J. G. Brill Company
The first trolley bus line in Dayton was opened by the Dayton Street Railway company (DSR). The impetus for the decision to adopt trolley buses was a 1932 fire at the company's carbarn (maintenance and storage facility), which gutted the building and destroyed 16 streetcars and two gas buses. After studying trolley coach systems then operating in other small cities, DSR placed an order with the J. G. Brill Company for 12 trolley buses, and these inaugurated service on the city's first ETB line in April 1933. However, the Dayton Street Railway was only the first of several companies to operate trolley bus service in Dayton, some of which operated concurrently and shared overhead wires on some sections, mainly in downtown.
