The underground is as synonymous with London as red telephone boxes and the royals.
It is one of the city’s most vital transport links, dating back to the 1800s.
It enables people to travel the length and breadth of the Big Smoke, without battling the traffic above.
While the concept of the underground remains much the same today, there are of, course a few differences.
We scoured the Getty Image archive to find some interesting black-and-white photos of life on the London Underground in the 1920s.
