Pittsburgh, McKeesport & Yo NYC) 4-6-0 "Ten-Wheeler" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class F-103 (Locobase 15803)

Data from P&LE 1 - 1908 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 45962-45966 in May 1909.

Built two years before the F-104 and F-105 superheated Ten-wheelers delivered to the Pittsburgh & Lake Erie (Locobase 7071), the F-103s had saturated boilers. They were soon superheated to the same specs as the F-104 and F-105.
