be easy to change 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. Australia In Sydney, on the Eastern Suburbs Railway and the Epping Chatswood Railway, 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, and Watsonia and Heidelberg on the Hurstbridge line. Canada 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 the Capital Line and Metro Line use island platforms. The Valley Line under construction, utilizes the new low-floor LRT technology, but will only use island platforms on one of the twelve stops along the line. Singapore 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. Gul Circle uses a stacked island platform configuration. The same follows for underground stations, with the exception being Braddell MRT station, Bishan MRT station, Ang Mo Kio 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) United States 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 the system have the same layout. Unused sides of island platforms 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
