The Connecticut Valley Railroad opened for service in 1871, connecting towns along the Connecticut River between Hartford to Old Saybrook on the coast. This line carried passengers and freight between commercial and trade centers. The Deep River Station, which is sited along the banks of the Connecticut River, was built about 1915 by the New York, New Haven and Hartford Railroad, who had acquired the Connecticut Valley Line, as part of a government-mandated program to update aging railroad infrastructure. This station was originally built to serve both passengers and freight and showcases the dwindling usage of train service with the more vernacular and less ornate architecture compared to 19th century stations. Passenger service on the line was soon decimated by competition from the automobile, and ended in 1933. Freight service continued until 1961, when the New York, New Haven and Hartford Railroad went bankrupt. A portion of the former Connecticut Valley Railroad track was revived as a heritage railroad in 1971, connecting this station to the 1892 Essex Station via steam train!
