History of Merseyrail

The history of Merseyrail dates back to the 19th century, with the original formation of the Mersey Railway, however, Merseyrail dates back to the 20th century, namely being set up by British Rail in 1969, it did not become a single network until 1977.

When Merseyrail originally opened, there was 50 stations on the network, that has since expanded to almost 70.

The first Mersey Railways (19th Century - 1930s)
The present Merseyrail network was merged from the lines of five former rail systems, those being


 * The Mersey Railway (Liverpool Central to Rock Ferry, Birkenhead Park)
 * The Cheshire Lines Committee railway (Liverpool Central to Hunts Cross section)
 * The Lancashire and Yorkshire Railway (Liverpool Exchange to Kirkby, Ormskirk and Southport sections)
 * The Wirral Railway (Birkenhead Park to New Brighton and West Kirby)
 * The Birkenhead Joint Railway (Rock Ferry to Hooton and Chester section and the Ellesmere Port branch).

The centre of all these lines, Mersey Railway, opened and ran originally from Liverpool James Street to Green Lane, running through the 1886 Mersey Railway Tunnel, one of the worlds first underwater railway tunnels. In 1880's and 90's the network was expanded to include Liverpool Central (1890), Birkenhead Park railway station (1888), to connect with the Wirral Railway. This lead to the expansion of the network to Rock Ferry railway station and the connection to the Chester Line in 1891.

In 1903, the Mersey Railway was electrified, becoming the worlds first full electrification of a steam railway. This was followed by the electrification of the Lancashire and Yorkshire Railway line from the Liverpool Exchange railway station to Southport railway station, which took place in 1906. In 1937, the further electrification of the Wirral Railway Lines to New Brighton railway station and West Kirby railway station and allowed for through running into Liverpool via the Mersey Railway Tunnel.

Creation of Merseyrail (1963 - 1977)
The Beeching axe in the early 1960s triggered widespread railway closures, targeting key routes like Liverpool - Southport, Liverpool - Wigan Wallgate, and the stations of Liverpool Exchange, Liverpool Central (High Level) and Birkenhead's Woodside station.

In response, Liverpool City Council proposed a contrasting strategy, advocating for the preservation of suburban services integrated into a new regional electrified rapid-transit network. This initiative aimed to link all lines via innovative tunnels under Liverpool and Birkenhead, facilitating seamless transportation across Merseyside. The Merseyside Area Land Use and Transportation Study (MALTS) supported this vision, leading to the establishment of Merseyrail upon Liverpool City Council's proposal being adopted. Merseyrail was conceived to streamline urban travel, ensuring convenient access to Liverpool Lime Street for long-haul routes by diverting local services underground in Liverpool's centre. Consequently, the government opposed closure of the Liverpool-Southport and Liverpool-Wigan Wallgate lines but approved the shutdown of multiple stations, consolidating Liverpool's rail operations primarily at Lime Street while curtailing the electrified section between Southport and Crossens in 1964. Riverside Terminal Station at the Pier Head closed in 1971 due to declining transatlantic liner trade.

The formation of the Merseyside Passenger Transport Authority (later Merseytravel) in 1969 was tasked with overseeing local rail lines destined for inclusion in the newly envisioned Merseyrail network. Initially, Liverpool operated separate entities for electric and diesel-hauled lines. Lines for the new Merseyrail system were categorized into the 'Northern Line' (from Exchange and Central High Level), 'Wirral Line' (from Central Low Level), and 'City Line' (from Lime Street station). The Strategic Plan for the North West (SPNW) in 1973 envisioned comprehensive electrification and integration of lines into Merseyrail by 1991, including the Outer Loop, Edge Hill Spur, and connections to St. Helens, Wigan, and Warrington.

