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.
Blue Line (TRAX) The Blue Line is a light rail line on the TRAX system in the Salt Lake Valley of Utah, in the United States, operated by the Utah Transit Authority (UTA). It is the first line of the TRAX system completed. The line opened on December 4, 1999, one year ahead of schedule after two years of construction. In addition to Salt Lake City, it also serves the communities of South Salt Lake, Murray, Midvale, Sandy and Draper. The line was known as the North/South Line or the Sandy/Salt Lake Line until color names were adopted for each TRAX line in August 2011. An extension of the line to Draper began service on August 18, 2013.
