Question: What railway routes connecting two major cities in the North West of England are included in the City Line?

full_context: Document 1: West Coast Main Line: The West Coast Main Line (WCML) is one of the most important railway corridors in the United Kingdom, connecting the major cities of London, Birmingham, Glasgow, Liverpool and Manchester. It is one of the busiest mixed-traffic railway routes in Europe, carrying a mixture of intercity rail, regional rail, commuter rail and rail freight traffic. The core route of the WCML runs from London to Glasgow, with branches diverging to Birmingham, Manchester and Liverpool, totalling a route mileage of 700 mi . Services from London to North Wales and Edinburgh also run via the WCML; however the main London-Edinburgh route is the East Coast Main Line. In addition, several sections of the WCML form part of the suburban railway systems in London, Birmingham, Manchester and Glasgow, with many more smaller commuter stations, as well as providing links to more rural towns.
Document 2: Red Line (MBTA): The Red Line is a rapid transit line operated by the Massachusetts Bay Transportation Authority (MBTA). It runs roughly northwest-to-southeast across Cambridge and Davis Square in Somerville – from Alewife in North Cambridge to Kendall/MIT in Kendall Square – with a connection to commuter rail at Porter. It then crosses over the Longfellow Bridge into downtown Boston, where it connects with the Green Line at Park Street, the Orange Line at Downtown Crossing, the Silver Line at South Station, as well as Amtrak and commuter rail at the South Station surface terminal before passing through South Boston and Dorchester. South of JFK/UMass in Dorchester, it splits into two branches terminating at Braintree and Ashmont stations; transfers to commuter rail are again possible at JFK/UMass, Quincy Center, and Braintree. From Ashmont, passengers may continue to Mattapan via the Ashmont–Mattapan High Speed Line, a 2.6 mi light rail line.
Document 3: Hest Bank North Junction: Hest Bank North Junction is a railway junction in Lancashire, England, where the Morecambe Branch Line joins the former London and North Western Railway (LNWR) line (now the West Coast Main Line (WCML)) in the down direction between Lancaster and Carnforth. It is also known as Morecambe North Junction. This line is currently being considered to become a community railway. Hest Bank railway station was situated here until its closure on 3 February 1969. Little trace of the old station remains, the platforms having been demolished prior to the electrification of the line in 1973. It is also the only location on the entire 401 mile (643 km) WCML where the coastline and Irish Sea is visible from the railway.
Document 4: Liverpool Lime Street railway station: Liverpool Lime Street is a terminus railway station, and the main station serving the city centre of Liverpool. Opened in August 1836, it is the oldest grand terminus mainline station still in use in the world. A large building constructed in the Renaissance Revival style fronts the station. A branch of the West Coast Main Line from London Euston terminates at the station, as well as TransPennine Express trains and other train services. The underground Lime Street Wirral Line station on the Merseyrail network is accessed via the main terminus. Lime Street is the largest and oldest railway station in Liverpool, and is one of 18 stations managed by Network Rail.
Document 5: Northern City Line: The Northern City Line is a branch railway and commuter line in England, which runs from Moorgate to Finsbury Park in London with services running beyond. It is part of the Great Northern Route services and operates as the south-eastern branch of the East Coast Main Line (ECML). It is underground from Moorgate to Drayton Park in Highbury from which point it runs in a cutting until joining the ECML south of Finsbury Park. Its stations span northern inner districts of Greater London southwards to the City of London, the UK's main financial centre. Since December 2015 the service timetable has been extended to run into the late evenings and at weekends, meeting a new franchise commitment for a minimum of 6 trains per hour until 23:59 on weekdays and 4 trains per hour at weekends.
