Alco S4 LokSound and DCC Master(R) Gold Southern Pacific 1477 (black, orange)

Details:

Alco introduced the S-4 in 1950. The S-4, like the earlier S-2, was a 1000-horsepower switcher. Some 636 S-4’s were built for North American railroads. The primary quick spotting difference between the S-1/S-2 and the S-3/S-4 can be seen in the trucks. The S-1/S-2 has Blunt trucks, while the S-3/S-4 has AAR-style trucks. The versatility of the S-2’s and S-4’s was evidenced by their service in mainline railroads, shortlines,
and industrials.
