During the 1930s, Thomas Car Works would see several changes that would alter the company forever. Following the large order from Detroit, demand for streetcars began to decline sharply. In 1930, the company received its last order for streetcars, producing 4 for Mobile, Alabama. Subsequently, all production would transition away from rail to road-based vehicles. During 1931 and 1932, no vehicles were produced, shifting to repairs, streetcar renovations, and automotive refinishing. In 1933, the company produced its first trolley coach (an electric bus with a pair of trolley poles).
