Please could you give the % of London Overground trains, on the ELL branch, which departed Canonbury for Highbury and Islington at the actual timetabled time ( not 3 or 5 minutes after this) for the period November 2017 until the present time (July 2018).

Our ref: FOI-1048-1819/GH

Thank you for your request received by Transport for London (TfL) on 13 July 2018 asking for information about London Overground performance.

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 some of the information you require.

Unfortunately we are only able to provide right time departure in both directions (not just to Highbury and Islington as requested).

During the period requested the percentage of right time departures from Canonbury was 59.46%, (44,823 of 75,388 trains).

Please also see the table below which shows the T-3 figure for the same period, and demonstrates that c90% of trains arrive (and therefore depart) within 3 minutes of their scheduled time.

Period	T-3
P5	89.78
P4	86.28
P3	93.8
P2	92.08
P1	89.6
P13	90.08
P12	84.99
P11	86.17
P10	86.91
P9	82.41
P8	79.96

If this is not the information you are looking for, 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
