These 4-6-6-4s were designated Class Z-6 and were assigned road numbers 5100 through 5120. They had four 23 x 32 cylinders, 69 drivers, a 250 psi boiler pressure, exerted 104,500 lbs of tractive effort and weighed 624,500 pounds. In 1941, another six Challengers came from ALCO.
These were designated Class Z-7 and they carried road numbers 5121 through 5126. They had four 23 x 32 cylinders, 70 drivers, a 260 psi boiler pressure, exerted 107,000 lbs of tractive effort and weighed 644,000 pounds.
This group designated Class Z-8 was assigned road numbers 5130 through 5149. The Class Z-8 locomotives were virtually identical those of Class Z-7. Two oil-burning Z-8s were also delivered to the SP&S. This class was essentially identical to the 1941 Z-7s these locomotives were produced under a wartime mandate to replace certain high-strength steel components with similar items produced with more common and heavier steel. Even so, the NPs diagrams show no difference in the adhesion weight and just a 1,000 lb difference on engine weight.
The firebox heating surface included 136 sq ft in eight circulators. These also featured a bearing design that permitted smooth riding at higher speeds.
