Liverpool Central railway station in Liverpool, England, forms a central hub of the Merseyrail network, being on both the Northern Line and the Wirral Line.
 The station is located underground on two levels, below the site of a former mainline terminus.
 It is the busiest station in Liverpool, though considerably smaller than Lime Street station, the mainline terminus, and the busiest station to operate fully the Merseyrail network.
 In terms of passenger entries and exits between April 2010 and March 2011, Liverpool Central is the seventh-busiest station outside London.
 The station is the busiest underground station outside London serving 40,000 people daily.
 The station in passengers per platform is the busiest underground railway station in the United Kingdom at 5,217,547 per platform per annum and laying third in all stations, underground or overground.
The North West Route Utilisation Strategy (NWRUS) is a Route Utilisation Strategy, published by Network Rail in May 2007.
 It was the fifth RUS to be produced.
 It was included in a map published by the Office of Rail Regulation as established in May 2007.
 It was the first of no fewer than 5 RUSs which cover specific routes in the north-west of England; the others are the Lancashire & Cumbria RUS (published August 2008), the Yorkshire & Humber RUS (published July 2009), the Merseyside RUS (published March 2009), and the West Coast Main Line RUS (now scheduled for publication in summer 2011).
 In particular it "broadly covers the Manchester journey to work area, the City lines into Liverpool Lime Street and routes from Manchester to Kirkby, Southport and Blackpool", corresponding to Network Rail's then Route 20 - North West Urban.
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.
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:
