3. Myrtle Avenue Line
Today there is a Myrtle Ave line that runs through Brooklyn, but it is not the same one the past. What is used today follows the remnants of the old Myrtle Avenue Line which ran from Jay Street to Metropolitan Ave until it was abandoned on October 4, 1969. This particular line was the last one in the entire city to use the wooden cars typically operated on the elevated lines.
The Myrtle Ave Line opened in April 1888 running between Adams Street station in downtown Brooklyn and Grand Avenue in Clinton Hill. Through the next few years it would slowly branch out further until 1906 when it was finally extended to Metropolitan Ave. Today, the eastern most part of the line between Wyckoff and Metropolitan Avenues is still being used by the M subway line.
