Jamaica as RJ, along the route used today by the J and Z services. Under the first color scheme, RR was colored green and RJ was red. In the original Chrystie Street routing plans, the TA planned to totally eliminate the RR service, and maintain the RJ route as the main Bay Ridge service. The RJ designation was only used from November 1967 until July 1, 1968, when it was cut back to Chambers Street and renamed as additional RR rush-hour peak-direction service. Because track connections between the Nassau Street Loop and the south tracks of the Manhattan Bridge were severed as part of the construction of the Chrystie Street Connection, these trains could not run in a loop anymore. On August 30, 1976, the EE was discontinued, with the N being extended to Forest Hills on weekdays to replace it. On January 24, 1977, as part of a series of NYCTA service cuts to save $13 million, many subway lines began running shorter trains during middays. As part of the change, RR trains began running with six cars between 10:45 a.m. and 2:05 p.m. In 1979, the MTA released a revised coloring scheme; RR service was assigned the color yellow (because it used the BMT Broadway Line). Although BMT Nassau Street Line services were colored brown, the rush hour RR service that used the Nassau Street Line was colored yellow, using a diamond bullet. The RR service via Nassau Street was referred to as the "Chambers Street Special". 1980s-2000s changes On May 6, 1985, the MTA eliminated double letters for local service; the RR became the R. R service on the Broadway Line continued to use a yellow bullet, while the special Chambers Street–Bay Ridge rush-hour service was signed with a brown diamond with a white R inside, matching the J and M services using the BMT Nassau Street Line. Starting on April 28, 1986, R service on the Nassau Street Line was extended to Metropolitan Avenue for layups and put-ins from Fresh Pond Yard. After the N/R swap, the Nassau R used East New York Yard equipment. This rush hour service was discontinued on November 20, 1987. On May 24, 1987, the northern terminals of the N and R were swapped. The swap placed the R along the IND Queens Boulevard Line to Forest Hills–71st Avenue once again, with the N replacing it in Astoria. The change was
