Ogden City 0-4-2 Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 10 (Locobase 11610)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 15, p. 61. See also Utah Rails, [], last accessed 14 August 2010; and see Locobase 16366 for a skeptical 1877 view of steam dummies and Locobase 11577 for a supporting 1889 discussion of the problems associated with running steam dummies on urban street railways.. Works numbers were 9955 in April 1889; 10442 in November 1889; 10950-10951 in June 1890; and 11336-11337 in November.

Ogden was among the many cities of every size that adopted steam power for its street railways and Baldwin had an appropriately sized engine for the city's requirement. Utah Rails notes that in addition to the steam dummies shown in this entry, the OCR bought a Shay locomotive. UR noted that its "...geared drive train ...allowed it to travel over uneven streets and turn the sharp corners found on typical street railways."

The whole enterprise was bankrupt by late 1890 and the Ogden Electric Railway took it over, to be followed almost immediately (19 May 1900) by its rescuer, the Ogden Rapid Transit Company.

All of the dummies found other homes. 10 went to work with the Union Railway company, 100 served the Imperial Manufacturing and Importing Company. The last three went to other street railways: 101 to the Salt Lake & Ogden (3 1/2 miles long with 40-lb/yard raile), the 6 to Provo Street Railway, and the 8 to the Great Salt Lake & Hot Springs.