Four construction projects were outlined to create the rapid-transit network:


 * 1) Loop Line: Extending Wirral lines in a loop around Liverpool's city centre.
 * 2) Link Line: A tunnel linking northern and southern lines under Liverpool city centre to form the Northern Line.
 * 3) Edge Hill Spur: Reusing the recently closed 1830 Wapping Tunnel from Edge Hill to Central Station for eastern lines' access to the underground city centre.
 * 4) Outer Rail Loop: A comprehensive suburban loop around Liverpool, split into northern and southern segments, with plans for a major six-platform underground station at Broad Green where the two loops and the St.Helens/Wigan line met.

While the Loop Line and Link Line were completed, establishing the fully electrified Northern and Wirral Lines, the Edge Hill Spur and Outer Rail Loop projects were shelved later, leaving the City Line isolated. This hindered its integration into Merseyrail, maintaining local services into Lime Street and using platforms needed for long-haul routes. Efforts to complete these projects faced political hurdles, and it wasn't until the 2015 electrification of Lime Street to Manchester and Wigan lines that progress was made, although the line to Warrington retained diesel traction. Merseytravel initially sponsored Merseyrail branding in stations and liveries on local services, with the latter ending following British Rail's privatization, allowing operators to adopt individual corporate liveries.

The Loop and Link Project
The major engineering works required to create the Northern and Wirral lines became known as the 'Loop' and 'Link' Project, consisting of two tunnels. The 'Loop' was the Wirral Line tunnel and the 'Link' the Northern Line tunnel, both under Liverpool's city centre. The main works were undertaken between 1972 and 1977. A further project, known as the Edge Hill Spur, would have integrated the City Lines into the city centre underground network. This would have meshed the eastern section of the city into the core underground city centre section of the electric network, releasing platforms at mainline Lime Street station for mid to long haul routes. The Edge Hill Spur was not completed due to budget cuts.

The Loop Line (Wirral Line)
The Loop Line is a single-track loop tunnel under Liverpool's city centre serving the Wirral Line branches. It was built to allow both greater capacity and a wider choice of destinations for Wirral Line users, which included the business and shopping districts of Liverpool city centre and the mainline Lime Street station. The loop extension offered direct mainline station access to Wirral residents after the decommissioning of the mainline Woodside terminal station in Birkenhead.

Trains from Wirral arriving via the original Mersey Railway tunnel enter the loop beneath Mann Island in Liverpool continuing in a clockwise direction through James Street, Moorfields, Lime Street and Central, returning to the Wirral via James Street station. The loop tunnel gave interchanges for passengers of the Wirral Line to the Northern Line at Moorfields and Central stations.

A burrowing junction was constructed at Birkenhead Hamilton Square station, to increase traffic capacity on the Wirral Line by eliminating the flat junction to the west of the station. This included a new station tunnel at Hamilton Square to serve the lines to New Brighton and West Kirby.

The Link Line (Northern Line)
The Link Tunnel was designed to connect the north and south urban lines of Liverpool, creating a continuous north-south Northern Line. This line also formed the western section of a proposed double-track electrified suburban orbital line, the 'Outer Rail Loop', though budget cuts prevented eastern section construction.

The Link Tunnel is a double-track tunnel connecting two lines: one running south from the city centre to Hunts Cross, and another running north to Southport, with branches to Ormskirk and Kirkby. This line provides direct access from Liverpool's north and south to the city centre's shopping and business districts via two underground stations, Liverpool Central and Moorfields, both of which interchange with the Wirral Line’s Loop Line.

Liverpool Central's Northern Line underground station was originally the Mersey Railway terminus at Central Low Level. A section of the original 1880s tunnel between James Street and Central stations was repurposed for the Link Tunnel. The remaining section, between Paradise Street Junction and Derby Square Junction, is used as a rolling stock interchange between the Northern and Wirral Lines and as a reversing siding for Wirral Line trains terminating at James Street when the Loop Tunnel is inactive. This interchange tunnel section is not used for passenger traffic.

