Wisconsin Central / Wisconsin & Northern / Minneapolis, St Paul & Sault Ste Marie / Minneapolis, Sault Ste Marie & Atlantic 2-6-0 "Mogul" Type Locomotives

Class 108 / D-20 (Locobase 8775)

Data from Soo 9 - 1943 Steam Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This relatively numerous class of Moguls went to the WC in 1887 as the railroad consolidated itself in the Nemesha-based line that would later become part of the Soo. Baldwin's works # ran 8700-8702, 8705-8708, 8712-8715, 8718, 8720, 8722 in August 1887 and 8824-25, 8829, 8831-32, 8835-8837, 8843 in October 1887.

Four were sold to Wisconsin companies in the 1920s: Consolidated Water, Power & Paper Company (2106, ex-114); Fountain Campbell Lumber Company (2110, ex-118); Stack Lumber Company (2114, ex-122); and Manistique Lime & Stone Company (2119, ex-127).

Class 6 / D-3 (Locobase 8774)

Data from Soo 9 - 1943 Steam Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Well, Ron Kohlin doesn't know where this single Mogul came from and his source, Leslie Suprey's Steam Trains of the Soo, apparently couldn't tell us. Locobase can say that the W & N began construction in 1907 as a lumber line and eventually connected Argonne in the north to Appleton further south. Its junction points with the Soo lay at Argonne and Neenah. In 1921, the Soo took it over.

Class D (Locobase 8772)

Data from Soo 9 - 1943 Steam Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

These Moguls were produced in two batches, which accounts for the break in builder's numbers: 1878-1881 and 2001-2004.

Class D-1 (Locobase 1326)

Data from Soo 9 - 1943 Steam Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.

Works #1214-1218 (April 1887), 1275-1279 (October 1887).

1349-1358 (March 1888) appear to be from the same class, but they're described as having gone to the Minneapolis, St. Paul & Sault Ste Marie (Soo Line) in 1892.

Bigger Moguls than the Baldwin Ds with larger cylinders, higher BP, and taller drivers. Original number series ran from 69 through the mid-80s, non-consecutively. Sold for scrap beginning in 1925 and ending in 1933.

Class D-2-S (Locobase 8764)

Data from Soo 9 - 1943 Steam Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This large class was originally delivered as a cross-compound, saturated-boiler design; the HP cylinder measured 21" and the LP 32". 65 locomotives arrived from Schenectady from 1903 to 1907.

Locobase's date for the superheater installation is an estimate. All were dismantled in the 1920s and 1930s. The diagram in the Soo book shows the first to go was 160 in August 1926, the last was 155 in November 1935.
