We have just received this from C2C trains.
We do not expect trains to resume until at least 12.00 and our advice remains not to travel. We currently have power failures between Fenchurch Street and West Ham, and between Purfleet and Tilbury.
There has also been debris blocking the track at Thorpe Bay and Upminster. We are working with Network Rail to tackle these issues, and we will resume train services as soon as we can.
Disruption on C2C between Fenchurch Street and Pitsea due to overhead wire problems between Purfleet and Grays. Buses replace trains in both directions between Barking and Grays via Rainham. Trains are diverted via Upminster. Disruption is expected until approximately 2pm.
