Class 3 (Locobase 14339)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 53, pp. 320. See also a brief account of the TVRR at http://freepages.genealogy.rootsweb.ancestry.com/~milliken/jottings/tvrr.html . Works number was 43570 in June 1916.

Like the 2 shown in Locobase 14340, this narrow-gauge Eight-wheeler remained with the TVRR throughout its career and was scrapped once this Pennsylvania road closed in 1934.
