FOI request detail

Percentage of Journeys Successfully Completed

Request ID: FOI-0220-1819
Date published: 25 May 2018

You asked

Introduction: As everyone on the Shenfield - Liverpool Street line understands, the service is spotty and defective. Train faults, signaling faults, delays and trains deciding not to stop at stations. Request: I'd therefore like detailed statistics day by day, for defective journeys (late, even by a few minutes, cancelled, non-stopping at scheduled stops etc. etc.) and completed journeys for the period June 2015 to the present. This should result in a CSV file (from one of the systems like Darwin, for example) of about 100K rows. One SQL query, if that's how the data is stored.

We answered

TfL Ref: 0220-1819

Thank you for your request received by Transport for London (TfL) on 26 April 2018 asking for information about TfL Rail journeys.

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.

The Class 315’s (our older Fleet), are currently being taken through a modification programme to enhance their reliability. A number of components and systems are being replaced, along with some new equipment to aid the operation of these units. All Class 345’s are going through an upgrade too, both hardware and software related to improve overall reliability. Recent initiatives have included the replacement system components, which have led to a number of cancellations in recent weeks.

We are carrying out further training with our staff on customer services in order to reduce delays particularly in the AM & PM Peak periods. We are continuing to work closely with Network Rail (who own and maintain the infrastructure), to ensure asset reliability is upheld. A key area of focus is around the signalling equipment and vegetation management, the latter of which should prove beneficial in the Autumn period.

Please see attached the data you have requested. (Column D represents how early/late a train arrives at its destination. A negative number represents early arrivals and a positive number represents late arrivals. 0 indicates that the train arrives at its destination on time. For example, 2 indicates that the train arrives at its destination 2 minutes late. In column E, 0 represents that the train has stopped at all its planned stops and 1 indicates that the train has been cancelled for one or more of its planned stop). 

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
