The Trailways system was first formed in 1936 as an association of five separate companies working together, to benefit from nationwide name recognition, and to offer through ticketing and scheduling. Some companies were actually owned by major railroads. By the end of its second year, 40 companies had become part of the Trailways system. The largest company to emerge was Continental Trailways, which was a consolidation through various mergers. Continental Trailways had its beginnings in 1927 as the Bowen Motor Coach Co., operating in Texas, which in 1945 was merged into Continental Bus System. Continental Bus System was one of the original companies merged into Transcontinental Bus System upon its formation in 1947. Transcontinental Bus System was acquired in 1968 by Holiday Inn, and sold by Holiday Inn in 1979. In 1987, Continental Trailways was acquired by Greyhound. While the various smaller Trailways companies continued to be separately owned.
