A fault with the signalling system at Grays means that fewer trains are able to operate towards London.
Trains may be delayed by up to 10 minutes or revised.
Passengers who require Dagenham Dock, Rainham & Purfleet are advised to travel to Barking Station, and board a country-bound service from there.
You may use your ticket on London Buses on the following routes:
103 between Rainham & Dagenham East (Tube station)
287 between Dagenham Dock & Rainham via Dagenham Dock
EL2 between Dagenham Dock & Barking
