The 45th Street station is a local station on the BMT Fourth Avenue Line of the New York City Subway. Located at 45th Street and Fourth Avenue in Sunset Park, Brooklyn, it is served by the R train at all times. The N train also stops here during late nights, and some rush-hour W trains stop here in the peak direction.
The 45th Street station was constructed as part of the Fourth Avenue Line, which was approved in 1905. Construction on the segment of the line that includes 45th Street started on March 15, 1913, and was completed in 1915. The station opened on September 22, 1915, after the opening of the initial portion of the BMT Fourth Avenue Line to 59th Street. The station's platforms were lengthened in 1926–1927, and again during a renovation in 1968–1970.
History
Construction and opening
The 45th Street station was constructed as part of the Fourth Avenue Line, the plan for which was initially adopted on June 1, 1905. The Rapid Transit Commission was succeeded on July 1, 1907, by the New York State Public Service Commission (PSC), which approved the plan for the line in late 1907.
As part of negotiations between New York City, the Brooklyn Rapid Transit Company (BRT), and the Interborough Rapid Transit Company for the expansion of the city's transit network, the line was leased to a subsidiary of the BRT. The agreement, known as Contract 4 of the Dual Contracts, was signed on March 19, 1913. In 1912, during the Dual System negotiations, the construction of an extension of the Fourth Avenue subway from 43rd Street to 89th Street, just south of the 86th Street station, was recommended. The proposal was approved by the Board of Estimate on February 15, 1912. The PSC directed its chief engineer to create plans on June 14, 1912. The two contracts for the extension, Route 11B, were awarded on September 16, 1912, to Degnon Construction Company for a combined $3.8 million (equivalent to $ million in ).
Construction on Route 11B1, the section of the extension between 43rd Street and 61st Street, which includes the 45th Street station, began on March 15, 1913. Originally, this section was planned to have two tracks, but after the connection to the Sea Beach Line was added to the plan during the middle of construction, the plan was changed to four tracks. This section was completed in 1915. The section of the line running through the 45th Street station opened on June 22, 1915, as part of an extension of the subway to Coney Island, which included the Fourth Avenue Line north of 59th Street as well as the entire Sea Beach Line. The line's opening was marked with a competition between two trains heading from Chambers Street station in Manhattan to the Coney Island station, one heading via the West End Line and the other via the Sea Beach Line; the latter got to Coney Island first. However, the 45th and 53rd Street stations remained closed, despite being technically complete, since the stations were being used by a contractor to haul dirt out. The stations opened on September 22, 1915.
Station renovations
1920s
On June 27, 1922, the New York State Transit Commission commissioned its engineers to examine platform-lengthening plans for 23 stations on the lines of the Brooklyn–Manhattan Transit Corporation (BMT), the successor to the BRT, to accommodate eight-car trains. As part of the project, 45th Street's platforms would have been lengthened from to . Though the Transit Commission ordered the BMT to lengthen these platforms in September 1923, no further progress was made until February 16, 1925, when the New York City Board of Transportation (NYCBOT) commissioned its engineers to examine platform-lengthening plans for this and eleven other stations along the Fourth Avenue Line. It estimated the project would cost $633,000 (). The NYCBOT received bids for the project on February 25, 1926. The contract was awarded to the Corson Construction Company for $345,021 (). The extensions opened on August 1, 1927.
1960s
The city government took over the BMT's operations on June 1, 1940. In the 1960s, the New York City Transit Authority (NYCTA) started a project to lengthen station platforms on its lines in Southern Brooklyn to to accommodate 10-car trains. On July 14, 1967, the NYCTA awarded a contract to conduct test borings at eleven stations on the Fourth Avenue Line, including 45th Street, to the W. M. Walsh Corporation for $6,585 () in preparation of the construction of platform extensions. The NYCTA issued an invitation for bids on the project to extend the platforms at stations along the Fourth Avenue Line between this station and Bay Ridge–95th Street on May 3, 1968.
