TfL Ref: FOI-1472-1718

Thank you for your email received by us on 14 September 2017 asking for information about the number of delays on the London Underground network between 1 September 2016 and 1 September 2017. I apologise for the delay in responding.

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 hold the information you require. You asked for the following:

Between the 1st September 2016 and 1st September 2017, the number of days on which there were (a) severe delays; and (b) severe or minor delays on the following lines:

Bakerloo, Central, Circle, District, Hammersmith and City, Jubilee, Metropolitan, Northern, Piccadilly, Victoria, Waterloo and City

The Tube supports nearly five million customer journeys per day. In 2016/17 a total of 1.38 billion passenger journeys were made and our transport network carried more passengers than ever before.

We are committed to improving the services we provide; network delays are down with reliability improved. As part of our ongoing investment in the Underground network and to meet the needs of London's rapidly growing population, we continue to invest in and improve our services. For example, by introducing new modern signalling systems and new trains on the Piccadilly, Bakerloo, Central and Waterloo & City lines, delays due to signal and train failures will be reduced and help increase capacity to help meet London’s growing demand. Over the course of time we will also be introducing platform edge doors where possible, as used on the Jubilee line, helping to ensure customer safety and reducing delays caused by litter and other obstructions on the tracks.

Attached is the requested data. Please note that whilst there are a total of five days with no reported delays during the requested period, if a minor delay occurs briefly on a small section of line, this will impact on overall daily reported figures. For example, on 23 September 2016, the Northern line was the only service which advertised a delay message as it was suspended between Finchley Central and Mill Hill East between 13.43 and 14.39. Whilst a relatively small number of customers were affected for a relatively short time and the rest of the Northern line network offered a good service all day, the entire line is counted as having had a delay during that day.

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
