The Millis Branch was a branch of what is now the MBTA Commuter Rail system. Branching off the still-operating Needham Line at Needham Junction, it ran through the towns of Dover, Medfield, Millis, and Medway. Due to lack of subsidies and poor ridership, the line was cut back to Millis station in April 1966, and all service ended on April 21, 1967.
