Cyril "Pop" Haworth had three sons; two assumed control of the company as partners in 1943: Thoburn (T.S.) and Bryan (B.W.).[1] Cyril retired in 1952 but continued to drive buses.[2][3] By 1955, OBS was serving routes totaling 400 mi (640 km).[1] Thoburn ran the Visalia branch while Bryan ran the Bakersfield branch until he was bought out in the mid 1970s. Thoburn's son Michael has run the company from Visalia since 1985.[1] The headquarters was in Visalia with branches in Fresno and Bakersfield.
The name Orange Belt Stages came from the route along the foothills of the Sierra Nevada mountains, where lush groves of oranges are found.[1]
In May 1969 a bus carrying a group of Girl Scouts from Universal Studios back to Bakersfield crashed and killed 3 young girls and injured many more.[4]
The company owned Orange Belt Adventures, a travel agency offering tours and charters.
Orange Belt previously ran a route from Visalia to Las Vegas; the route was cancelled in 2017.[5]
