Platform gap fillers in Hong Kong

Platform gap fillers on the metro systems like the New York City Subway or on train stations in Hong Kong are movable platform edge extensions at stations where the curvature of the platform creates a significant gap between the platform and subway car door.

In New York City[edit]

The Interborough Rapid Transit Company's first cars were built with only two doors on each side, at the extreme ends of the car, lining up with the curved platforms so as not to leave a wide gap between the train and the platform. When the IRT modified existing cars and ordered new cars with a middle door, gap fillers were needed because the middle door was not near the platform. After the City of New York bought the IRT in 1940, new car designs (starting with the R12) had the end doors away from the extreme ends of the carbody, which also required the use of gap fillers at certain stations.

Stations equipped[edit]

IRT stations with gap fillers are:


The 2004 replacement gap fillers were manufactured by Jaygo Incorporated and Manning & Lewis Engineering.[5][6]
