Thank you for your email received by us on 15 February 2017 asking for copies of the source files in relation to the digital images of London Underground tunnelling for the purposes of your project work.
Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. I can confirm we do hold the information you require.
The information requested is subject to a statutory exemption to the right of access to information, under Section 38(1)(b) of the Act. In this instance the exemption has been applied as disclosure of the information requested would be likely to adversely affect the safety and security of TfL employees and members of the general public.
Whilst we make no suggestion that you would use this information for anything other than your own personal interests, disclosure of this information to you has to be regarded as a disclosure to ‘the public at large’. This information could potentially be obtained and utilised by individuals who may wish to use this detailed level technical 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.
The use of this exemption 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 exemption, 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, outweighs the public interest in disclosure.
I am sorry that my reply is a disappointing one in this instance.
If this is not the information you are looking for, or if you are unable to access it for some reason, please feel free to contact me.
Please see the attached information sheet for details of your right to appeal.

Dear Jasmine,
Many thanks for your response.
The information you have provided is very useful and will greatly inform and benefit my project. The images I have screens hotted below seem to have been generated from a 3 Dimensional model or some digital drawing software. I am just wondering whether you would be able to gain access to any of these files and whether they would be available for me to use.
Any information you could share on this would be greatly appreciated,
