Thousands of frustrated commuters in Hackney are having their journeys
disrupted every single day as Overground trains bound for Highbury and
Islington terminate early without warning.

Operator Transport for London (TfL) is blaming under-fire Southern Rail
for the problems, which have spiked in the last month with 392 of the
11,806 trains affected - or 3.5 per cent.

Terminating Grayling would be a good start.
