As part of its development, what is now the Flushing Line was extended one stop East, from
Vernon–Jackson Avenues, which opened in 1915, to Hunters Point Avenue on February 15, 1916. Later that year it would again be extended to
Court Square–23rd Street station. The city government took over the IRT's operations on June 12, 1940. The IRT routes were given numbered designations in 1948 with the introduction of
"R-type" rolling stock, which contained
rollsigns with numbered designations for each service. The route from Times Square to Flushing became known as the
7. In 1949, the
New York City Board of Transportation announced that the Flushing Line platforms would be lengthened to 11 IRT car lengths; the platforms were only able to fit nine 51-foot-long IRT cars beforehand. The platforms at the station were extended in 1955–1956 to accommodate 11-car trains. However, nine-car trains continued to run on the 7 route until 1962, when they were extended to ten cars. == Station layout ==
