The Danbury and Bethel Traction Company was a company, originally mostly operating streetcars, but soon converting entirely to a bus operator, in Danbury and Bethel, Connecticut. It was the successor to the Danbury and Bethel Street Railway, organized in 1925.
Shortly after the reorganization of the D&BStRy as the D&BTCo, J. Moss Ives, who controlled the company, proposed to put buses on all routes as replacement for the trolley lines in 1926 as a cost saving measure. This led to a strike by the trolley motormen on November 22, 1926. The strike did not save the streetcars, and by the end of December, 1926, the trolleys had ceased operation with buses taking their place. The Danbury/Bethel area was the first trolley system in Connecticut to be dreplaced completely by buses.
Eventually, the D&BTCo was replaced by the Danbury Power & Transportation Company.
