IRT White Plains Road Line

The first contract for the construction of a subway in New York, Contract 1, was executed on February 21, 1900, between the Board of Rapid Transit Railroad Commissioners and the Rapid Transit Construction Company, organized by John B. McDonald and funded by August Belmont, for the construction of the subway and a 50-year operating lease from the opening of the line. Contract 1 called for the construction of a line from City Hall north to Kingsbridge and a branch under Lenox Avenue and to Bronx Park.[4]

The initial segment of the IRT White Plains Road Line opened on November 26, 1904 between East 180th Street and Jackson Avenue. Initially, trains on the line were served by elevated trains from the IRT Second Avenue Line and the IRT Third Avenue Line, with a connection running from the Third Avenue local tracks at Third Avenue and 149th Street to Westchester Avenue and Eagle Avenue. Once the connection to the IRT Lenox Avenue Line opened on July 10, 1905, trains from the newly opened IRT subway ran via the line.[5][6][7] Elevated service via this connection was resumed on October 1, 1907 when Second Avenue locals were extended to Freeman Street during rush hours.[6]

On October 28, 1910, the new 180th Street station, known as Zoological Park station, opened as the new terminal of the West Farms Division of the subway, replacing the temporary station at 180th Street, which was later abandoned.[8]

The Dual Contracts, which were signed on March 19, 1913, were contracts for the construction, rehabilitation, and operation of rapid transit lines in the City of New York. The contracts were "dual" in that they were signed between the City and two separate private companies (the Interborough Rapid Transit Company and the Brooklyn Rapid Transit Company), all working together to make the construction of the Dual Contracts possible. The Dual Contracts promised the construction of several lines in the Bronx. As part of Contract 3, the IRT agreed to extend the existing West Farms Division from 179th Street to 241st Street as an elevated line along White Plains Road.[9][10][11]

Intervale Avenue station opened on April 30, 1910 as an in-fill station. It was the first station in the Bronx with escalators. The station was built at the cost of $100,000, and it was paid with private capital.[12][13]

Portions of the White Plains Road Line were opened at different times, and they opened once construction finished on a segment, as opposed to waiting for the completion of the entire line. The first segment opened on March 3, 1917, from East 177th Street–East Tremont Avenue to East 219th Street–White Plains Road, providing the Bronx communities of Williamsbridge and Wakefield with access to rapid transit service.[14][15] Service on the new portion of the line was operated as a four-car shuttle from 177th Street due to the power conditions at the time. Service was extended to East 238th Street on March 31, 1917.[14][16] The part of the line from the S-curve north of West Farms Square—East Tremont Avenue station to the terminal at 241st Street was built as a part of the Dual Contracts.[10]

On July 1, 1917, a new connection between the White Plains Road Line and the Third Avenue el express tracks opened as part of the Dual Contracts expansion of the Third Avenue Line, and since it ran via Bergen Avenue and bypassed the 149th Street station, it was called the Bergen Avenue cutoff or bypass.[14] The Bergen Avenue cutoff was abandoned on November 5, 1946, as part of the gradual curtailment of elevated service on the IRT Third Avenue Line.[6] The cutoff was removed in 1950.

On December 13, 1920, the final portion of the line opened, extending the line from its previous terminal at 238th Street to the line's permanent terminus at 241st Street.[17] This portion of the line had its opening delayed, owing to construction on the line between the two stations for the construction of the 239th Street Yard. Additional time was required to modify the structure to avoid a grade crossing at the entrance to the yard.[18]

A 1929 proposal included a spur off the line that would have run from Van Nest to Baychester. The spur was to begin near Garfield Street as an elevated line then run underground beneath Morris Park Avenue and Wilson Avenue, finally terminating at Boston Road, where it was to connect to the formerly proposed Concourse Line extension. This proposal was never carried out, however the IRT acquired the former New York, Westchester and Boston Railway right-of-way to create the IRT Dyre Avenue Line instead.

The New York State Transit Commission announced plans to extend the southbound platforms at seven stations on the line from Jackson Avenue to 177th Street to accommodate ten-car trains for $81,900 on August 8, 1934.[19]

On June 13, 1949, the platforms extensions at the stations on the line from Jackson Avenue to 177th Street opened. The platforms were lengthened to 514 feet (157 m) to allow full ten-car express trains to platform. Previously the stations could only platform six-car local trains.[20]

On March 1, 1951, the Board of Transportation announced a plan to implement express service along the White Plains Road Line between 241st Street and Third Avenue–149th Street using the middle third track. New signaling, including the installation of block signals, was to be installed on the local tracks, in addition to the installation of signals on the express track at the cost of $3.5 million. In addition, it was announced that a flyover to the Dyre Avenue Line would be built, allowing for through-service, and eliminating the need to transfer at East 180th Street. The final key element to the improvement plan was the elimination of the at-grade junction north of the West Farms Square station, which was a major bottleneck, by closing the spur to 180th Street–Bronx Park. To make up for the loss of service, an escalator and new stairway would be added at the West Farms Square station at 178th Street and Boston Road.[21] The spur to 180th Street—Bronx Park closed on August 4, 1952.[22]

Express service on the IRT White Plains Road Line began on April 23, 1953 with alternate 5 trains using the middle track between East 180th Street and 149th Street during the weekday rush in the peak direction. These trains skipped all stops between East 180th Street and Third Avenue–149th Street.[23] Starting on October 2, 1953, 5 trains began running express between East 180th Street and Gun Hill Road using the middle track in order to encourage passengers who changed at Gun Hill Road for Third Avenue Elevated service to stay on subway trains.[24][25][26] These trains were signed as the 5 Lexington Avenue Thru-Express.[27]

The Dyre Avenue Line was connected directly to the White Plains Road Line north of East 180th Street for $3 million and through service began on May 6, 1957. Night service continued to be operated by a shuttle.[28] Through service was operated by Seventh Avenue express trains between 5:30 AM and 8:30 PM. Between 8:30 and 1:15 shuttle trains operated from East 180th Street to Dyre Avenue, and in the early morning hours no trains operated over the line.[29]

Due to rehabilitation of East 180th Street and signal replacements along the line, rush hour peak direction 5 express service was suspended from March 29 to September 3, 2010. PM northbound express service was suspended again on March 28, 2011 to allow for the second phase of the signal replacement project. Normal service was restored on August 8, 2011.
