Avenue Elevated (the continuation of the Fulton Street Elevated). The Eighth Avenue–Canarsie route was given BMT marker 16, and trains running to Lefferts Boulevard usually were marked as 13. When the Fulton Street El was torn down, some rush-hour Broadway trains ran through from the Broadway Elevated (Jamaica Line) to Canarsie via the flyover at Broadway Junction; these were marked as 14. In 1967, when all BMT services were given letters, the 16, which used the full Canarsie Line, was designated as LL. The rush-hour Broadway service (14) was designated JJ. The JJ ran until 1968 when it was replaced by the KK which stayed on the Jamaica Line instead of switching to the Canarsie Line at Broadway Junction. The flyover connection has not been used by any regular revenue service since then. Skip-stop service proposal In 1991, skip-stop service was proposed in order to speed service during the height of rush hours in the peak direction which would have reduced the running time from 41 minutes to 37 minutes. Under this plan, the K designation, which was previously used as the Broadway Brooklyn Local from 1967 to 1976, and as the Eighth Avenue Local from 1985 to 1988, would be repurposed and would appear in a gray bullet similar to the color the L uses. Both services would have common stops at Rockaway Parkway, Broadway Junction (then called Eastern Parkway), Myrtle Avenue, Lorimer Street, First Avenue, Union Square, Sixth Avenue and Eighth Avenue. L trains would stop at East 105th Street, Livonia Avenue, Atlantic Avenue, Wilson Avenue, DeKalb Avenue, Morgan Avenue, Grand Street, and Bedford Avenue; K trains would stop at New Lots Avenue, Sutter Avenue, Bushwick Avenue–Aberdeen Street, Halsey Street, Jefferson Street, Montrose Avenue, Graham Avenue and Third Avenue. This change was proposed as a service improvement alongside other changes that would have either reduced or eliminated service in order to balance the MTA's operational budget, but was never implemented. Chaining information The entire line is chained BMT Q. This has no relation whatsoever to lettered train service that operates on the line, which is designated L. The tracks on the line are labeled Q1 towards Canarsie and Q2 towards Manhattan. Chaining zero is BMT Q, now located at the compass western end of the line at Eighth Avenue and 14th Street in Manhattan. The entire Canarsie Line is coextensive with chaining letter BMT Q and this chaining
