The Northern line is one of two railway lines operated by Merseyrail, a commuter rail network which serves Merseyside and adjacent areas of Lancashire and Cheshire, in North West England. The line has its southern terminus at Hunts Cross in south Liverpool, from which it runs in a generally northerly direction through Liverpool city centre before splitting into three branches which terminate at Southport, Ormskirk and Headbolt Lane. It serves a total of 39 stations.
The line has interchanges with the Wirral line, Merseyrail's other line, at Moorfields and Liverpool Central, which are subterranean stations. Hunts Cross and Liverpool South Parkway allow interchange with City line services, and Liverpool South Parkway also allows interchange with regional and long-distance services. Northern Trains services can be connected to at Headbolt Lane, Ormskirk and Southport.

The line from Walton Junction to Liverpool Exchange was constructed by the Liverpool and Bury Railway (L&BR), opening in 1948 between Walton Junction and Great Howard Street, although the line would open under the Lancashire and Yorkshire Railway (L&YR) after a merger occurred a year prior in 1847. The line would extend to a station on Tithebarn Street in 1850, before finally reaching Liverpool Exchange in 1888. The lines towards Aintree and Ormskirk were built by the Liverpool, Ormskirk and Preston Railway, itself also taken over by the L&YR in 1847, with the lines opening two years later in 1849. The whole section between Southport and Sandhills was constructed by the Liverpool, Crosby and Southport Railway (LC&SR), opening from Southport to Waterloo in 1848, and then to Sandhills in 1850. The LC&SR would be taken over by the L&YR as late as 1855.: 1
The line is electrified using 750 V DC third rail, identical to the third rail system present in southern England. It was also amongst the first main lines to be electrified, done so by the Lancashire and Yorkshire Railway due to increased tram competition and the line being at operating capacity.: 2 Unlike today, this was originally done with a fourth rail system similar to that seen in London: 3 although, from 1906 onwards, the fourth rail would be excluded, with it slowly removed from prior sections.: 4
Early electrification was completed in several stages:
Electrification was cut back to Southport in the north in 1964 as part of the Southport-Preston line closure under the Beeching Cuts,: 4 stations closing which previously had electric services were St Lukes, Hesketh Park, Churchtown and Crossens. Electric services also ceased running to Meols Cop, although the conductor rail remained until 1970 to serve the large depot near the station, which continues to serve trains on the Southport to Wigan/Manchester line today.
It was also fully intended for the whole main line between Southport and Liverpool Exchange to also be closed under the Beeching Cuts, although the North Mersey Branch to Ormskirk would remain unscathed. This would not go ahead, with various forms of action undertaken to lessen maintenance on the line, such as removing platform canopies, and even in some cases platform buildings.: 20 After a study was undertaken in 1969, referred to as the Merseyside Area Land Use & Transportation Study, by the then Merseyside Passenger Transport Authority, the Northern Line would be introduced in 1977 alongside the new Link Line under the Mersey Railways Extensions Act of 1968;: 4 this would see the previously threatened main line to Southport and the branch to Ormskirk secured and brought under this new line.: 22

Electrification done as part of the new Link Line are as follows:
Later additions and extensions to the line, after the Link line was opened in 1977, were:

Services from Hunts Cross generally continue to Southport, while trains to Ormskirk and Headbolt Lane start at Liverpool Central. Daytime trains operate every 15 minutes on each of the three routes, but every 30 minutes evenings and Sundays.
Special timetables are implemented for major events, such as the Grand National meeting at Aintree Racecourse and tournaments at Royal Birkdale Golf Club. These involve changing services on all branches and the closure of stations in anticipation of overcrowding risks.
There are a total of 12 trains per hour (tph) running on the central section between Sandhills and Liverpool Central. The service pattern is shown below.

Plans to reopen St James station have been proposed. Merseytravel agreed to work with Liverpool Vision in March 2014 to investigate the cost of reopening the station and its projected usage. Merseytravel listed the reopening 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.
As part of Lancashire County Council's plans to build a new station at Skelmersdale, it proposed an extension to the Northern line that would change the terminus of the Kirkby branch of the line from Headbolt Lane to Skelmersdale. The proposals could see Merseyrail services also passing through Rainford. By September 2017, Merseytravel and Lancashire County Council had committed £5 million of funding to the scheme. Merseytravel believe the scheme could cost around £300 million to develop and could be ready in a decade.
The combined authority's Long Term Rail Strategy states that a review in 2020 to introduce new Merseyrail battery trains will be undertaken, in view to add Preston in to the network by extending the Northern line from Ormskirk. It adds that "the potential use of battery-powered Merseyrail units may improve the business case."
