TfL Ref: FOI-2788-2324

Thank you for your request received by Transport for London (TfL) on 3 November 2023 asking for information about departure times for the Piccadilly and Elizabeth 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 that we do hold the information you require.

Please see the requested information in the files attached.  

For the Elizabeth line data, please note that, on 3 November 2023, there were two axle counter failures (failure of part of the signalling system) at Heathrow Airport Junction on the Great Western Mainline between Paddington and Reading. This had a significant impact on the service, and as a result, a number of the Heathrow services were disrupted and/or cancelled.

If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely,

Mary Abidakun
FOI Case Officer
