Tooele Valley 2-8-0 "Consolidation" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 11 (Locobase 12513)

Data from "Equipment and Supplies - Locomotive Building," Railway Age Gazette, Vol 48, #4 (28 January 1910), p 214. See Peter Roehm, "The Last Buffalo & Suquehanna Steamer", Railpace Newsmagazine, pp. 14-18, archived at http://wnyrails.org/files/Last%20B&S%20Locomotives.pdf. Works numbers were 47764- 47765 in April 1910.

In the same year that ten wide-firebox Consolidations were logged in Alco's order book for the Buffalo & Susquehanna as their 169-178, the line went into receivership.

Only the 169 and 170 were actually lettered and numbered for the B & S and they never actually operated in New York. Instead, the Anaconda Copper Mining Company bought both for its seven-mile short line in Utah. The TV last operated the 11 in 1962. The 11 was later put on display at Tooele, Utah
