In the mid-1960s, AC Transit in California pioneered the American use of a modern articulated bus, operating the experimental commuter coach "XMC 77" (based on Continental Trailways' Bus & Car Co. Super Golden Eagle model) on some of its transbay lines.[4][5] The XMC-77, which AC Transit dubbed the "Freeway Train", was originally built in 1958, purchased by the District in October 1965, and made its debut run for Line N on March 14, 1966;[6] passengers on the inaugural run were presented with special souvenir tickets. XMC-77 was later exhibited to the public at various locations in the East Bay and the Transbay Terminal.
