The trains of the South Devon Railway finally reached the town of Plymouth on 2 April 1849. Docks were opened adjacent to the station and a new headquarters office was built next door. The station was expanded ready for the opening of the Cornwall Railway on 4 May 1859 and the South Devon and Tavistock Railway on 22 June 1859. It became known as "Plymouth Millbay" after other stations were opened in the town in 1876-7 at Mutley and North Road.
