As part of Contract 4 of the
Dual Contracts, between the city and the BRT, a three-track
elevated railway was built above the surface Culver Line from the Fifth Avenue Elevated southeast and south to Coney Island. The Culver Line was operated as a branch of the Fifth Avenue Elevated, with a free transfer at Ninth Avenue to the West End Line into the Fourth Avenue Subway. Avenue X station opened as the line was extended from
Kings Highway at noon on May 10, 1919. This station ceased being the line's terminal with the completion of the line to Coney Island on May 1, 1920. On October 30, 1954, this station began being served by
IND Concourse Express trains operating to
Coney Island–Stillwell Avenue as the connection between the IND South Brooklyn Line at Church Avenue and the BMT Culver Line at Ditmas Avenue opened. BMT Culver Line (
5) trains were truncated to
Ditmas Avenue, the south end of the connection, operating through to Manhattan via the
Nassau Street Loop during the day, and terminating at
Ninth Avenue at other times. This
Culver Shuttle became full-time on May 28, 1959, and was discontinued in 1975. The station was renovated from June 29, 2015 to December 28, 2015 (Manhattan-bound platform) and June 7, 2016 to May 8, 2017 (Coney Island-bound platform with trains bypassing on the center track) as part of a $140 million renewal project on the Culver Line. In May 2018, site specific permanent public artwork created by NYC based American artist
Derek Lerner was installed at this station. The
MTA Arts & Design commissioned art consists of six multi-panel original and unique ink drawings fabricated as laminated glass and installed in platform windscreens. ==Station layout==
