TfL Ref: 0057-2425

Thank you for your request received by Transport for London (TfL) on 6 April 2024 asking for information about Elizabeth line unit 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 for the Final release of the December 2023 - June 2024 Elizabeth Line Daily Unit Diagrams.


I can confirm that we hold the information you require. However, I am afraid that the information is exempt from release under sections 38 (Health and Safety) and 43 (Commercial Interests) of the Freedom of Information Act. The rationale for this is explained in full in the response to a previous, similar case that can be seen on the FOI pages of our website via the following link:

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

Yours sincerely,
