I wish to discover the reliability of the first Jubilee line train of the day from Stratford, train number 361 departing at 0515. I would like to know the reliability of this train based upon it's arrival or departure time at Green Park. Should Green Park not be available as a timing point, an alternative point beyond Green Park is sufficient. Please provide the relevant data you hold for this service for a six-month period (shortened if Cost Limits would be exceeded) starting January 1st 2019. Ideally the information would be provided as a number of trains running on-time, within three minutes, within six minutes and over six minutes late; however I am willing to accept data in an alternative format if necessary (such as times for each day individually).

TfL Ref: 2245-1920

Thank you for your request received by Transport for London (TfL) on 25 October 2019 asking for information about the Jubilee 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.

Please see attached. Please note the caveats below when looking at the data.

The reliability of the first train from Stratford to Green Park is good with the train was only cancelled three times during the time period covered by your request and only over 5 minutes late on 3 occasions.

Caveats:-

• Starting point West Ham used as Stratford is the termini station and the data does not return results therefore next stop westbound used

   

• Data is from 1^st January 2019 to 30^th June 2019

   

• Data excludes days that are:- weekends, bank holidays and days where the train has missed it’s trip due to cancellation

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
