West Wisconsin / Saint Paul & Sioux City / Worthington & Sioux Falls / Northern Wisconsin 4-6-0 "Ten-Wheeler" Type Locomotives

Class C-2 (Locobase 9300)

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

These small Ten-wheelers (works #2677, 2680) were soon sold to the Chicago, St Paul, Minneapolis & Omaha in March 1878. The WW itself was merged with the Omaha Road in 1880.

Class C-8 (Locobase 9304)

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

Still on the small side, these Eight-wheelers (works #519-5192, 5216-5217, 5240-5242) had typical power dimensions for the time. 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 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.

Class D-13 (Locobase 9321)

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

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 was owned by the W & SF, the Worthington & Dakota (1876), the Omaha & Northwestern (#2), St Paul & Sioux City (#50), and ultimately by the successor Chicago, Saint Paul, Minneapolis & Omaha (250).
