Thank you for your request received by Transport for London (TfL) on 16 September 2024 asking for information about the Elizabeth line.

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. You asked:

Under the freedom of information act, I would like to have written confirmation of the disruption experienced by the Woolwich - Heathrow route of the Elizabeth Line, on July 24th, 2024.

From the twitter account, I can see a 'Sever Delays' alert at 6:52 am and a 'Minor Delays' alert at 8:56 am. May I have written confirmation of this? including start and end time of the service disruption.

05.05 - Incident commenced from the start of the service, with no trains operating between Paddington and Abbey Wood. This was due to a power supply issue and late finish of engineering works. Contingency plan agreed and implemented.

06.09 – Power Supply issue resolved. Service recovery commenced.

06.45 – Severe delays declared between Abbey Wood and Paddington, with Minor Delays for the remainder of the line.

07.45 – Severe delays declared between Abbey Wood and Heathrow via Paddington, with Minor Delays for the remainder of the line.

08.01 – Severe delays declared between Paddington and Heathrow, with Minor Delays for the remainder of the line.

08.52 – Minor Delays declared between Paddington and Heathrow / Reading, with a Good Service on the rest of the line
