What is the former name of the rail service to which the Northern City Line belongs?
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.
Main North railway line, New South Wales The Main North Line (also known as the Great Northern Railway) is a major railway in New South Wales, Australia. It runs through the Central Coast, Hunter and New England regions. The line was the original main line between Sydney and Brisbane, however this required a change of gauge at Wallangarra. As of 1988, the line is now closed north of Armidale, with the main route between Sydney and Brisbane now the North Coast line.
