Winifrede Coal Company 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 13601)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 14, p. 38 Works number was 8827 in October 1887.

The property that would be the Winifrede first extracted coal from its West Virginia deposits up Field Creek beginning in 1853 and using a gravity-assist method. Its first locomotive came from Baldwin in the same year; it was an 0-6-0 named Winifrede with 13 1/2" x 18" cylinders and rolling on 42" drivers. That road was abandoned in 1858.

Later it would build 12 miles of track, 6 1/2 of which were the main line connecting its mines to the Chesapeake & Ohio junction. Engine #3 was the first with a leading truck.

NB: Locobase estimates the firebox heating surface by comparing this engine to the FC de Sagrado Mogul shown in Locobase 11572. The two sets of firebox dimensions included width and length measurements that came within 1/2" in each axis and the front and rear depth figures were identical. As the tube diameter, count, and lengths are identical, Locobase added the calculated tube surface area to the given firebox area to arrive at the evaporative heating surface.

Class 4 (Locobase 13600)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 34, p. 257. Works number was 34724 in May 1910.

The specifications for this coal-hauling Mogul emphasized that the road "... has a no. [sic] of sharp curves and loco. will be required to do a great deal of shifting on side tracks. Co. has no turntable." 4 was the next Mogul to be bought from Baldwin for this coal road and the last. Winifrede would buy several small electric motors from the Philadelphia builder.
