The Glasgow Central Railway was a railway line built in Glasgow, Scotland by the Caledonian Railway, running in tunnel east to west through the city centre. It was opened in stages from 1894 and opened up new journey opportunities for passengers and enabled the Caledonian Railway to access docks and industrial locations on the north bank of the River Clyde. An intensive and popular train service was operated, but the long tunnel sections with frequent steam trains were smoky and heartily disliked.

The Caledonian Railway (CR) was a major Scottish railway company. It was formed in the early 19th century with the objective of forming a link between English railways and Glasgow. It progressively extended its network and reached Edinburgh and Aberdeen, with a dense network of branch lines in the area surrounding Glasgow. It was absorbed into the London, Midland and Scottish Railway in 1923. Many of its principal routes are still used, and the original main line between Carlisle and Glasgow is in use as part of the West Coast Main Line railway.
