After World War II and following nationalisation, it fell under the auspices of British Railways (Eastern Region).Initially, the line was only electrified as far as Colchester, as part of British Railways' experiments with 25 kV AC electrification, rather than the previously preferred 1500 V DC system.[5] Clacton Servicing Depot lies just beyond the platform ends, with some stabling sidings alongside the station itself.[6] The typical service is one train per hour to London Liverpool Street, calling at Thorpe-le-Soken, Wivenhoe, Colchester, Witham, Chelmsford, Ingatestone, Shenfield and Stratford.The Class 321 electric multiple units that used to form the services at this station were withdrawn at the end of April 2023.
