The IRT Pelham Line is a rapid transit line on the New York City Subway, operated as part of the A Division and served by the 6 and <6> trains. It was built as part of the Dual Contracts expansion and opened between 1918 and 1920. It is both elevated and underground with Whitlock Avenue being the southernmost elevated station. It has three tracks from the beginning to just south of the Pelham Bay Park terminal. The Pelham Line also has a connection to Westchester Yard, where 6 trains are stored, just north of Westchester Square–East Tremont Avenue. As of 2013, it has a daily ridership of 205,590. History Planning On March 1, 1905, the Board of Rapid Transit Commissioners laid out its tentative plans for new subway routes to expand the city's first subway, which had opened on October 27, 1904. A preliminary report was released on March 9, and the final report was completed on March 30, before two further amendments were made on April 13 and May 12, 1905. On June 1, 1905, the Board adopted resolutions laying out multiple routes across the city, including Route 19, a line along Southern Boulevard and Westchester Avenue. The route was planned to begin at 138th Street and Third Avenue, with connections either with new subway lines to Manhattan, or to Route 17, a planned subway under Gerard Avenue. The three-track line would have then continued east under 138th Street to Southern Boulevard. It would then emerge as an elevated structure and continue via Southern Boulevard and Westchester Avenue to the "former village of Westchester." It was decided to have a portion of the line be constructed on an elevated structure due to the higher cost of building subways in the Bronx, whose soil was irregular and rocky. On July 14, 1905, the New York City Board of Estimate adopted resolutions approving the routes planned by the Rapid Transit Board, including for this route. On March 19, 1913, New York City, the Brooklyn Rapid Transit Company, and the Interborough Rapid Transit Company (IRT) reached an agreement, known as the Dual Contracts, to drastically expand subway service across New York City. As part of Contract 3 of the agreement, between New York City and the IRT, the original subway opened by the IRT in 1904 to City Hall, was to be extended north from Grand Central along Lexington Avenue into the
