TfL Ref: 0151-1819

Thank you for your email received by us on 18 April 2018 asking for information about service on London Underground’s Metropolitan line from October 2017 to April 2018

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:

The metropolitan line has been increasingly poor with signal failures and delays since around October 2017. I would like to know how many signal failures there have been month on month from October 2017 - April 2018 compared to October 2016 - April 2017

Under a major programme of modernisation, work has began in installing a state of the art signalling system across the Circle, Hammersmith & City, District and Metropolitan lines. This will allow us to run trains closer together and will see reliability, frequency and journey time improvements across all four lines by 2023. The combination of new S-Stock trains and the new signalling system will see capacity increases of 27% on the Metropolitan line and 33% across all four lines. Track and drainage improvements are also underway between Baker Street and Finchley Road as part of our works to boost efficiency on the network.

I can advise that there have been 127 incidents categorised as ‘signals’ recorded on our database between October 2016 and April 2017. During the same months and dates in 2017 to 2018 there was a total of 180 incidents as shown in the attached table.

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
