Travellers in Essex are experiencing disruptions as some train lines have been blocked.
Greater Anglia reported faulty overhead electric wires between Manor Park and Romford caused blockages on some lines.
The damage in the Ilford area has train services to Southend Victoria, Witham, Colchester, Ipswich and Norwich delayed, altered or cancelled.
According to the train provider, the Elizabeth Line will pass GA ticket holders between Liverpool Street and Shenfield and vice versa.
C2C will also pass ticket holders between Fenchurch Street and Southend, while London Underground will pass Greater Anglia ticket holders.
The disruptions are expected to continue until further notice.
