TfL Ref: 0819-1819

Thank you for your email received by us on 26 June 2018 asking for audio recordings of the doors opening and closing in relation to our transport services.

Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and our information access policy.. You asked for:

sound files of both the door opening beeps and the door closing beeps of all stocks:

• Class 172 (London Overground)
• Class 315 (London Overground and TFL Rail) • Class 317 (London Overground) • Class 321 (London Overground) • Class 345 (TFL Rail) • Class 360 (TFL Rail) • Class 378 (London Overground) • S Stock (London Underground) • 1972 Stock (London Underground) • 1973 Stock (London Underground) • 1992 Stock (London Underground) • 1995 Stock (London Underground) • 1996 Stock (London Underground) • 2009 Stock (London Underground) • Bombardier CR4000 (Croydon Tram) • Stadler Variobahn (Croydon Tram) • B07 Stock (DLR) • B2K Stock (DLR) • B90 Stock (DLR) • B92 Stock (DLR) • Buses (All Makes And Models) • Cable Car

Please note that we are refusing your request under section 14(1) of the Act. This is because we are unable to provide these audio recordings without an exhaustive search across all of our modes to determine where they are held because these sound files are not held centrally. It may also require the manual reviewing of several individual contracts under which these recordings are provided to ascertain whether this is permissible within the agreements in place.

This is information in which there is very limited public interest but would require significant resource to locate, extract and collate the information you have requested. Whilst transparency is a vital part of our work, we consider that to undertake the necessary time needed to locate, review and extract the information needed for these audio recordings as required for the purposes of public release to answer your request would place an unreasonable burden on our resources.

Our principal duty is to provide an effective transport service for London and we consider that answering this request would require disproportionate effort to the benefit of providing it. Processing the request would be a significant distraction from our work managing the TfL network, requiring re-allocation of already limited resources and placing an unacceptable burden on a small number of personnel. We do wish to clarify that whilst we consider that your request falls under section 14(1) of the FOI Act, this does not reflect a conclusion that it has been your intention to deliberately place an undue burden on our resources.

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

Yours sincerely