A new track layout south of Liverpool Central eased connections between the former Mersey and Cheshire Lines railways. This allowed extending the Northern Line to Garston and later Hunts Cross. To achieve this, a tunnel was excavated, connecting the previously separate high and low-level tracks. Additionally, a new single-track tunnel was built for reversing trains towards Garston since the existing tunnel couldn't fit three tracks. Furthermore, engineers also built short tunnels to prepare for a potential future project (Edge Hill Spur) that would create a new connection without disrupting current services. This future junction would function similarly to the existing burrowing junction at Hamilton Square, allowing for increased capacity.

Expanding the network (1977 – present)
The Loop and Link project was followed by a programme of expansion, electrification and new stations, which built on the greater integration and capacity provided by the new infrastructure.

Walton to Kirkby
On 30 April 1977, Liverpool Exchange terminus station was closed as a part of the Link tunnel project to create Merseyrail’s electrified north-south cross-rail Northern Line. This new tunnel under Liverpool’s city centre enabled the creation of a continuous rail line, with nearby Moorfields underground station replacing Liverpool Exchange. Diesel trains from Wigan Wallgate station, unable to operate in the underground stations for safety reasons, were temporarily terminated at Sandhills, the last surface station before the tunnel.

In 1978, the electrification of the line from Walton to Kirkby extended Merseyrail, creating a Northern Line branch terminus at Kirkby. This cut the northern Liverpool to Manchester route route into two sections with different modes of traction, 750 V DC third rail electric on the Merseyrail network and diesel on the Northern Rail network. Consequently, the diesel service to Wigan was cut back to Kirkby, with Merseyrail and Northern Rail trains using opposite ends of the same platform for ease of interchange.

Liverpool Central to Garston and Hunts Cross
Also in 1978, the Northern Line was extended south from Liverpool Central under the Merseyrail brand, terminating at Garston instead of the former Gateacre terminus, which had been abandoned in 1972. The new line linked the tunnel into Central High Level with the lower-level tunnel entering Central Low Level. This connection was originally envisaged when the Mersey Railway was extended to Central from James Street in the 1890s, ensuring the two tunnels were on the same alignment. A short extension to Hunts Cross in 1983 enabled passenger interchange between Northern Line services, the Merseyrail City Line, and mainline services from Lime Street. The reopened line needed to cross the southern Manchester line via Warrington on the flat, which affected capacity.

Rock Ferry to Hooton, Chester and Ellesmere Port
Rock Ferry railway station had been a terminus for Wirral Line services since the Mersey Railway was extended there from Green Lane in 1891. Passengers for the lines to Chester and Helsby would change trains at this station from the electric service on to mainline services operated by steam and diesel. Rock Ferry became one of the terminals for the Merseyrail Wirral Line. In 1985 the line from Rock Ferry to Hooton was electrified and incorporated in the Wirral Line of Merseyrail, making Hooton a new terminus.

Hooton is a junction station where the line to Helsby via Ellesmere Port branches off the main Chester line. The line from Hooton to Chester was electrified in 1993, making Chester a terminus station of the Wirral Line. The line from Hooton to Ellesmere Port was electrified in 1994 and incorporated into the Wirral Line, making Ellesmere Port a terminus and interchange station.

Kirkby to Headbolt Lane
In 2023, Headbolt Lane replaced Kirkby as the terminus of the Kirkby/Headbolt Lane Line. This expansion to the network became the UK's first BEMU fleet in use for passenger services, as there is no electrification past Kirkby, relying completely on batteries.

New stations
A programme of new stations expanded the Merseyrail network, including:
 * (1983), (1985),  (1988),  (1995),  (1998),  (1998),  (2017),  (2023)

opened in 2006 on the site of Holly Park football ground of South Liverpool F.C. in South Liverpool. It is an interchange station between the Merseyrail Northern Line from Liverpool Central to Hunts Cross and the City Line from Liverpool Lime Street to Runcorn and Warrington Central and also mainline services. The station also includes a bus terminal and large car park, with frequent bus services to Liverpool John Lennon Airport. It was formed from an amalgamation of the four-track Allerton station and the relocation of the Merseyrail Garston Station, which closed upon the opening of the new facility, marking the first station closure on the Merseyrail network since Liverpool Exchange in 1977.

