American Car and Foundry (ACF), a pioneer transportation manufacturer, came into existence in 1899 as a result of the merger of 13 railroad-manufacturing companies. After a complicated transaction in the mid-20s, ACF had control of the Brill Corporation, Hall-Scott Motor Company, and Fageol Motors Company. From the beginning, both intercity and transit buses were built by ACF. ACF began to capture large orders for intercity buses, especially when the National Trailways Bus System was formed. Sharp black & white photos with in-depth captions combine to capture this important part of bus history.
