Jefferson Avenue is a Staten Island Railway station between the neighborhoods of Grant City, Staten Island, New York and Dongan Hills, Staten Island, New York. It is located on an embankment at Jefferson Avenue and Railroad Avenue on the main line. This station has two side platforms. There is no station house and the only exit is at the northeast end, which leads to Jefferson Avenue. This is the only station on the SIR to be named for a street rather than for the neighborhood it serves, like most New York City Subway stations.
