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.
