Map emphasizes the various local electric railway lines of the past, on Long Island.
Also shown, as thin black lines, are lines of the Long Island Rail Road, technically a "steam" railroad, although most of their suburban lines actually use a third rail electrification. Except for the New York & North Shore Traction Co. and the Babylon Railroad, all local electric railways were actually controlled by the Long Island Rail Road, and some lines functioned as feeder lines to the Long Island Rail Road.
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 entirely within New York City, with competing bus service beginning in 1912. The competing bus route later became part of Green Bus Lines.
