Page "Bus" Paragraph 20

Early bus manufacturing grew out of carriage coachbuilding, and later out of automobile or truck manufacturers.

Early buses were merely a bus body fitted to a truck chassis.

This body + chassis approach has continued with modern specialist manufacturers, although there also exist integral designs such as the Leyland National where the two are practically inseparable.

Specialist builders also exist and concentrate on building buses for special uses, or modifying standard buses into specialised products.
