More power supply problems have hit rail routes into London this morning, leaving passengers stuck on trains.

The disruption affecting trains into the capital from Essex meant no services were able to run between Tilbury Town/Upminster and Fenchurch Street.

Some trains came to a standstill, with problems for passengers compounded later by a trespasser on the tracks.

Passenger Sarah Calkin tweeted: "O my God. I'd be better off walking to London."

Eventually, a limited amount of power was restored and the stationary trains were able to start moving.

The problem affected passengers with the c2c train company.

Some travellers switched to using Abellio Greater Anglia trains which also became packed.

Four weeks ago a similar power supply problem near Clapham Junction resulted in some commuters being stuck on trains for several hours.

Elsewhere this morning, there were delays of up to an hour on Chiltern trains in and out of Marylebone after a signalling problem.
