London underground is the oldest and one of the busiest underground railway networks in the world. When I start thinking about the the history and background of London underground I found it interesting and fascinating. The reason I like it is because, I read some interesting fact about London underground and It took centuries to make a perfect underground.
One thing I notice is all lines are referred by their contemporary names. Many if not all of the lines have however had different names during their existence.
When the underground network was first devised and built, escalators hadn’t been invented, access to all the deeper stations could only practically be made with a lift. I think lift was invented before the escalators. All the deep level stations on the Central, Piccadilly, and Northern lines were originally built for access via elevator, with a spiral emergency staircase built in a secondary smaller vertical shaft.
As the use of the stations increased and escalators became more widely available, most of the busy stations were converted for escalator use.
During the refurbishment of Charing Cross station in the early 1970s when Trafalgar Square and Strand station were combined to form a single station, a large amount of construction work was needed to excavate the vast amount of rock and earth to create the new tunnels. So that this work could take place, a new shaft was sunk.
One of the more interesting experiments with platform-to-surface transportation took place in the second lift shaft situated at Holloway Road on the Piccadilly Line.
Posters displayed on stations have been prominent in the use of works by artists specially commissioned by the Underground. This tradition started in 1908 with the appearance of posters such as Hassell’s “No need to ask a P’liceman”, which depicted a policeman showing a lady the Underground map which had recently been introduced at stations. The tradition continued throughout the 1920s and 1930s with work by such artists as Graham Sutherland, E McKnight Kauffer and many others. The posters became so popular that they have been reproduced for sale to the public as well as revived for publicity purposes.
London Underground is getting interesting day by day. There is an example of World’s Shortest Escalator