Expanding the network through electrification
Many proposals to electrify lines adding them to the existing Merseyrail network have been proposed over past decades. However, in 2017 the Department for Transport announced that electrification of lines in Britain will only be where necessary with many planned projects cancelled. Bi-modal trains with combinations of battery electric, hydrogen fuel cell and diesel engines are the preferred options.

Tram-trains
In August 2009, it was reported that a new tram-train link to Liverpool John Lennon Airport and a link to Kings Dock from the east of the city had been proposed.
 * Liverpool John Lennon Airport: the existing Northern Line and the City Line from Liverpool Lime Street to Liverpool South Parkway are being assessed. From South Parkway the tram-trains would transfer to a new tramway. Merseytravel commissioned a feasibility study into increasing rail links with the airport in 1995 but no further work has been undertaken.
 * Kings Dock to Edge Hill: a link from Edge Hill in the east of the city to the Arena at Kings Dock in the city centre was also being considered.

Future development
There have been various suggestions for ways to enlarge the Merseyrail network. In August 2014, Merseytravel gave details of a 30-year plan for the network to be presented to the leaders of the city region.

Some proposals would extend beyond the current Liverpool City Region area, while others would use former existing lines or track beds inside the area. In November 2016 the details of the next phase of the Merseyrail fleet were announced: if trains capable of use beyond the third-rail DC network are selected as replacements, various expansions can be achieved without electrification of the entire new route. The newly acquired Class 777 trains are capable of operating on non-electrified track, drawing this aspiration closer.

In July 2021, the metro-mayor of the Liverpool City Region announced that bi-modal battery electric Class 777 trains will operate on Merseyrail, extending the network. He stated "This capability means they could eventually provide a direct service from as far as Preston and Wrexham."

The Rail Strategy published in 2020 states:


 * Other options that could be further developed by funders or stakeholders (to meet connectivity based conditional outputs) following this study could be:
 * Extending the Merseyrail network to Shotton (and possibly on to Wrexham);
 * Extending the Merseyrail network to Skelmersdale (and possibly on to Wigan Wallgate); and
 * Extending the Merseyrail network to Burscough Junction (and possibly on to Preston).

Liverpool Baltic station
The former St James railway station, now disused, is located on the corner of St.James' Place and Parliament Street in the Baltic Triangle district, having been closed in 1917. The station is in a deep cutting on the operational Northern Line tunnel section between Liverpool Central Station and Brunswick Station.

Liverpool City Region Combined Authority announced in August 2019 that it was planning to use part of a £172million funding package to reopen St James Station in Liverpool City Centre.

In 2020, a series of investments and land purchases advanced the case for a station at the site of St James in the Baltic Triangle. Part of the Spatial Regeneration Framework for the area includes a new Baltic Triangle railway station. In April 2022, following a public vote, the new station was official confirmed as Liverpool Baltic station. In a marketing video released by Merseyrail in 2023, following the 20th anniversary of the company, they confirmed Baltic Station was in the design phase.

Vauxhall station
In its 30-year plan of 2014, Merseytravel mentions the possibility of a new station between Moorfields and Sandhills in the Vauxhall area on the Northern Line. A station at this location would serve the under construction Everton F.C. stadium at Bramley-Moore Dock, which is near to the Northern Line.

