25-522: The station has an underground island platform . There are 3 exits, lettered A, B, and C. Exit A is accessible. 39°51′12″N 116°22′17″E  /  39.8532°N 116.3714°E  / 39.8532; 116.3714 This article related to the Beijing Subway is a stub . You can help Misplaced Pages by expanding it . Island platform An island platform (also center platform (American English) or centre platform (British English))

50-401: A bridge or underpass. If an island platform is not wide enough to cope with passenger numbers, typically as they increase, overcrowding can risk people being pushed onto the tracks. In some cases entry to the station is restricted at busier times to reduce risk. Examples of stations where a narrow island platform has caused safety issues include Clapham Common and Angel (rebuilt in 1992) on

75-587: A new side platform opening in December 2022. Some stations of the Glasgow Subway have one island platform and one side platform ( Hillhead , Buchanan Street , and Ibrox ). In Wellington , New Zealand, unused sides can be found at two stations on the Hutt Valley Line : Waterloo and Petone . Waterloo's island platform was reconfigured to be the down side platform when the station was extensively rebuilt in

100-413: 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

125-724: The Capital Line and Metro Line used island platforms until NAIT/Blatchford Market station opened in 2024, the only station with side platforms as of 2024. The Valley Line Southeast uses low-floor LRT technology, but uses island platforms on only one of the 12 stops, Mill Woods . Almost all of the elevated stations in Singapore 's Mass Rapid Transit (MRT) system use island platforms. The exceptions are Dover MRT station and Canberra MRT station , which use side platforms as they are built on an existing rail line, also known as an infill station . The same follows for underground stations, with

150-855: The IRT Seventh Avenue Line and 34th Street – Penn Station on the IND Eighth Avenue Line of the New York City Subway , uses two side platforms for local services with an island in between for express services. The purpose of this atypical design was to reduce unnecessary passenger congestion at a station with a high volume of passengers. Since the IRT Seventh Avenue Line and IND Eighth Avenue Line have adjacent express stations at 42nd Street, passengers can make their transfers from local to express trains there, leaving more space available for passengers utilizing intercity rail at Pennsylvania Station . The Willets Point Boulevard station

175-515: The London Borough of Bromley , south London. It is 7 miles 66 chains (12.6 km) down the line from London Victoria and is situated between Penge East and Beckenham Junction . It takes its name from the nearby Kent House farm, the first house in the historic county of Kent after crossing the Surrey border. The station and most trains that call are operated by Southeastern , as part of

200-629: The London Underground , Union (rebuilt in 2014) on the Toronto subway , and Umeda on the Osaka Municipal Subway . An island platform requires the tracks to diverge around the centre platform, and extra width is required along the right-of-way on each approach to the station, especially on high-speed lines. Track centres vary for rail systems throughout the world but are normally 3 to 5 metres (9 ft 10 in to 16 ft 5 in). If

225-730: The Newport PATH station has the same configuration as Bowling Green—one side platform and one island platform. On the Tokyo Metro , the Ginza Line has a side platform and an island platform at Nihombashi . Likewise, the Namba and Minami-morimachi stations on the Osaka Metro have similar configurations. On JR East, the Yokosuka Line platforms at Musashi-Kosugi feature a similar setup following

250-829: The Werribee Line , Ardeer , Caroline Springs on the Ballaarat Line , Glen Iris , Holmesglen , Jordanville and Syndal on the Glen Waverley Line , and Watsonia and Heidelberg on the Hurstbridge line . In Toronto , 29 subway stations use island platforms (a few in the newer stations on the Bloor–Danforth line , a few on the Yonge–University line and all of the Sheppard line ). In Edmonton , all 18 LRT stations on

275-585: The Bromley South Metro service, while a limited number of Thameslink services also call. Kent House is in Travelcard Zone 4 . The line was opened by the London, Chatham and Dover Railway (LCDR) on 1 July 1863, but the station was not opened until 1 October 1884 and was originally named Kent House (Beckenham) . It lies above street level, where the booking office is situated; there is a subway and stairs to

300-630: The exception being Braddell MRT station , Bishan MRT station , and a few stations on the Downtown line ( Stevens , Downtown , Telok Ayer , Chinatown and MacPherson ) and the Thomson-East Coast line ( Napier , Maxwell , Shenton Way and Marina Bay ) In southern New Jersey and Philadelphia , PATCO uses island platforms in all of its 13 stations, to facilitate one-person train operation . The NYC Subway's Second Avenue Subway features island platforms at all stations. Many other stations in

