Thank you for your email of 31 July 2008 asking for either old or current Duty Books for the Waterloo & City and Central lines.

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. However, in accordance with the FOI Act we are not obliged to supply the information as it is subject to a statutory exemption to the right of access to information under section 38(1) health and safety.

Our approach to the disclosure of this information has changed following a security review.

In this instance the exemption has been applied as disclosure of the information you have requested would be likely to endanger the safety of an individual. The use of this exemption in relation to similar information was considered by the Information Commissioner in Decision Notice FS50607218, which was issued on 17 March 2016. The Commissioner upheld both the application of the exemption and the balance of the public interest. We consider the same arguments apply to your request.

Whilst we appreciate that these are for personal use, any disclosure under FOI must be considered as a disclosure to the world at large. TfL now publish anonymised responses to FOI requests on our website.

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

Yours sincerely

Jasmine Howard
