Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 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. The diameter of the single piston valve feeding both cylinders on a side (one HP, one LP) measured an unusually precise 9 3/4" (247.65 mm). A key color detail in the paint scheme required a carefully drawn detail in the specs showing the top of the stack and the raised band just below the cap. "Paint this band red", it instructed.
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. The B&S used the compound on way-freight and log trains, rebuilding the engine in 1904 with two 19" x 24" simple-expansion cylinders.
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 Bellingham & 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 and only scrapped it in December 1929.
