Hi, may I please have the station floor plan for each station of the DLR, Overground, TFL Rail, and Underground? Thank you for your help in advance.

Our ref: FOI-0966-1920/GH

Thank you for your request received by Transport for London (TfL) on 3 July 2019 asking for station floor plans for each station of the DLR, Overground, TFL Rail, and Underground.

Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy.

I can confirm that we do hold the information you require. However, to provide the information you have requested would exceed the ‘appropriate limit’ of £450 set by the Freedom of Information (Appropriate Limit and Fees) Regulations 2004.

Under section 12 of the FOI Act, we are not obliged to comply with requests if we estimate that the cost of determining whether we hold the information, locating and retrieving it and extracting it from other information would exceed the appropriate limit. In this instance, we estimate that the time required to answer your request would exceed 18 hours which, at £25 per hour (the rate stipulated by the Regulations), exceeds the ‘appropriate limit’.

You have asked for the station floor plan for each station of the DLR, Overground, TFL Rail, and Underground. As there are over 400 stations covered by your request, identifying whether a station plan exists, then locating and collating the information would easily exceed the appropriate limit.

Whilst you may wish to consider refining your request to specific stations, if the cost of responding to your request was within the £450 limit, we would still need to consider whether the information contained in any station plans could be utilised by individuals who may wish to use this information to cause disruption or harm to the London Underground network. The London Underground system is an attractive terrorist target for several reasons including, its importance to London and the knock on effect to the nation’s economy if it is disrupted, the publicity gained from attacking an iconic transport system and the attractiveness of the system for a mass casualty attack due to its open, mass transport nature. It is also part of the nation’s critical infrastructure by virtue of its central importance to the functioning of London and its economy.

Whilst we make no suggestion that you would use this information for anything other than you own personal interest, disclosure of this information to you has to be regarded as a disclosure to ‘the public at large’, and we would therefore need to consider whether an exemption would apply to releasing any individual station plans requested.

If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.

Yours sincerely

Graham Hurt
