Class Details by Steve Llanso of Sweat House Media
Class 2 (Locobase 13265)
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 31, p. 180. See also the Shasta Cascade Rail Preservation Society description of the #2 at [
], last accessed 15 October 2011. Works numbers were 32651 in January 1908.
This low-drivered tank operated on the SV & E in a shuttle between the Espee Junction at Pitt, Calif and the mill until the railroad closed in 1942 to make way for the Shasta Dam.
