Manhattan; the colors of the tiles changed at each express station. Early operation The majority of the Eighth Avenue Line, from Chambers Street north to 207th Street, was opened to the public just after midnight on September 10, 1932, after three days of operation on a normal schedule but without passengers. The Cranberry Street Tunnel, extending the express tracks east under Fulton Street to Jay Street–Borough Hall in Brooklyn, was opened for the morning rush hour on February 1, 1933, with the exception of the station at High Street, which opened on June 24, 1933. Initially, only the Fulton Street entrance was open; the Adams Street entrance would open later once its escalators were completed. The Jay–Smith–Ninth Street Line opened on March 20, 1933, extending the line beyond Jay Street–Borough Hall. When the subway opened in 1932, express (A) and local (AA) trains served the line; expresses did not run during late nights or Sundays. Expresses and late night/Sunday locals were sent south into Brooklyn on February 1, 1933, and, when the IND Concourse Line opened on July 1, 1933, the C was added to the express service, while all locals became CC trains to the Concourse Line, forcing A trains to run local north of 145th Street. The E was added to the local tracks south of 50th Street on August 19, 1933, when the IND Queens Boulevard Line opened. The final major change came on December 15, 1940, when the IND Sixth Avenue Line opened. The AA was brought back as a non-rush hour local service, becoming the BB and switching to the Sixth Avenue Line at 59th Street–Columbus Circle during rush hours. The CC was kept only during rush hours to provide local service south past 59th Street. Additionally the C became a rush hour-only service, replaced by a full-time D over the express tracks between the Concourse and Sixth Avenue Lines. This created the pattern that has remained to this day, with five services during normal hours: the A express, B part-time local via Sixth Avenue (then BB), C local (then AA and CC), D express via Sixth Avenue, and E local from Queens. Later years In 1953, the platforms were lengthened at Spring Street and Canal Street to to allow E trains to run eleven-car trains. The E began running eleven-car trains during rush hours on September 8, 1953. The extra train car increased the
