R (New York City Subway service) in the context of "BMT Broadway Line"

The Jackson Heights–Roosevelt Avenue/74th Street station is a New York City Subway station complex served by the IRT Flushing Line and the IND Queens Boulevard Line. Located at the triangle of 74th Street, Broadway, and Roosevelt Avenue in Jackson Heights, Queens, it is served by the 7, E, and F trains at all times; the R train at all times except late nights; the M train on weekdays during the day; and the <F> train during rush hours in the reverse peak direction.

The complex consists of two stations: the elevated station at Broadway–74th Street, built for the Interborough Rapid Transit Company (IRT) and Brooklyn Rapid Transit Company (BRT), and the underground IND station at Jackson Heights–Roosevelt Avenue, built for the Independent Subway System (IND). The elevated station was built as part of the Dual Contracts and opened on April 21, 1917; the station was also served by the BRT and its successor, the Brooklyn–Manhattan Transit Corporation, until 1949. The IND station opened on August 19, 1933, and was the terminus of the Queens Boulevard Line until 1936. Escalators between the two stations were installed in the 1950s, and the complex was substantially rebuilt between 2000 and 2005.

Bay Ridge is a neighborhood in the southwest corner of the New York City borough of Brooklyn. It is bounded by Sunset Park to the north, Dyker Heights to the east, the Narrows and the Belt Parkway to the west, and Fort Hamilton Army Base and the Verrazzano–Narrows Bridge to the south. The section of Bay Ridge south of 86th Street is sometimes considered part of a sub-neighborhood called Fort Hamilton.

Bay Ridge was formerly the westernmost portion of the town of New Utrecht, comprising two smaller villages: Yellow Hook to the north and Fort Hamilton to the south. Yellow Hook was named for the color of the soil and was renamed Bay Ridge in December 1853 to avoid negative connotations with yellow fever at the time; the name Bay Ridge was chosen based on the local geography. Bay Ridge became developed as a rural summer resort during the mid-19th century. The arrival of the New York City Subway's Fourth Avenue Line (present-day R train) in 1916 led to its development as a residential neighborhood. Bay Ridge is known for its Norwegian community, though it also has Irish, Italian, Arab and Greek communities, with smaller populations of Chinese, Russian, and Eastern Europeans.

The Brooklyn–Manhattan Transit Corporation (BMT) was an urban transit holding company, based in Brooklyn, New York City, United States, and incorporated in 1923. The system was sold to the city in 1940. Today, together with the IND subway system, it forms the B Division of the modern New York City Subway.

The original BMT routes form the J/Z, L, M, N, Q, R and W trains, as well as the Franklin Avenue Shuttle, with the IND B and D using BMT trackage in Brooklyn. The M train enters the IND via the Chrystie Street Connection after crossing the Williamsburg Bridge. The Q, along with some rush-hour N trains enter the IND from the BMT 63rd Street Line. The R train enters the IND via the 60th Street Tunnel Connection.

The Times Square–42nd Street station is a major New York City Subway station complex located under Times Square, at the intersection of 42nd Street, Seventh Avenue, and Broadway, in Midtown Manhattan. The complex allows free transfers between the IRT 42nd Street Shuttle, the BMT Broadway Line, the IRT Broadway–Seventh Avenue Line and the IRT Flushing Line, as well as to the IND Eighth Avenue Line a block west at 42nd Street–Port Authority Bus Terminal. The complex is served by the 1, 2, 3, 7, N and Q trains at all times, the W train during weekdays; the R and 42nd Street Shuttle (S) trains at all times except late nights; and <7> trains during rush hours in the peak direction. A free passageway from the shuttle platform to the 42nd Street–Bryant Park/Fifth Avenue station, served by the 7, <7>​​, B, ​D, ​F, <F>, and ​M trains, is open during the day from 6 a.m. to 12 a.m.

The present shuttle platforms were built for the Interborough Rapid Transit Company (IRT) as a local station on the city's first subway line, which was approved in 1900. The station opened on October 27, 1904, as one of the original 28 stations of the New York City Subway. As part of the Dual Contracts between the IRT and the Brooklyn–Manhattan Transit Corporation (BMT), the Broadway–Seventh Avenue Line platforms opened in 1917, followed by the Broadway Line platforms in 1918 and the Flushing Line platforms in 1928. The original platforms were also reconfigured to serve the shuttle. The complex has been reconstructed numerous times over the years. The free transfer between the IRT and BMT opened in 1948, while the transfer to the IND station was placed within fare control in 1988. The complex was placed on the National Register of Historic Places in 2004. In the early 21st century, the shuttle station was reconfigured.
