Rock Ferry station first opened on 31 October 1862 replacing Rock Lane on the Chester and Birkenhead Railway. In 1891 it became an interchange as the terminus of the largely underground urban Mersey Railway line from Liverpool via the Mersey Railway Tunnel, when the line extended south from its previous terminus at Green Lane station. The Mersey Railway was converted to electric train services from steam in 1903. The station was also a through stop and interchange on the Chester to Birkenhead Woodside terminal station non-electric line giving connections to the Mersey Railway. Until 1967 Rock Ferry was the first stop out of Birkenhead Woodside on the former GWR main line from Birkenhead Woodside to London Paddington station. All long-distance services called at Rock Ferry to give interchange connections with the Mersey railway for Liverpool bound passengers.

From 1967 with the closure of Birkenhead Woodside station the Rock Ferry station became a 100% terminus and interchange station for electric services from the north from Liverpool's city centre and diesel trains services from the south from Chester and Helsby. The electric services to Liverpool were integrated into the Merseyrail urban network in the 1970s becoming the Wirral Line.

In 1985 the Merseyrail Wirral Line was extended to Hooton, Chester and Ellesmere Port from Rock Ferry with the station becoming fully integrated into the Merseyrail urban network. This integration transformed Rock Ferry into a through-station. The first Merseyrail section extension was to Hooton in 1985, then to Chester in 1993 and finally Ellesmere Port in 1994. The section of line from Ellesmere Port to Helsby was not electrified with the line having only a 'Parliamentary' service. Recent refurbishment work to the station has included the restoration of a building on the island platform and installation of a fully accessible toilet and waiting room. The booking hall and entrance have also benefited from improved security and lighting.^[when?] The old Merseyrail terminating tracks are now used as stabling sidings with the platforms only having one or two passenger services to Liverpool starting in the early in the morning. Platform 3 is only used once a day from Monday to Saturday before 0600 and Platform 4 is used twice before 0800 on Sundays.

The station is staffed, during all opening hours, and has platform CCTV.^[1] There is a payphone, a vending machine and a booking office. Each of the two remaining former GWR/LMS Joint platforms now in use has sheltered seating and live departure and arrival screens, the Liverpool-bound platform retaining its canopy; the two bay platforms which were formerly used by the Mersey Railway are now used primarily for carriage storing; the two further former GWR/LMS Joint platforms are abandoned and out of use. The station has a free car park, with 25 spaces; it also has secure cycle storage for 24 cycles.^[2] Access to the station is by ramp. The only access to the Chester/Ellesmere Port bound platform for passengers with wheelchairs or prams is via a stepped ramp.^[3]

Trains operate every 15 minutes between Chester and Liverpool on weekdays and Saturdays until late evening when the service becomes half-hourly, as it is on Sundays. Additionally there is a half-hourly service between Liverpool and Ellesmere Port all day, every day.^[4] Northbound trains operate via Hamilton Square station in Birkenhead and the Mersey Railway Tunnel to Liverpool. Southbound trains all proceed as far as Hooton, where the lines to Chester and Ellesmere Port divide. These services are all provided by Merseyrail's fleet of Class 507 and Class 777 EMUs.
