North Clyde Line
The North Clyde Line is defined by Network Rail as the Glasgow North Electric Suburban line.
It links the towns of Airdrie and Coatbridge on the eastern edge of Greater Glasgow to the northern Clyde coast, mainly to the towns of Helensburgh and Balloch. There are also two spurs from the line which serve the town of Milngavie, and the Glasgow suburb of Springburn. Westwards between Partick and Dalmuir, the line splits into two routes via Singer and Yoker. West Highland Line services operate along the North Clyde Line between Craigendoran Junction and Westerton.
The line runs through central Glasgow - the principal station on the line is Glasgow Queen Street (Low Level). The section through the city centre largely runs in tunnels between High Street and the former Finnieston station. This is the oldest stretch of underground railway in Glasgow, opened as the Glasgow City and District Railway in 1886, it predated the Glasgow Subway by some ten years.
