East Coast Main Line
Videos
The East Coast Main Line (ECML) is a 393-mile long (632 km) electrified railway between its southern terminus at London King's Cross station and Edinburgh Waverley via Peterborough, Doncaster, York, Darlington, Durham and Newcastle. The line is a key transport artery on the eastern side of Great Britain running broadly parallel to the A1 road. The main line acts as a 'spine' for several diverging branches, serving destinations such as Cambridge, Leeds, Hull, Sunderland and Lincoln, all with direct services to London. In addition, a few ECML services extend beyond Edinburgh to serve Glasgow Central, although the principal London-Glasgow route is the West Coast Main Line (WCML).
