Interstate 2-8-0 "Consolidation" Locomotives in the USA

Class 1 (Locobase 6440)

Data from Interstate diagram published on [] (visited 26 Dec 2004) and Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 30, p. 131. See also the history presented on the hillbillysavants blog at[] . Works numbers were 29136 in September 1906 and 32469 in December 1907.

The IRR ran between Stonega and Norton, Va and between Norton and Glamorgan. An additional 18-mile branch line connected Norton with the Clinchfield.

These engines were later retrofitted with Southern valve gear.

Class 5 (Locobase 5430)

Data from a table in May 1916 RME; see also DeGolyer Vol 59, pp. 420+. Works numbers were 42693-42695 in December 1915 and 53097 in April 1920..

This westernVirginia shortline class served the 88-mile (142 km) road for decades from the time of their purchase. Interstate opened in 1896 to move coal from several mines to L & N's connection at Appalachia. Later links reached Norton (N & W) and the Miller Yard (Clinchfield). In 1960 it was acquired by the Southern Railway.

These Consolidations had relatively tall drivers for a mountain profile, extended a long stroke in cylinders fed by 14" (356 mm) piston valves,, and rode lightly (which resulted in a low factor of adhesion). A small boiler was partially compensated for by a decent amount of superheat, though the design clearly was conservative.
