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.
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).
These Moguls were produced in two batches, which accounts for the break in builder's numbers: 1878-1881 and 2001-2004.
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.
This was a large class of cross-compound Moguls of relatively generous proportions. The HP cylinder was supplied by a 12" piston valve while the LP cylinder used an Allan-Richardson slide valve.
See Railway Master Mechanic,October 1905, pp. 347-348 for a detailed description of the one of this class delivered with a Schmidt superheater.
They were later superheated by the Soo and given outside Walschaert gear; see Locobase 8764.
This large class was originally delivered as a cross-compound, saturated-boiler design; see Locobase 11170, except for one that was delivered with a superheater in 1905. The class apparently continued as cross-compounds until they were superheated, at which time the shops replaced 123 of the small tubes with the 21 superheater flues. They also installed outside Walschaert valve gear. Engine weight grew by about 3 tons.
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.
