Asbury Rapid Transit System
Asbury Rapid Transit (1935-1958) was a small, privately owned bus system that existed in Los Angeles prior to the ascendancy of public transit agencies in the late 1950s. This transit system was officially formed in 1939 out of the Original Stage Line (which had operated since 1913) and the Pasadena-Ocean Park Stage Line (which had operated since 1919).
