Pittsburgh, McKeesport & Youghiogeny 4-4-0 "American" Locomotives in the USA
Class Details by Steve Llanso of Sweat House Media
Class 296/C-101 (Locobase 4977)
Data from 1929 SAL locomotive diagrams published on [
] . Works numbers were 4-8.
Locobase credits the PMcK&Y with this class after a great deal of surfing through the mounds of invaluable information supplied to Locobase over the years by Allen Stanley from his Rail Data Exchange collection.
Branch-line American absorbed by the Seaboard Air Line when it acquired the GF&A. Still in service in 1929.
