N was a line operated by the Los Angeles Railway from 1920 to 1950. It ran from Spring and 2nd Streets to 8th Street and Western Avenue, by way of Spring Street, 9th Street, Vermont Avenue, and 8th Street.
The Ninth Street Line was built by the Los Angeles Railway in 1895 and ran via Spring Street, 9th Street, and Park View to a junction with the Lincoln Heights Line at 10th and Hoover Streets. From there both routes ran along West 10th Street to a terminus at Vermont Avenue. Circa 1911, the Park View section was eliminated and the route was extended along 9th Street, Vermont, and 8th Street to a loop at Western Avenue. In 1920, the route name was changed to "N." In 1950, the route was removed, though the 8th Street section of the line continued to run as part of the re-routed S line.
