In 1975, when the ownership of Wayne Corporation shifted from Indian Head to Thyssen, Wayne was one of six major school bus body builders in the United States. Wayne apparently enjoyed some profitable years in the late 1970s, buoyed by sales of its Busette and Transette product lines. By 1980, the company was one of the "Big Six" school bus body manufacturing companies in the United States, competing with Blue Bird Body Company, Carpenter Body Works, Superior Coach Company, Thomas Built Buses, Inc., and Ward Body Works; the Big Six were joined by Crown Coach Corporation and Gillig Bros., manufacturers which traded primarily on the West Coast.