325-428: The island platform is 6 metres (19 ft 8 in) wide, the tracks must slew out by the same distance. While this requirement is not a problem on a new line under construction, it makes building a new station on an existing line impossible without altering the tracks. A single island platform also makes it quite difficult to have through tracks (used by trains that do not stop at that station), which are usually between

350-587: The late 1980s, with the unused side now facing onto a bus bay. Petone's island platform served the up main line and the suburban loop line until the suburban loop was lifted in the early 1990s. The unused platform now faces onto the station's park-and-ride carpark. Kent House railway station Kent House railway station is on the Chatham Main Line in England, serving part of the Penge and Beckenham areas in

375-580: The line to a larger gauge, by moving the track away from the platform to allow the wider bodied continental rolling stock to pass freely while leaving the platform area untouched. Island platforms are a very normal sight on Indian railway stations. Almost all railway stations in India consist of island platforms. In Sydney , on the Eastern Suburbs Railway and the Epping Chatswood Railway ,

400-472: The local tracks (where the island would be). A common configuration in busy locations on high speed lines is a pair of island platforms, with slower trains diverging from the main line (or using a separate level on the railway's right-of-way ) so that the main line tracks remain straight. High-speed trains can therefore pass straight through the station, while slow trains pass around the platforms (such as at Kent House in London ). This arrangement also allows

425-533: The platform without walking across the tracks. Island platforms are necessary for any station with many through platforms. There are also advantages to building small two-track stations with a single island platform instead of two side platforms. Island platforms allow facilities such as shops, toilets and waiting rooms to be shared between both tracks rather than being duplicated or present only on one side. An island platform makes it easier for disabled travellers to change services between tracks or access facilities. If

450-519: The platforms. On 3 February 1993, an IRA bomb was detonated on a train at the station that was travelling from Victoria to Ramsgate. A warning had been given and everybody was safely evacuated before the explosion but the damage to the carriage was considerable. All services at Kent House are operated by Southeastern using Class 465 and 466 EMUs . The typical off-peak service in trains per hour is: Additional services, including trains between Beckenham Junction and London Blackfriars call at

475-542: 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

500-624: The station during the peak hours. From the December 2024 timetable change the off-peak service between London Victoria and Orpington will double to 4tph on Mondays to Fridays. London Buses routes 194 , 227 and 358 and night route N3 serve the station. Clock House station on the Hayes Line (formerly the Mid-Kent Line) is a short walk from this station, and has trains between London Charing Cross / Cannon Street and Hayes, which are also operated by Southeastern. Beckenham Road tram stop

525-636: The station to serve as a point where slow trains can be passed by faster trains. A variation at some stations is to have the slow and fast pairs of tracks each served by island platforms (as is common on the New York City Subway ; the Broad Street Line of Philadelphia ; and the Chicago Transit Authority 's Red and Purple lines). A rarer layout, present at Mets-Willets Point on the IRT Flushing Line , 34th Street – Penn Station on

550-494: The system have the same layout. Sometimes when the track on one side of the platform is unused by passenger trains, that side may be fenced off. Examples include Hurlstone Park , Lewisham, Sydney and Yeronga, Brisbane . In New York City's subway system , unused sides are located at Bowling Green as well as every express station without express service, such as Pelham Parkway on the IRT Dyre Avenue line. In Jersey City,

575-434: The tracks are above or below the entrance level, the station needs only one staircase and (if disabled accessibility is necessary) one elevator or ramp to allow access to the platforms. If the tracks are at the same level as the entrance, this instead creates a disadvantage; a side platform arrangement allows one platform to be adjacent to the entrance, whereas an island platform arrangement requires both tracks to be accessed by

600-573: The twin tunnels are widely spaced and the tracks can remain at a constant track centres while still leaving room for the island platforms. A slight disadvantage is that crossovers have to be rather long. Examples in Melbourne include West Footscray , Middle Footscray , Albion and Tottenham on the Sunbury line , Kananook on the Frankston Line , Aircraft , Williams Landing and Hoppers Crossing on

625-541: Was renovated to accommodate the high volume of passengers coming to the 1939 World's Fair . Many of the stations on the Great Central Railway in England (now almost entirely closed) were constructed in this form. This was because the line was planned to connect to a Channel Tunnel . If this happened, the lines would need to be compatible with continental loading gauge , and this would mean it would be easy to change
