a recreational vehicle derived from its bus body. By 1927, Wayne introduced the use of steel for its external body panels (combined with a wood internal frame). First buses In the 1910s, Wayne chose to become a body manufacturer for truck chassis (such as the Ford Model T). In 1914, alongside a line of commercial truck bodies, the company introduced its first motorized "School Car", its first school bus mounted on an automotive chassis. In the vehicle bodies for school transportation that the company produced during this era, passengers sat on perimeter seating, facing the sides rather than the front of the bus. In place of wooden benches, the 1914 School Car was fitted with padded seats. Entry and egress was through a door at the rear, a design first utilized from the days of wagons (to avoid startling the horses). This feature was retained, becoming the rear emergency exit seen on the buses of today; the primary mode of ingress/egress is now through a curbside door. Following World War I, Wayne Works began to produce the School Car in large numbers; alongside changes in education funding and school modernization, the motorized school bus was a contributing factor in the decline of rural one-room schools in United States. Although fewer children lived within walking distance of school, school systems consisted of fewer but larger multi-room schools. 1930s: Safety innovations The 1930s marked a number of significant changes in school bus design. Among other manufacturers, Wayne would introduce changes that have remained part of school bus design, even decades later. In 1930, Wayne Works became the first manufacturer to replace steel-sheathed bodies with full-steel construction, including the internal body frame. Initially offered as an option, the all-steel body became standard in 1933. In 1933, Wayne became the first manufacturer to offer an all-steel body with safety glass windows. In addition, the company began to phase in the heavy-duty reinforced side rails seen on school buses, "collision rails" or "guard rails" became an added safety feature. For 1936, Wayne redesigned its school bus body, making it sectional, allowing a customer to add or remove sections for repair or change capacity. In 1937, the company produced its largest school bus, seating 115 students. In 1938, Wayne Works introduced its first forward-control school bus, offered as a second-party conversion on its conventional-chassis body. In contrast to later front-engine buses, the driver sat on top
