proposed a connection between the Queens Boulevard Line and the 60th Street Tunnel in 1940. Fifteen years later, on December 1, 1955, a connection to the 60th Street Tunnel opened, allowing trains from the BMT Broadway Line to serve Queens Boulevard as an additional local from 71st−Continental. This connection was one of the most important links in the system, correcting the 1930s error of insufficient capacity for Queens–Manhattan traffic. Service was initially provided by QT Broadway−Brighton trains (predecessor to the train). This service would be replaced by trains in 1961, a new EE train in 1967, and trains in 1976. On August 27, 1977, GG service was cut back to Queens Plaza during late nights, and local service along Queens Boulevard was provided by the . Effective May 6, 1985, use of double letters to indicate local service was discontinued, so the GG was relabeled G. On April 20, 1981, Councilman Steven Orlow said the New York City Transit Authority agreed to put a contract to replace the lighting at six stations on the Queens Boulevard Line from 75th Avenue to 169th Street up for bidding in October, with work to be completed by early 1982. The existing lighting at the stations meant that platforms were very dimly lit, and made riders feel unsafe. Until 1986, 2 E trains and 2 F trains started at Continental Avenue in the morning rush hour with the intention to relieve congestion. These trains were eliminated because they resulted in a loading imbalance as these lightly-loaded trains would be followed by extremely crowded trains from 179th Street, which followed an 8-minute gap of E and F service from 179th Street. On May 24, 1987, and services swapped terminals in Queens to provide R trains direct access to the Jamaica Yard. As part of the reroute plan, F service along Queens Boulevard was discontinued during late nights (1 a.m. to 5 a.m.). Late night local service was replaced by the R, which ran as a Queens Boulevard Local at all times. F trains were cut back to 57th Street on the Sixth Avenue Line during late nights. In addition, Queens Plaza became the northern terminal for the G train on evenings, weekends and late nights. In 1986, the TA studied which two services should serve the line during late nights as ridership at this time did not justify three services. A public hearing was held