Use of battery-powered trains
The Liverpool City Region Combined Authority Long Term Rail Strategy document of October 2017 stated that trials of new Merseyrail battery trains would be undertaken in 2020. The aim was to extend the electric network onto unelectrified track. A number of lines were targeted for electric third rail/battery train trials, for network extension. Merseyrail Class 777 electric trains have the capability to operate on unelectrified track, which otherwise would not be considered for track electrification on cost grounds. The lines chosen for the trials are: The Liverpool City Region Combined Authority announced in July 2021 that the trial had been successful. The new units were able to travel up to 20miles on the fitted batteries. This opens up the possibilities of the trains being used to serve other destinations such as Skelmersdale, Wrexham, Warrington and Runcorn.
 * Ellesmere Port to Helsby: the Liverpool City Region Combined Authority Long Term Rail Strategy document of October 2017 stated on page 37 that a trial of new Merseyrail battery trains will be undertaken in view to incorporate the 5.2 mi stretch of track from Ellesmere Port to Helsby interchange station onto the Merseyrail network. A successful outcome may make Helsby one of the terminals of the Wirral Line replacing Ellesmere Port, with Stanlow and Thornton and Ince and Elton stations brought into the network.
 * Ormskirk to Preston: the Liverpool City Region Combined Authority Long Term Rail Strategy document of October 2017 also mentioned on page 37 the incorporation of Preston onto the Merseyrail network by extending the Merseyrail Northern Line over 15 mi from Ormskirk to Preston interchange station. The aim was to make Preston one of the terminals of the Northern Line, with Burscough Junction, Rufford and Croston stations brought onto the Merseyrail network. The document stated, "The potential use of battery powered Merseyrail units may improve the business case. This will be reviewed after the Merseyrail units have been tested for battery operation in 2020."

Possible network extension using battery trains
Merseytravel purchased Class 777 trains with battery electric technology after successful trials on unelectrified track sections, reducing the need for full track electrification. To meet the Liverpool City Region's Long Term Rail Strategy, Merseytravel aims to extend the network beyond current boundaries, targeting Skelmersdale, Wrexham, and Warrington. Many lines previously considered for electrification are now candidates for battery electric operation.

Headbolt Lane to Wigan
In 1977, the Liverpool to Kirkby section of the Liverpool-to-Bolton route was electrified and integrated into Merseyrail, with Kirkby becoming the Northern Line terminus. Passengers traveling to Bolton had to change at Kirkby from the Merseyrail electric network to the Northern Rail diesel network. The Kirkby to Headbolt Lane station section is now operated by Class 777 hybrid electric/battery trains, using battery power from Kirkby to Headbolt Lane.

Extending the Northern Line to Wigan Wallgate has been a long-term goal. Network Rail identified this extension as a route that would benefit from electrification and enable new patterns of passenger services to operate. The Electrification Task Force prioritized the Kirkby to Salford Crescent electrification in 2015. Hybrid battery trains make extending to Wigan feasible without costly electrification, using battery power from Headbolt Lane to Wigan.

Ormskirk to Preston
Electrification from Ormskirk to Preston, including reopening the Burscough Curves, would create a direct Liverpool-Preston route, a long-term Merseytravel goal. However, in 2008 Network Rail deemed the cost-benefit ratio insufficient, though the scheme continued to be mentioned. Despite this, third rail battery electric train trials in 2020 aimed to provide a Liverpool-Preston service.

Bidston to Wrexham
The Borderlands Line from Bidston south to Wrexham Central, operated by Transport for Wales, uses diesel trains on unelectrified track. Proposals for full electrification have been rejected, with current plans favouring battery-powered trains. In 2015, Network Rail proposed battery-powered trains to enhance connectivity with the Wirral Line, avoiding full electrification costs.

Former operator KeolisAmey Wales announced plans in 2018 to use refurbished Vivarail Class 230 metro trains with on-board batteries and regenerative braking, putting full electrification on hold. Welsh Economy Secretary Ken Skates and Liverpool City Region metro-mayor Steve Rotheram have both expressed interest in running direct Wrexham to Liverpool services, with Rotheram favouring using Merseyrail Class 777 battery-electric trains.

