Atlas 40005332 - Montana Rail Link

Built by EMD between 1954 and 1959, the SD-9 6-axle road switchers produced 1,750 HP and were used primarily for freight service throughout the US, both on main and secondary lines. Many SD-9 locomotives are still in service today, serving as road switchers for shortline & industrial railroads, and as yard switchers for major "Class 1" lines.
