Clacton-on-Sea railway station serves the town of Clacton-on-Sea in Essex, England. It is located to the north of Clacton town centre, within walking distance of the sea and pier.
The station is the terminus of the Clacton branch which diverges from the Great Eastern Main Line at Colchester. There is a frequent train service between Clacton and London Liverpool Street.
The station itself has a sizeable concourse sheltered by a glazed roof. There is a traction depot just outside the station, with some stabling sidings alongside the station itself.
Its name was changed from Clacton to Clacton-on-Sea railway station in May 2007.
Although services are operated by National Express East Anglia, the sign on top of the ticket office and main entrance still reads First Great Eastern; a reminder of the franchise holder prior to 2004.
