Rush-hour trains made up of four carriages instead of eight

Services from Chingford to Liverpool Street are experiencing delays of up to 30 minutes, according to London Overground's Twitter account.

At least four trains this morning are being made up of four carriages instead of eight.

The 8.05am train is now due at 8.32am, the 8:44am has been delayed until 9:13am, and the 9:18am is expecting to leave Chingford at 9.44am.

TfL's director of rail Jonathon Fox told the Guardian earlier this month that the poor service was down to six out of 31 trains being faulty.

He explained that TfL had started a five-week programme over the summer holidays to fix the remaining faulty doors on the trains inherited from Greater Anglia.

4 Car - 8:05 & 09:18 Liverpool Street to Chingford due 08:32 & 9:44 will be formed of 4 coaches instead of 8.
