trial into London Underground stations, extending a six-month evaluation that began at selected transport hubs in the capital.
The force uses a camera to scan faces in a defined area and compare them with a watchlist prepared for the deployment. When the system produces a possible match, an officer reviews the alert and decides whether there is a basis to approach the person.
BTP describes the deployments as intelligence-led, meaning locations and watchlists are selected according to an identified policing purpose rather than operating as a permanent network across the Underground. The force has not presented the expansion as continuous facial recognition at every station.
Moving into Underground stations nevertheless places the technology in some of London’s busiest pedestrian environments. The network carries large volumes of passengers through constrained entrances, ticket halls and platforms, creating different operational conditions from an open-air deployment or a mainline rail concourse.
The original trial was introduced to assess whether live facial recognition could help identify people wanted by police or considered a risk to public safety. BTP said officers would remain responsible for decisions following an alert and that people who did not match the watchlist would not be stopped solely because they passed the camera.
The expansion forms part of wider growth in British police use of the technology. The UK government recently funded a fivefold increase in the national LFR vehicle fleet, supporting deployments by forces outside London as well as established Metropolitan Police operations.
That rollout is proceeding while the legal basis for police facial recognition remains contested. A High Court challenge to Metropolitan Police use of LFR is examining issues including watchlist criteria, proportionality and safeguards for people whose faces are scanned.
BTP’s trial will provide evidence from a transport-specific setting, where the force is responsible for rail passengers, staff and infrastructure.
