The Glasgow City and District Railway was a sub-surface railway line in Glasgow, Scotland, built to connect suburban routes east and west of the city, and to relieve congestion at the Queen Street terminus. Construction of the cut-and-cover route, only the fourth such in Great Britain, was formidably complex, but the line opened in 1886. It was steam operated, leading to complaints about smoky conditions. It had a four-platform low level station at Queen Street, and was heavily used. The line was electrified in 1960 and today forms the central part of the North Clyde electric railway network.
