London – UK: Underground
Image by wallyg
The London Underground is an all-electric metro railway system that covers much of the conurbation of Greater London and some neighbouring areas. It is the world’s oldest underground system, and is the largest in terms of route length. Service began on January 10, 1863 on the Metropolitan Railway; most of that initial route is now part of the Hammersmith & City Line. Despite its name, about 55% of the network is above ground. Popular local names include the Underground and, more colloquially, the Tube, in reference to the cylindrical shape of the system’s deep-bore tunnels. The Underground currently serves 274 stations and runs over 408 km (253 miles) of lines. There are also a number of former stations and tunnels that are now closed. In 2004–2005, total passenger journeys reached a record level of 976 million, an average of 2.67 million per day.
The origins of the roundel, in earlier years known as the ‘bulls-eye’ or ‘target’, are more obscure. While the first use of a roundel in a London transport context was the 19th-century symbol of the London General Omnibus Company — a wheel with a bar across the centre bearing the word GENERAL — its usage on the Underground stems from the decision in 1908 to find a more obvious way of highlighting station names on platforms. The red disc with blue name bar was quickly adopted, with the word "UNDERGROUND" across the bar, as an early corporate identity. The logo was modified by Edward Johnston in 1919.
Each station displays the Underground roundel, often containing the station’s name in the central bar, at entrances and repeatedly along the platform, so that the name can easily be seen by passengers on arriving trains.
The roundel has been used for buses and the tube for many years, and since TfL took control it has been applied to other transport types (taxi, tram, DLR, etc.) in different colour pairs. The roundel has to some extent become a symbol for London itself.
