The port fell into decline following the seaway opening and the start of year-round icebreaker services in the 1960s. In 1994 CPR left Saint John when it sold the line to shortline operator New Brunswick Southern Railway. The Canadian National Railway still services Saint John with a secondary mainline from Moncton.
