The Northern line is one of two commuter rail routes operated by Merseyrail and centred on Merseyside, England, the other being the Wirral line. The cross-city route runs from in south Liverpool then (by way of an underground section through Liverpool's city centre) branches in the north to terminate at, (both Merseyside) and (Lancashire).
Passenger interchange to the Wirral line is available at Moorfields and Liverpool Central, and to the separately-owned City Line at Hunts Cross and Liverpool South Parkway. Liverpool South Parkway also allows interchange with regional and long-distance services, while connections to services operated by Northern Trains are possible at Headbolt Lane, Ormskirk and Southport.
The line runs from Hunts Cross in the south of Liverpool towards Liverpool Central. Brunswick station between and Liverpool Central was added in 1998 to provide a connection to the Brunswick Business Park. In the tunnel just south of Liverpool Central, the line drops into a 1970s tunnel to a lower level into the underground Mersey Railway Liverpool Central (Low Level) station. North of Central the line uses the Mersey Railway tunnel for about half of the route to Moorfields, an underground station built in the 1970s to replace the surface-level Liverpool Exchange. North of Moorfields, the route emerges from the tunnel to join the Lancashire and Yorkshire Railway lines from the former Exchange station.
After Sandhills, the former Liverpool, Crosby and Southport Railway branches off towards Southport, while the other routes continue to Kirkdale on what was a joint section of track between Liverpool, Ormskirk and Preston Railway and the Liverpool and Bury Railway. After Kirkdale, the Ormskirk and Headbolt Lane lines diverge.
Generally, trains from Hunts Cross continue to Southport, while trains to Ormskirk and Headbolt Lane start at Liverpool Central. Daytime trains operate every 15minutes on each of the three routes Monday to Saturday daytime and every 30minutes evenings and Sundays. Until 2017, summer Sunday frequencies on the Southport route were increased to every 15minutes. There are no peak hour frequency increases but trains on the Southport and Ormskirk routes are increased to six carriages, as are weekend services during the summer on the Southport route.[5]
Special timetables are implemented for major events such as the Grand National meeting at Aintree and golf tournaments at Birkdale. These involve changing services on all branches and the closure of stations in anticipation of overcrowding risks.[6]
Passengers from the year beginning April 2002 to the year beginning April 2022.
There are a total of 11 trains per hour (tph) running on the central section between Sandhills and Liverpool Central. The service pattern is:[7] (Not all stops listed; trains call at every station on their route.)

The Northern Line was introduced in 1977.
In 2006, Garston station was replaced by Liverpool South Parkway station.
The line is electrified using, identical to the third rail system present in southern England.
Interchange with the Wirral line is available at and . As the Northern line does not pass through, passengers from other rail networks must use the Wirral line as a connection. As there is only a direct escalator down to the Wirral line towards Birkenhead at Liverpool Central and given the short distance between Central and Lime Street most passengers prefer to walk rather than use the several escalators necessary to travel between the two stations.
Liverpool city centre stations have lifts for wheelchairs buggies and heavy luggage but they are small.
Interchange with other National Rail services can be made at Southport, Ormskirk, Headbolt Lane, Liverpool South Parkway and Hunts Cross.
Liverpool South Parkway opened on 11 June 2006, replacing Garston and providing connections to the City Line formerly available at .
Plans to re-open St James station have been proposed. Merseytravel agreed to work with Liverpool Vision in March 2014 to investigate the cost of re-opening the station and its projected usage.[9] Merseytravel listed the re-opening of St James station as a 'top rail project' on a Rail Development and Delivery Committee report in 2016. The plans were confirmed with the station to be named Liverpool Baltic, construction is planned to begin in 2025.[10] [11]
As part of Lancashire County Council's plans to build a new railway station in Skelmersdale, they proposed an extension to the Northern Line that would change the terminus of the Kirkby branch of the line from Kirkby (now Headbolt Lane) to Skelmersdale. The proposals could see Merseyrail services also passing through Rainford railway station. By September 2017, Merseytravel and Lancashire County Council had committed £5million of funding to the scheme. Merseytravel believe the scheme could cost around £300million to develop and could be ready in a decade.[12]
Liverpool City Region Combined Authority, Long Term Rail Strategy document of October 2017, page 37, states a review in 2020 to introduce new Merseyrail battery trains will be undertaken, in view to put Preston onto the Merseyrail network by extending the Merseyrail Northern Line from Ormskirk to Preston. The aim is to have Preston one of the terminals of the Northern Line. The document states, "The potential use of battery powered Merseyrail units may improve the business case".[13]
