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.
34-534: Finch West is a subway station on the Line 1 Yonge–University of the Toronto subway . It is located under Keele Street , north of Finch Avenue West . When Line 6 Finch West opens in the fourth quarter of 2024, it will serve as the eastern terminus of that line. The station is underground and parallel to Keele Street just north of Finch Avenue West. Nearby landmarks include Fountainhead Park. Industrial areas lie to
68-401: 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
102-607: 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
136-669: 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. 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
170-735: 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
204-884: 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
238-598: 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
272-765: 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
306-479: The Toronto Transit Commission (TTC). It was the country's first subway system: the first line was built under Yonge Street with a short stretch along Front Street and opened in 1954 with 12 stations. Since then, the system has expanded to become Canada's largest in terms of number of stations and its second-busiest , with an average of 915,000 passenger trips each weekday recorded during
340-862: 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
374-524: The Line 6 connection was included as part of the station's design, with knockout panels provided to ease construction. The line curves off the Keele Street alignment a short distance to the north and south of the station, veering northwest to York University station and swings broadly at a 90° angle southeast to Downsview Park station . To reverse trains, there is both a crossover at the south end of

The 36 Finch West bus route splits here to help maintain reliable service in light of the Finch West LRT construction west of this station. The 36 Finch West and 939B Finch Express enter via Tangiers Road. When the subway is closed, buses do not enter the station and bypass Tangiers Road. Buses serving Keele Street do not enter
442-407: The design team to integrate sculptural concrete forms with the supporting columns within the entrance buildings, on double-height platform columns, and under the bus canopy. Landscape design of the station was by Janet Rosenberg & Studio . In March 2006, The Globe and Mail reported that real estate development companies belonging to the family of Ontario Finance Minister Greg Sorbara owned
476-654: The east side of Keele and south side of the hydro corridor was demolished to make way for the bus platform area. A new fire station replaced this building on the opposite side of Keele Street. This station, along with the five other TYSSE stations, were the first to be opened without fare collectors, although collector booths were installed as per original station plans. It was also among the first eight stations to discontinue sales of legacy TTC fare media (tokens and tickets). Presto vending machines were available at its opening to sell Presto cards and to load funds or monthly passes onto them. On May 3, 2019, this station became one of
510-410: The east, James Cardinal McGuigan Catholic High School to the west and York University is to the northwest, served by the next station north on the line. The main entrance is located on the east side of Keele Street with the secondary entrance on the west side. The exterior of the main entrance features a striped, barcode cladding along with colourful tiling and windows. The concourse level around
544-643: 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
578-423: The faregates also features the barcode motif. An elevated substation facility is in the attic level of the main building and overhangs the main entrance as a canopy. The main entrance is highlighted by a glowing panel attached to the canopy. There is a cool roof over this entrance and a green roof over the elevated substation box. The six-bay bus terminal has a waiting area inside the building. Bicycle parking at
612-492: The first ten stations to sell Presto tickets via Presto vending machines. Line 6 Finch West, expected to open in 2024, will have its eastern terminus at Finch West station. The station will be located 11 m (36 ft) underground with an east–west orientation under Finch Avenue West, passing over the crossover box structure for Line 1 subway trains. The station will have a centre island platform , which will be at least 98 m (322 ft) long to handle LRV trains. West of
646-558: The fourth quarter of 2017. There are a total of 70 operating stations with an additional 60 under construction – 28 of which will be street-running light rail transit (LRT) stops – and 5 former stations. The subway system encompasses three lines and 70 stations on 70.5 kilometres (43.8 mi) of route. As of 2024 , 55 of the 70 stations are accessible, with plans originally set to ensure all stations were accessible by 2025 ; however, in September 2024, it
680-428: 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
714-604: 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 ,

#1732780939317748-524: 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
782-552: The official groundbreaking ceremony was held for the Toronto–York Spadina Subway Extension (TYSSE), and major tunnelling operations started in June 2011. The project, including Finch West station, was initially expected to be completed by the second quarter of 2015 but was delayed to the fourth quarter of 2016; ultimately, the station opened on December 17, 2017. In mid-2015, the former Toronto Fire Station 141 on
816-480: The platform, there is a ramp carrying Line 6 to street level. At the top of the ramp, there is a double crossover. As part of the project, a new two-storey station entrance will be built at the southeast corner of the Keele–Finch intersection, with an underground tunnel to link the new line to the existing Line 1 station. Two skylights will also be built in the median to allow light into the station below. Provision for
850-602: The properties just south of the intersection of Finch Avenue West and Keele Street, according to land registry documents and corporate records. The article said that these companies would benefit from higher real estate values due to the subway extension. Sorbara was the Liberal Member of Provincial Parliament for Vaughan, and was a major advocate for the Toronto–York Spadina Subway Extension, which includes Finch West station. On November 27, 2009,
884-432: The station and a storage track to the north. The centre track structure at this station was constructed in a unique manner from ones at other stations, which were built fully using the cut-and-cover method with columns between the tracks. At this station, after the mainline tunnels were bored and the ground excavated for the station structure, the inner sides of the tunnel liners north of the station box were removed, and
918-461: The station but stop on-street, and a transfer is required for connection. The following routes serve the station: After the opening of Line 6 Finch West, the above bus connections will be replaced by the following routes (proposed as of November 2023): List of Toronto subway stations The Toronto subway is a system of three underground, surface, and elevated rapid transit lines in Toronto and Vaughan , Ontario, Canada, operated by
952-459: The station includes 100 secure plus 13 short-term spaces. North of the station is a parking lot for 347 cars plus a pick-up-and-drop-off facility. The station was designed by a consortium of architects and engineers, Spadina Group Associates – including All Design (headed by British architect Will Alsop ) and IBI Group . Scottish artist Bruce McLean – a frequent collaborator with Will Alsop – worked with
986-663: 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
1020-501: 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,
1054-434: 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

1088-590: 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
1122-555: 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
1156-551: Was reported this goal would not be met until 2026. Line 3 Scarborough , a light metro line with six stations, was permanently closed in July 2023. As of September 2024, three new lines are under construction, two light rail lines and one subway line: Island platform The historical use of island platforms depends greatly upon the location. In the United Kingdom the use of island platforms on twin-track routes
