We answered
TfL Ref: FOI-3838-2324
Thank you for your request received by Transport for London (TfL) on 24th January 2024 asking for Northern Line vertical diagrams. Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.
Specifically you asked:
“Northern Line vertical diagrams: Hello, I would like to have access to ALL of the vertical line diagrams at EVERY station please. I am making a project for a game and need them.”
I can confirm that we hold the information you require. However, I am afraid that to source all of the information within the scope of your request would exceed the costs limit for responding to FOI cases, as set out under section 12 of the Freedom of Information Act. Under section 12 TfL is not required to provide information if it would cost more than £450 to determine if that information is held, and to the locate, retrieve or extract it from elsewhere. This is calculated at a rate of £25 per hour, equivalent to 18 hours work.
The exemption applies in this instance given the amount of information that falls within the scope of your request. There are 52 stations on the Northern Line and two such diagrams for most stations, meaning there are over 100 such diagrams that we would need to source. Colleagues in our Customer Information and Design team estimate it would take well in excess of the 18 hour limit to find all of the current versions, which are stored across multiple different files.
In order to bring your request within the costs limit you may wish to narrow its scope – for example, by restricting it to a select number of stations only. However, please note, release of information under FOI does not mean that copyright laws do not apply to that material. Access would be provided for personal use only with permission not granted for any re-production or re-use.
Please see the attached information sheet for details of your right to appeal.
Yours sincerely,
David Wells FOI Case Officer FOI Case Management Team General Counsel Transport for London
