After the turn of the last century, buses were an alternative to horse-drawn public transportation. Few people had cars and trains were the principal mode of transportation for long distances. The 'Sight Seeing Car' made its debut and was put into service at vacation destinations. By the 1920's wood bodies gave way to steel on the larger commercial vehicles. But wood remained popular for the most utilitarian personal vehicle --- the station wagon.
After World War 2, Robert Campbell's Mid-State Body Co. of Waterloo, New York, met a brief resurgence of demand for small wooden buses built on truck chassis. These vehicles were used by schools, manufacturers, and tourist attractions. Many were exported. In 1957 the company, the last manufacturer of wooden buses, was bankrupt.
