Amsterdam Avenues Line, and Broadway and Columbus Avenue Line. In 1919, the Ninth Avenue Railroad was separated from the bankrupt New York Railways, which had replaced the Metropolitan, and the Ninth Avenue and Amsterdam Avenue tracks were again linked by a single line, only shared with New York Railways cars (of the Broadway and Columbus Avenue Line) between 53rd Street and Broadway. The Ninth Avenue Railroad merged with the also-separated Eighth Avenue Railroad in December 1926 to form the Eighth and Ninth Avenues Railway. Bus service Buses were substituted for streetcars by the Eighth Avenue Coach Corporation, a New York Railways subsidiary, on November 12, 1935, and assigned the number M42. It was subsequently labeled 11 by the New York City Omnibus Corporation when it gained control in 1936. When Ninth and Tenth Avenues became one-way streets on November 6, 1948, traffic was split between 14th Street and 110th Street, with southbound traffic moving to Tenth Avenue south of Broadway, and northbound traffic moving to Columbus Avenue north of Broadway. The New York City Omnibus Corporation directly took over operations in 1951, and in 1956 it was renamed Fifth Avenue Coach Lines; the Manhattan and Bronx Surface Transit Operating Authority, now a wholly owned subsidiary of the MTA's New York City Transit Authority, replaced it in 1962. In its first 30 years in bus service, the 11's northern terminus was at La Salle Street and Broadway. On June 20, 1965, it was extended to 132nd Street and Broadway. On June 26, 1994, the route was extended along 135th Street and Riverside Drive to Riverbank State Park during park hours–7 a.m. to 11 p.m. During other times, the route terminated at its previous terminal at 132nd Street and Broadway. This extension added service along Riverside Drive between West 135th Street and West 145th Street, and provided access to the park from the south. The M11's previous terminal required a U-turn on Broadway, and the extension removed the safety hazard. After six-months, ridership on the extension was lower than expected, and the route extension was to be reevaluated after summer 1995.
