Waterbury Trolleys traces the growth and expansion of the streetcar system throughout the Naugatuck Valley. This system became part of the Connecticut Company's extensive streetcar network, spanning 1,138 miles statewide at its peak in 1918. As automobiles became a primary mode of transportation, the streetcar lines in Waterbury transitioned to bus routes. By 1937, streetcars were officially replaced by buses. This wonderful collection of vintage photographs documents the network of streetcars that once thrived in Waterbury.
