Product Information

Power up your HO freight operations with Walthers Proto SD9 diesels!
The debut of the SD9 in 1954 marked the next step forward for EMD's Special Duty line of six-axle diesels, and introduced the new 567C prime mover delivering 1,750 horsepower. Ideal for demanding assignments in helper, yard, transfer and heavy freight service, with its weight spread over six axles, the SD9 was also well suited to branch line duties. By the time production ended in 1959, 515 SD9s were in service on over a dozen railroads and some are still going strong after 50+ years of service!
From superb paint and lettering to railroad-specific details, WalthersProto SD9 locos come ready for service and feature:

  • Easy multiple-unit operation
  • Superb paint & lettering
