Altoona & Phillipsburg Connecting 2-8-0 "Consolidation" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 12082)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p. 31. Works number was 13800 in October 1893..

At the same time the A & PC bought the Eight-wheeler described in Locobase 12082, it procured another medium-sized Vauclain compound. Apparently, compound Consolidations were fine as they were because the A & PC didn't rebuild this as a simple-expansion engine. Nor did the Buffalo & Susquehanna when it took it over as 101 in 1899.

After a stint with locomotive rebuilder/reseller Hicks Car & Locomotive Works, the 101 went west to the Bellingham Bay & British Columbia and was given road number 6. The railroad was renamed the Ballingham & Northern in 1912, then taken over by the Chicago, Milwaukee, St Paul & Pacific in 1914. The Milwaukee Road renumbered it 7563 in 1920, reclassified it C9-c (for compound) and only scrapped it in December 1929.
