You asked

There is a District line service scheduled to depart from Westminster at 07.39 on weekdays. I would like to know 1) the percentage of this service that departs in time; and 2) on average how many minutes late does this service depart. If you could please supply the figures for the last calendar year from today’s date (07 March 2019).

We answered

Our ref: FOI-3329-1819/GH

Thank you for your request received by Transport for London (TfL) on 7 March 2019 asking for information about the performance of District line services.

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.

1) the percentage of this service that departs in time;

We do not record train punctuality as ‘on time’, however the attached spreadsheet shows the daily departure times for this service. The train service is a ‘turn up and go’ service managed to frequency rather than punctuality. For the trains where data is available, the percentages departing within a certain number of minutes are:

Under 2 Minutes 17.4%

2-5 minutes 25.6%

5-10 minutes 30.4%

Over 10 minutes 26.5%

There are 33 days out of 263 where we have no data. This may be due to the cancellation of this train.

2) on average how many minutes late does this service depart

The average departure of the 230 recorded trains is 7:02 minutes later than 07:39 a.m.

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

If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.

Yours sincerely
