Map emphasizes lines outside New York City, in Nassau and Suffolk Counties. Although the New York & North Shore Traction Co. had some lines serving Queens, New York, whose replacement bus service was eventually operated by the New York City Transit Authority.
The Ocean Electric Railway operated in the "Rockaway" suburbs, which were annexed to New York City in 1898. Competing bus service was introduced in 1912 by Long Island Coach Co., which later became part of Green Bus Lines.
