Seeing war-time power demands increasing, from 1940 to 1944, the Northern Pacific took delivery of 28 4-6-6-4 "Challengers". These were delivered from ALCO in two virtually identical classes: Z-7 (#5121-5126) and Z-8 (#5130-5149). All were accompanied by "centipede"-type (4-10-0) tenders with a capacity of 25,000-gallons of water and 27-tons of coal, which permitted up to 2 hours and ten minutes of steaming before taking on more water!
While the Union Pacific Challengers are more widely know, the NP Challengers were serious work horses, capable of tugging 100+ freight cars or 30+ coaches at 50+ m.p.h. This was done in the NP's mountain divisions on low-quality coal! Little wonder that these powerful locomotives lasted though the end of steam. All were scrapped by 1959.
The SP&S wisely copied the Z-8 design for their #910 and #911, though modified for oil-firing. The Division Point and Boo-Rim will offer this LIMITED EDITION project in different numbers of both classes. The SP&S versions will also be offered. As is usual, lighting is included and these will be DCC-ready. With a limited number of pieces to be produced, you are well advised to contact your dealer to reserve yours! (December 10: road numbers have been selected on the basis of photo evidence. See below!
This is our ANNIVERSARY Special Edition model with a special presentation box and a certificate signed by the builder! Due in the Spring of 2008.
| As usual, we are indebted to those folks who publish the information and photos we need. We urge you to buy their books and photos. |
