Northern Wisconsin / Omaha & Northern Nebraska / Sioux City & St Paul / West Wisconsin 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 2/D-13 (Locobase 9321)

Data from CStPM&O 4 - 1900 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 9, p.201. Works number was 4824 in October 1879.

Surprisingly small Ten-wheeler for a branch of the St Paul & Sioux City that was originally built to forestall the construction of the Southern Minnesota line then planned for the same area. The little 4-6-0 may have been ordered by the Worthington & Sioux Falls as the #1, but the spec sheet in the DeGolyerRaildata collection shows that it was delivered to the O&NN.

In its career, the 2 was lettered for the Worthington & Dakota (1876), the Omaha & Northwestern (#2), St Paul & Sioux City (#50), and ultimately by the successor Chicago, Saint Paul, Minneapolis & Omaha (250).


Class C-2 (Locobase 9300)

Data from CStPM&O 4 - 1900 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 6, pages 149 and 228. Works numbers were 3142-3143, 3162, and 3166 in March 1873.

At the same time Baldwin delivered 63"" mixed-traffic Eight-wheelers (Locobase 9301) locomotives to the WW, the builder supplied this quartet of freight engines that duplicated the order except for the smaller drivers.


Class C-8 (Locobase 9304)

Data from CStPM&O 4 - 1900 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 10, p. 103. Works numbers were 5191-5192, 5216-5217, 5240-5242

Still on the small side, these Eight-wheelers had typical power dimensions for the time; they were delivered with 144 tubes. Their driver size equated to freight hauling.

Taken into the Omaha Road when the StP & SC taken over, most engines in this class were scrapped at the end of the first decade of the 20th Century.


Class Cumberland/C-1 (Locobase 9299)

Data from CStPM&O 4 - 1900 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Delivered to the NW from Pittsburgh as the latter's works #387. Ultimately this small Ten-wheeler was rebuilt as an 0-6-0 switcher.
