Class 2 (Locobase 11854)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 13, p. 111. Works number was 8119 in September 1886.

See Locobase 11663 for a history of the S S & S, a common-carrier and logging road in southeastern Virginia. This high-drivered Eight-wheeler (it's all relative) was the second locomotive on the line.