Document 6: Liverpool–Manchester lines: There were once four direct railway routes between Liverpool and Manchester in the North West of England. There are now only two remaining direct railway routes between the two cities. One line, the now northern route, is fully electric and the other, the southern route, is a diesel only line. A third line which is further north has been split with the western section electric and the eastern section diesel operation, requiring a passenger change between the two cities. The fourth route, the most southerly, is largely abandoned east of Warrington with the remaining section mostly catering for freight trains. The remaining two direct routes are:
Document 7: British Rail Class 304: The British Rail Class 304 electric multiple units were built for suburban use on the first phases of the West Coast Main Line electrification between Crewe and Manchester/Liverpool/Rugby. Originally classed as AM4 units, they later became Class 304 under the TOPS numbering system, and could be found in operation over most of the West Coast Main Line. The units conformed to the 1959-design for alternating current (AC) electrical multiple units, and were externally very similar to the Class 305, Class 308 and the 1,200 V direct current (DC) Class 504 units. No units survived into preservation, and all units were eventually scrapped.
Document 8: Rossett railway station: Rossett was a minor railway station located on the Great Western Railway's Paddington to Birkenhead line several miles north of Wrexham in Wales. The route is still open today as part of the Shrewsbury to Chester Line. Originally, there was a level crossing just north of the platforms but this has been reduced to the status of a foot and cycleway crossing. To the south of the station there were once goods loops on both sides of the line as well as extensive sidings on the east side. Part of the old Up (southbound) platform still survives. The double track on the Wrexham to Chester section was singled in 1983 but has been redoubled between Rossett and Saltney, with work finally completed in April 2017 (a year later than scheduled).
Document 9: East Coast Main Line: The East Coast Main Line (ECML) is a 393 mi major railway link between London and Edinburgh via Peterborough, Doncaster, Wakefield, Leeds, York, Darlington and Newcastle, electrified along the whole route. Services north of Edinburgh to Aberdeen and Inverness use diesel trains. The main franchise on the line is operated by Virgin Trains East Coast.
Document 10: Cumbrian Coast line: The Cumbrian Coast line is a rail route in North West England, running from Carlisle to Barrow-in-Furness via Workington and Whitehaven. The line forms part of Network Rail route NW 4033, which continues (as the Furness line) via Ulverston and Grange-over-Sands to Carnforth, where it connects with the West Coast Main Line.
Document 11: Radio City (Liverpool): Radio City (previously known as 96.7 City FM and 194 Radio City) is a British Independent Local Radio station, based in Liverpool, and serving Merseyside, Cheshire and North Wales. The station is owned & operated by Bauer Radio and forms part of Bauer's City 1 network of stations.
Document 12: Disused railway stations on the Cornish Main Line: There are seventeen disused railway stations on the Cornish Main Line between Plymouth in Devon and Penzance in Cornwall, England. The remains of nine of these can be seen from passing trains. While a number of these were closed following the so-called "Beeching Axe" in the 1960s, many of them had been closed much earlier, the traffic for which they had been built failing to materialise.
Document 13: City Circle: The City Circle is a system of largely underground passenger railway lines located in the Sydney central business district, in New South Wales, Australia, that make the core of Sydney's passenger railway network. The lines are owned by RailCorp, a State government agency, and operated under Transport for NSW's Sydney Trains brand. Despite its name, the City Circle is of a horseshoe shape, with trains operating in a U-shaped pattern. The constituent stations of the Circle are (clockwise): Central, Town Hall, Wynyard, Circular Quay, St James, Museum and back to Central.
Document 14: City Line (Merseyrail): The City Line is the name given to local rail routes out of Liverpool Lime Street railway station. It appears on maps of the Merseyrail network as red, and covers the Liverpool–Wigan line as well as the two routes of the Liverpool–Manchester lines. Although it is branded under the Merseyrail name, the routes are operated by Northern on behalf of Merseytravel rather than by the Merseyrail franchise.
Document 15: Pulford railway station: Pulford was a short-lived minor railway station located on the Great Western Railway's Paddington to Birkenhead line several miles south of Chester, just inside the English border. The route is still open today as part of the Shrewsbury to Chester Line. Nothing now remains at the site except for a Pulford AHB level crossing. The double track on the Wrexham to Chester section was singled in 1983 but was redoubled through here in 2017 as part of a £40 million upgrade of the route.
