total carrying capacity by 4,000 passengers. The lengthening project cost $400,000. On March 23, 1970, southbound E trains, during rush hours, began stopping at the lower level of the 42nd Street–Port Authority Bus Terminal station. On August 28, 1977, late night AA service was eliminated. The A began making local stops in Manhattan during late nights, when the AA was not running. On May 6, 1985, the IND practice of using double letters to indicate local service was discontinued. The AA was renamed the K and rush hour CC service was renamed C. This change was not officially reflected in schedules until May 24, 1987. On December 10, 1988, the K designation was discontinued and merged into the C, which now ran at all times except late nights. The C ran from Bedford Park Boulevard to Rockaway Park during rush hours, 145th Street to Euclid Avenue during middays, and from 145th Street to World Trade Center during evenings and weekends. The A now ran express in Brooklyn during middays, and the B was extended to 168th Street during middays and early evenings. On May 29, 1994, weekend C service between 7 a.m. and 11 p.m. was extended to 168th Street to allow A trains to run express. Beginning April 30, 1995, C service was extended to 168th Street during middays as construction on the Manhattan Bridge cut B service from Manhattan. On November 11, 1995, midday service was cut back to 145th Street after B service to 168th Street was restored. The change was made to reduce crowding on the C and to reduce passenger confusion about the C's route. The B and the C, which both ran local along Central Park West, switched northern terminals on March 1, 1998, ending the connection between the C and the Bronx. Instead of alternating between three different terminals depending on the time of day, all C service now terminated at 168th Street. A report for the Lower Manhattan Development Corporation looking at the Lower Manhattan Rail Link, an idea to connect Lower Manhattan with the Long Island Rail Road and JFK International Airport, presented several alternatives that would utilize the Cranberry Street Tunnel instead of building a new East River Tunnel. These alternatives would have required that C trains be rerouted through the Rutgers Street Tunnel. In the wake of the September 11, 2001 attacks, World Trade Center station was temporarily not
