TfL Ref: 3596-2324

Thank you for your request received by Transport for London (TfL) on 4 January 2024 asking for information about CCTV on Central line trains.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.  I can confirm that we hold the information you require. You asked:  When was CCTV installed on Central Line trains - that is - Does CCTV operate in every car (carriage) on the Central Line on the TFL network. Please note - I do not mean stations or platforms that are served by the Central Line (The Red One) I mean the actual moving parts - the trains

I can confirm we do hold this information. However, in accordance with the FOI Act we are not obliged to supply this detail as it is subject to statutory exemptions to the right of access to information under section 24 (National security), Section 31(1)(a) (Prevention and detection of crime) which relates to information whose disclosure would be likely to prejudice the apprehension or prosecution of offenders, Section 31(1)(g), which relates to information whose disclosure would be likely to prejudice the exercise by any public authority of its functions or any of the purpose of ascertaining whether any person has failed to comply with the law, and finally Section 38(1)(b) of the Act which relates to the Health and safety of individuals.

Disclosing any information pertaining to the extent of our CCTV coverage could be compromised by individuals wishing to exploit security vulnerabilities to harm our network, to cause harm to members of the public using our services and / or to commit crime.

The London transport system is a critical piece of national infrastructure used by millions of passengers every day, and as such we employ rigorous safeguards to protect it from security attack and to protect our customers and staff. Like other organisations we are subject to regular attempted security issues and issues with crime and anti social behaviour. Disclosure of this information has to be regarded as a disclosure to ‘the public at large’. Whilst we make no suggestion that you would use this information for anything other than you own personal interest, this information if disclosed could potentially be obtained and utilised by individuals who may wish to use this information to cause disruption or harm to the London Underground network. Additionally disclosure of information which could compromise security and safety preparedness on London Underground’s network would place members of the public and TfL staff at risk by highlighting areas on the network which could be susceptible to being targeted by criminals. Essentially, we consider that releasing the requested information would be likely to prejudice our efforts to prevent and detect future attacks and undermine our ability to safeguard the network and the safety of our passengers and staff.

The use of these exemptions is subject to an assessment of the public interest in relation to the disclosure of the information concerned. TfL recognises the need for openness and transparency by public authorities, but in this instance the public interest in applying the exemptions, in order to minimise risks to operational resilience, safe operation of the London Underground network, the welfare of staff and members of the general public, and to act as a deterrent to criminal behaviour outweighs the public interest in disclosure.

This principle has been previously agreed by the Information Commissioner in relation to a similar, previous request, as can be seen in the following Decision Notice - the same arguments apply in your case: https://ico.org.uk/media/action-weve-taken/decision-notices/2017/2013536/fs50633090.pdf

Please see the attached information sheet for details of your right to appeal.

Yours sincerely
