Recent rehabilitation projects include right-of-way repair and trestle replacement along Lake Kapowsin and between Mineral and Morton. The Mountain Division now has service to the Morton area. The Mountain Division interconnects and interchanges with the two transcontinental railroads, the Union Pacific Railroad and the Burlington Northern and Santa Fe Railway, in Tacoma at the north end of the line and at Centralia/Chehalis in the south. The Mountain Division also is connected for interchange with the Puget Sound and Pacific Railroad that serves west to Elma, Bangor, Bremerton, Shelton, Aberdeen and Hoquiam.
