This 1884 timetable documents Naugatuck Railroad service between Bridgeport and Winsted, about twenty years before control was assumed by the New Haven. Notice that both freight and passenger trains are shown in the schedule, as well as the "Watertown Division," showing service between Watertown and Waterbury.
Today's Naugatuck Railroad operates from just north of Waterbury Station to the current end of the line in Torrington. Frequent commuter service is offered between Waterbury and Bridgeport by
MTA Metro-North Railroad.