Hunts Cross to Warrington
The Strategic Plan for the North West (SPNW) envisaged in 1973 that the Liverpool to Warrington line would be electrified and integrated into the Merseyrail Northern Line by 1991, making Warrington Central a terminus. In March 2015, the Electrification Task force placed electrifying the line from Liverpool to Manchester via Warrington Central in the Tier 1 priority category. The Liverpool City Region's Long Term Rail Strategy has clear aspirations to extend the network to Warrington, using the introduction of the Class 777 trains as an enabler.

Southport to Wigan
Southport to Wigan has been identified by Network Rail as a route where electrification in conjunction with extension of electrification from Ormskirk to Preston and reinstatement of the Burscough Curves would enable new patterns of passenger service to operate. In March 2015, the Electrification Task force placed the electrifying of the line from Southport to Salford Crescent via Wigan in the Tier 1 priority category.

Ellesmere Port to Helsby
Helsby is an interchange station on the Chester to Warrington Bank Quay and Ellesmere Port to Helsby lines. Merging the line from Ellesmere Port to Helsby into Merseyrail would create a Liverpool to Helsby service, giving a smooth interchange from Merseyrail to all stations on the Chester to Warrington line. The Ellesmere Port to Helsby route is included in Merseytravel's rail strategy as a "long-term aspiration". Third rail battery electric train trials were undertaken in 2020 by Merseyrail on this section of track using the new Class 777 battery/electric trains. The results may indicate that the network can be expanded to Helsby without further electrification.

Other battery electric extensions
Liverpool City Region metro-mayor Steve Rotheram stated that the City Region is planning to extend the network "so it reaches communities right across our city region and beyond". The Liverpool City Region map displays desired extensions of Merseyrail including a Chester to Runcorn East line. This line would operate on a section of the Chester to Warrington Bank Quay line, incorporating the Helsby interchange station. The Integrated Rail Plan proposes a new station at the next station, Warrington Bank Quay low-level. The new station were planned to serve HS2 and Northern Powerhouse Rail expanding the interchange.

Burscough Curves
The Burscough Curves were short chords linking the Ormskirk to Preston Line with the Manchester to Southport Line. These curves allowed direct northbound travel from Ormskirk to Southport and southbound travel from Preston to Southport. Regular passenger services ceased in 1962, and the tracks were removed. Reinstating the Burscough Curves would enable direct Preston-Southport and Ormskirk-Southport services, offering an alternative Liverpool-Southport route via Ormskirk. Network Rail has recommended further development of a strategy for the Burscough Curves. In a parliamentary debate on 27 April 2011, the Burscough Curves were a focal point. The transport minister expressed interest in discussing their reinstatement with former Southport MP John Pugh. Merseytravel's Long Term Strategy puts the opening of the curves in Network Rail's CP7 period.

The new Class 777 Merseyrail trains have been tested for battery electric operation, with the prospect of using them on the Burscough Curves open to review. Introducing battery trains on the Merseyrail network might strengthen the case for reopening the Burscough Curves, allowing Northern Line trains to travel from Ormskirk to Southport, giving two routes from Liverpool to Southport. If realised Burscough Junction, Burscough Bridge, New Lane, Bescar Lane and Meols Cop stations may be incorporated into Merseyrail.

Edge Hill to Bootle
The Canada Dock Branch line, also known as the Bootle Branch line, is an unelectrified line running from Edge Hill Junction in the east of Liverpool in a curve to the container terminal to the north. Passenger trains were withdrawn in 1977, but it remains in constant use for freight to the Seaforth Container Terminal. Proposals have been made to electrify and reopen the line to passengers, potentially reopening stations like Spellow, Walton & Anfield, Breck Road, Tuebrook, Stanley, and Edge Lane.

Network Rail's March 2009 Route Utilisation Strategy for Merseyside found that the benefits of new infrastructure on the Canada Dock Branch did not justify the investment. However, the Department for Transport's July 2009 rail electrification document stated that the route to Liverpool Docks would be electrified via overhead wires. The document noted that electrifying this route would enable electric freight transport, creating an alternative access to Liverpool docks for electrically-powered trains. Additionally, it was expected to enhance electrified connectivity to the planned freight terminal at Parkside near Newton-le-Willows.

