Occasionally, a prototype is so heavily requested that BLI felt compelled to produce it, at least in part, out of sheer obligation to our faithful customers. The Milwaukee S-3 is one such prototype. Behind only the PRR H10s, the Milwaukee S-3 is our most requested steam locomotive and we are pleased to offer it to our enthusiastic Milwaukee modelers!
The S-3 is the culminating iteration of the Chicago, Milwaukee, St. Paul & Pacific Railroads own 1930 S-1 Northern design. In 1937, Baldwin delivered 30 S-2s into service and in 1940 delivered another 10 S-2 locomotives. Finally, in 1943, 10 S-3 locomotives -- road numbers 260 -269 -- were delivered to assist in the wartime effort, this time from the ALCO.
A slightly leaner version of its elder brother the S-2, the S-3 weighs in at 460,000lbs with a tractive effort of 62,040lbs.
