Class Details by Steve Llanso of Sweat House Media

Class G (Locobase 11656)

Data from Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University Vol 14, p. 6. Works numbers were 8860 in October 1887; 8862-8863 in November.

These Moguls were used as switchers and trailed a slope-back tender as a result.


Class L (Locobase 11665)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 14, p. 96 and Volume 16, p. 196. Works numbers were

1888

January 9017, 9019-9020, 9022-9026, 9029-9030

1891

January 11535, 11537, 11544, 11551-11553; February 11640; June 11978, 11981, 11986, 11989.

The BR & P bought this class in 10- and 11-locomotive orders.

Much of the class was sold off in 1905-1906 with the rest being scrapped in 1901-1911. Most of those that were sold were bought by locomotive recycler Southern Iron & Equipment.

Even an old Mogul was a pretty handy locomotive, as the diversity of new owners of some of the Ls suggests. Illinois main line Alton & Southern took 83. 73-74 went West to Washington State's Spokane International, 76 joined the Birmingham & Northwestern as their 22, while 79 landed on Colorado's Roaring Fork Railroad. Still farther flung was 82, which sailed up to the Copper River & Northwestern, which ran 196 miles from Kennicott, Alaska to Cordova.

Finally, 93 to the far-north James Bay Railway, which was planned to head north from Toronto to James Bay, some 265 miles due north. This railway, which had struggled for years with this project, was reorganized in the same year (1905) as the Canadian Northern Ontario Railway (part of the Canadian Northern).
