Today marks 125 years of operation of the Glasgow subway.

To celebrate, the city's circular transport hub are hosting Capital One Radio DJ Katy Johnston, who will perform a set at their Buchanan Street stop from 12pm to 2pm.

They are also promising to give away Subway 'goodies'. 

Glasgow Subway wrote on their official Twitter page: "It's our birthday... 125 today To celebrate our pal @katyjjo from @CapitalScotland will be doing an exclusive DJ set at Buchanan Street 12-2 today.

"We'll also be giving away loads of Subway goodies so come on down!" 

The Subway's inner and outer circles have been taking Glaswegians around the city since 1896, and is one of the oldest underground systems in the world.
