Английская Википедия:Chicago and North Western D Class
Шаблон:CleanupШаблон:Infobox locomotive The Chicago and North Western Railway D Class was a class of 92 American 4-4-2 "Atlantic" locomotives. They were built by Schenectady Locomotive Works and by its corporate successor the American Locomotive Company between 1900 and 1908. In addition, the Chicago, St. Paul, Minneapolis and Omaha Railway (Omaha Road) bought seven, classifying them as class G-3
Design
The locomotives had a boiler pressurized to Шаблон:Convert providing steam to two cylinders with a Шаблон:Convert bore and a Шаблон:Convert stroke. They were connected to Шаблон:Convert driving wheels by a variety of valve gear: most had Stephenson valve gear and Шаблон:Convert piston valves; No. 1026 was fitted up with Youngs rotary valves and valve gear in 1903,Шаблон:Sfnb but later reverted to Stephensons valve gear. The 1908 batch had Walschaerts valve gear, the first five locomotives having piston valves and the last ten were delivered with Young rotary valves; these were replaced with piston valves when the locomotives were fitted with superheaters.Шаблон:Sfnb
Construction
All 92 locomotives were built by Schenectady Locomotive Works (SLW) and by the same works under its corporate successor, the American Locomotive Company (ALCO).
In September 1904, ALCO announced their introduction to steam locomotives with superheated boilers, following some successful test runs by a European locomotive at a St. Louis exhibition.[1] The C&NW subsequently asked ALCO to construct one D class 4-4-2 (No. 1300) and one R-1 class 4-6-0 (No. 76) with superheated boilers.[1][2] The railroad became unsatisfied with the performance of Nos. 1300 and 76, and no further D's or R-1's were built new with superheaters.[2]

Service
At the time of their introduction, wooden cars were the norm. The class D locomotives were quite capable of pulling a 10-car, 400-ton train on the 138-mile Chicago to Clinton route in 3 hours 25 minutes inclusive of eleven stops.[3]
Unfortunately, steel cars came into use soon after, and the locomotives became outclassed. They were then downgraded to commuter service and locals.
On the Omaha Road, one of the later uses of their class G-3 was powering the Minneapolis to Ashland train The Namakagon substituting for the regular gas-electric car when it was in the shops or the load exceeded its two-car capacity.Шаблон:Sfnb
Retirements started in 1931, and continued until the end of steam in 1956 when the last two were retired from Chicago commuter service.
