Toledo, Peoria & Western 4-6-0 "Ten-Wheeler" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class G-4-A (Locobase 11509)

Data from Baldwin Locomotive Works Specification for Engines, 1903, as digitized by the DeGolyer Library of Southern Methodist University Vol 26, p. 223. Works numbers were 23587, 23598, 23613, 23622, 23636 in January 1904; 26637, 26650-26652, 26688 in October 1905.

Very like the RF & P locomotives shown in of the same year and builder (Locobase 7117), this class represented the lighter end of Ten-wheeler designs being procured in that period. Never superheated, these engines ran about 25 years before being scrapped in 1926-1929.
