Moorfields railway station is an underground railway station in the city centre of Liverpool, England. The station is situated on both the Northern and Wirral Lines of the Merseyrail network. It is the third-busiest station on the Merseyrail network, and the largest underground station. It is also the only station on the network having services to all other Merseyrail stations. History The station was built in the 1970s, as a replacement for Liverpool Exchange railway station, opening on 2 May 1977. The station was opened by British Rail and is accessed via entrances at Moorfields and on the corner of Old Hall Street and Tithebarn Street. The Old Hall Street entrance is open from only 5:30 am until 7 pm on weekdays. Services from the north had previously terminated at nearby Liverpool Exchange terminus station. The newly created north–south crossrail Northern Line runs through Moorfields. Liverpool Exchange was closed and the line extended underground to the new Moorfields station. The line from the north continued through a new tunnel to Liverpool Central, continuing south to terminate at Garston. The line was later extended to Hunts Cross and opened in 1983. At the same time, another new tunnel was built, carrying the Wirral Line in a loop from James Street via Moorfields, Lime Street, and Liverpool Central before returning to James Street; the Wirral Line platform opened on 30 October 1977. There are three platforms (two for the Northern Line and one for the Wirral Line) in two levels of tunnel. The Wirral Line platform is at a much deeper level to pass under the Queensway road tunnel. Passengers must, curiously for an underground station, go up an escalator from the Moorfields entrance to reach the ticket office – the station was originally intended to connect with a pedestrian walkway system, designed to separate pedestrians from traffic. Only a small section of the system was constructed in the 1970s and the scheme eventually fell by the wayside. From the ticket office, another escalator leads down to the main pedestrian tunnel which links the Northern and Wirral Line platforms and the Old Hall Street entrance. The usage of the station Monday to Friday is much greater than the statistics show, since they credit "Liverpool" passengers to Lime Street station, and do not include day or season ticket holders. The station is however significantly quieter at weekends, since it is primarily used by
