Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, p. 254. Works numbers were 35472-35473 in November 1911.
These mixed-traffic Ten-wheelers were suitable for both freight and passenger operations and contributed the basis for the Consolidation that would be bought for the same railroad fifteen years later (Locobase 15364).