Initial phases of electrification scheduled until 2016 did not list the line. Local residents campaigned for increased rail transport of containers to ease road congestion and pollution, which could further boost rail traffic. The Liverpool City Region Combined Authority's October 2017 Long Term Rail Strategy document outlined a proposal to introduce passenger services on the Bootle Branch into Lime Street, noting on page 37: "An initial study is required to understand fully the freight requirements for the line and what the realistic potential for operating passenger services over the line is." It was announced in December 2019 that Liverpool City Council had commissioned a feasibility study to explore reopening line to passenger traffic.

North Mersey Branch
The North Mersey Branch from Bootle to Aintree is currently used exclusively by engineering trains accessing Merseyrail tracks. Merseytravel aims to reopen and electrify this line in the long term. According to the Merseyside Route Utilisation Strategy (RUS), reopening the line is not currently recommended, although future development and regeneration could increase demand for these services. The RUS noted that any implementation must ensure that freight needs, both current and future, are met. Additionally, there may be long-term potential to use other infrastructure, such as the disused Wapping and Waterloo tunnels, to create new travel opportunities.

Skelmersdale Branch
Skelmersdale lost its rail service in 1956, and after its expansion into a new town in the 1960s, various proposals were made to reconnect it to the Merseyrail network. In June 2009, the Association of Train Operating Companies proposed reopening the line from Ormskirk to Skelmersdale as part of a £500million scheme to reinstate 33 stations closed through the Beeching Axe. This plan involved extending the line from Ormskirk railway station with a 3 mi single track towards Rainford Junction, costing an estimated £31million. In December 2012, Merseytravel and West Lancashire Council funded a Network Rail study on potential routes and costs, contributing £50,000 and £100,000 respectively. By 2014, the focus shifted to reopening the Skelmersdale Branch from Upholland to Skelmersdale town centre.

In January 2017, Lancashire County Council announced the preferred site for the railway terminal station was the former Glenburn Sports College and Skelmersdale College's West Bank Campus. The Liverpool City Region Combined Authority's Long Term Rail Strategy of October 2017 noted ongoing efforts by Merseytravel, Lancashire County Council, and Network Rail to extend Merseyrail from Kirkby to Skelmersdale, considering third rail electrification. The government gave assurances in April 2020 that the Skelemersdale link would be constructed. However, in July 2022, the Department for Transport rejected the Strategic Outline Business Case, suggesting improved bus links to the Kirkby–Wigan rail line as a more cost-effective solution.

Outer Rail Loop
The Orbital Outer Rail Loop was part of the original Merseyrail plans in the 1970s, designed to circle the outer edges of Liverpool using existing rail lines. Liverpool’s semi-circular layout has the city centre on its western edge by the River Mersey. The loop’s western section, paralleling the river through the city centre, was the only part completed and now forms part of the Northern Line.

The concept of using the former Cheshire Lines Committee's North Liverpool Extension Line through the eastern suburbs dates back to before WWII. The proposal was a 'belt' line using the former Liverpool Overhead Railway, which ran along the river front, as its western section. The idea evolved in the 1960s into the Outer Rail Loop, a rapid-transit line combining new and existing electrified lines with a tunnel under the city centre. This would have allowed passengers from eastern and southern mainline routes to transfer at two parkway interchange stations, including Liverpool South Parkway, which opened three decades after the original proposal. The proposal would have allowed passengers to reach suburbs without entering the city centre, easing congestion at Lime Street station.

The Outer Loop aimed to connect eastern suburbs like Gateacre, Childwall, Broad Green, Knotty Ash, West Derby, Clubmoor, and Walton with the city centre. The final plan featured two sub-loops for the northern and southern suburbs, providing direct city centre access from the east. However, the eastern section was canceled in the late 1970s due to delays, cost overruns, and political opposition, with only the western section completed. The eastern section now forms the Liverpool Loop Country Park, a walking and cycling trail.

