The Glasgow Underground Railway is opened by the Glasgow District Subway Company.

The Glasgow Subway is an underground light metro system in Glasgow, Scotland. Opened on 14 December 1896, it is the third-oldest underground metro system in the world after the Metropolitan Railway in London, 1863, and the Budapest Metro, 1896. It is also one of the very few railways in the world with a track running gauge of 4 ft. Originally a cable railway, the subway was later electrified, but the double-track circular line has never been expanded. The line was originally known as the Glasgow District Subway, and was thus the first mass transit system to be known as a "subway"; it was later renamed Glasgow Subway Railway. In 1936 it was renamed the Glasgow Underground. Despite this rebranding, many Glaswegians continued to refer to the network as "the Subway". In 2003, the name "Subway" was officially readopted by its operator, Strathclyde Partnership for Transport (SPT).

December 14 is the 348th day of the year in the Gregorian calendar; 17 days remain until the end of the year.
