Subway (underpass) in the context of "Chancery Lane tube station"

An island platform (also center platform (American English) or centre platform (British English)) is a station layout arrangement where a single platform is positioned between two tracks within a railway station, tram stop or transitway interchange. Island platforms are sometimes used between the opposite-direction tracks on twin-track route stations as they are cheaper and occupy less area than other arrangements. They are also useful within larger stations, where local and express services for the same direction of travel can be accessed from opposite sides of the same platform instead of side platforms on either side of the tracks, simplifying and speeding transfers between the two tracks.

The historical use of island platforms depends greatly upon the location. In the United Kingdom the use of island platforms on twin-track routes is relatively common when the railway line is in a cutting or raised on an embankment, as this makes it easier to provide access to the platform without walking across the tracks.

Queensway, in Birmingham, England, most often refers to the Queensway Tunnel, a 1,798 feet (548 m) long road tunnel in the centre of the city. The tunnel forms part of the designated A38, which locally is a major carriageway that cuts through Birmingham city centre. "Queensway" as a suffix is also the name of several other roads and circuses in the city (such as Smallbrook Queensway); all these roads including the tunnel collectively made up what was once called the Inner Ring Road, an orbital dual carriageway which has now been dismantled.

The old Inner Ring Road, which was also referred to as the "Queensway" and designated as the A4400 road, was completed and opened in 1971. Described as an "urban motorway" (although it was not officially designated as a motorway), it featured largely grade separated junctions and most of them allowed vehicles staying on the road to pass over or under those using the junction. Pedestrians were kept physically separate from vehicular traffic and used subways to cross the ring road. Although seen as revolutionary when first opened, the 'Concrete Collar', as it became known, was viewed by council planners as an impenetrable barrier for the expansion of the city centre. By the 1990s, changes were made to the road as the council sought to improve pedestrian links, and vehicular movements were increasingly shifted out to the Middleway. The Inner Ring Road was effectively dismantled in the early 2000s, with many of its roads having been rebuilt and downgraded to surface-level streets, resulting in them resembling city streets far more. The Queensway Tunnel and St Chad's Tunnel, as well as the Lancaster Circus and Suffolk Street flyovers, are remaining relics of the ring road and make up most of the present A38 carriageway in this area.

South Kensington is a London Underground station in the district of South Kensington, south west London. It is served by three lines: Circle, District and Piccadilly. On the Circle and District lines the station is between Gloucester Road and Sloane Square stations, and on the Piccadilly line it is between Gloucester Road and Knightsbridge stations. The station is located in London fare zone 1. The main station entrance is located at the junction of Old Brompton Road (A3218), Thurloe Place, Harrington Road, Onslow Place and Pelham Street. Subsidiary entrances are located in Exhibition Road giving access by pedestrian tunnel to the Natural History, Science and Victoria and Albert Museums. Also close by are the Royal Albert Hall, Imperial College London, the Royal College of Music, the London branch of the Goethe-Institut and the Ismaili Centre.

The station is in two parts: sub-surface platforms opened in 1868 by the Metropolitan Railway and the District Railway as part of the companies' extension of the Inner Circle route eastwards from Gloucester Road to Westminster and deep level platforms opened in 1906 by the Great Northern, Piccadilly and Brompton Railway. A variety of underground and main line services have operated over the sub-surface tracks, which have been modified several times to suit operational demands with the current arrangement being achieved in the 1960s. The deep-level platforms have remained largely unaltered, although the installation of escalators in the 1970s to replace lifts improved interchanges between the two parts of the station. Parts of the sub-surface station and the Exhibition Road pedestrian tunnel are Grade II listed.
