TfL Ref: 0772-1819

Thank you for your email received by us on 22 June 2018 asking for information about London Underground’s Metropolitan line.

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:

How many signal failures have there been on met line in 2018? I’d like breakdown by month and whether the failures were at peak or off peak times

Please see the following table for the requested information from January 2018 to 23 June 2018.

Month Incidents (Peak in Brackets)    Percentage of Incidents at Peak Times
January                          16 (3)                                      19%
February                        22 (5)                                      23%
March                            29 (9)                                      31%
April                              30 (10)                                     33%
May                               23 (10)                                     43%
June (1st - 23rd)           13 (2)                                       15%
Total                             133 (39)                                    29%

As mentioned in our previous response to you about signalling incidents on the Metropolitan line (ref:0151-1819), 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.

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.