The project was abandoned as a working proposal by Merseytravel in the 1980s. Much expense was incurred in constructing a large bridge taking the M62 motorway over the eastern section and the construction of header tunnels south of Liverpool Central station. The route is still largely intact, complete with bridges, although now the eastern section mainly forms the Liverpool Loop Country Park – a walking and cycling trail through the suburbs.

The key components of the Loop were as follows:


 * West Section: Existing Northern Line from Sandhills (later Aintree) to Hunts Cross, including the costly Link Line tunnel under the city centre.
 * East Section: Former CLC North Liverpool Extension Line from Hunts Cross to Aintree, now a country park.
 * North Section: Originally from Walton to Kirkdale, later from Aintree to Bootle via the North Mersey Branch, with the latter still used for maintenance trains.
 * Central Section: From Central station to Broad Green, dividing the loop into north and south sub-loops, with a proposed but unrealized Edge Hill Spur scheme. A major junction was to have been formed with the eastern section of the Outer Loop with a six platform underground station to be named Rocket under the car park of the Rocket pub near the M62/Queens Drive road junction.

The loop was to use a double track with a 750VDC third rail system. Although not officially revived, the route remains safeguarded, with occasional calls to revive parts of it, such as the stretch from Hunts Cross to Gateacre. Recent strategy documents have mentioned reopening the North Mersey Branch for passenger service between Bootle and Aintree with stations to serve Ford and Girobank.

Edge Hill Spur (reusing tunnels)
In the 1960s and early 1970s, the Edge Hill Spur scheme was proposed to link Liverpool's eastern suburbs with the central underground section of Merseyrail. The plan involved extending the network from Liverpool Central Station to Edge Hill Station using existing freight tunnels. Although the scheme was eventually dropped, construction of junctions and two header tunnels south of Central station was completed during the Northern Line tunnel construction to allow for the Spur's future development.

The Edge Hill Spur aimed to connect the City Line branches from Liverpool's east into the electrified Merseyrail network, enhancing network integration and connectivity. By diverting local trains entering from the east underground, it would have freed platform space at Lime Street station for mid and long-haul routes. Initially, the plan was to reuse the 1829 Wapping freight tunnel, creating two new single-track tunnels branching from the Northern Line at Liverpool Central South Junction. This would have provided access to Edge Hill via the historic Cavendish cutting, built for the 1830 Liverpool and Manchester Railway. A flyover east of Edge Hill Station would have connected to the City Line, although this flyover has since been demolished.

In the early 1970s, Liverpool City Council proposed an alternative route, which was adopted. This revised plan included constructing a new underground station near Liverpool University, behind the Student's Union building in Mount Pleasant. The new tunnels would curve north, passing beneath the mainline Lime Street station approach and accessing Edge Hill via the Waterloo/Victoria Tunnel. This route would emerge at Edge Hill Station on the north side of the main lines, eliminating the need for a flyover.

Although the 1975 Merseyside Metropolitan Railway Act granted powers to build this line, construction was postponed due to financial cutbacks and political opposition, which also halted the Outer Rail Loop project. The eastern part of Liverpool has suffered from reduced connectivity ever since. Attempts to revive the project in the mid-1980s were found to be financially unviable. After the collapse of the Merseytram scheme in 2006, there were renewed proposals to revive the Spur, and the route remains safeguarded in MerseyTravel's 30-year plan.

In 2016, Liverpool's then mayor Joe Anderson proposed resurrecting the Edge Hill Spur with a new station at Paddington Village, as part of expanding Liverpool's Knowledge Quarter. A feasibility study commissioned in May 2016 found that the Wapping Tunnel, though suffering from flooding in places, was in good condition and the concept of reopening it was viable with some remedial work required.
