Lehigh & Lackawanna 2-8-0 "Consolidation" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 26 (Locobase 12015)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 17, p. 184. works numbers were 12430 in January 1892; 12496, 12501 in February.

Almost as soon as the 26 was delivered, the L & L transformed into the Lehigh Coal & Navigation; 27-28 were ordered and delivered by the latter. They were orthodox Vauclain compounds with two 10 1/2" piston valves, one serving a HP-LP cylinder combination on each side of the smokebox. The combustion chamber contributed 30.5 sq ft to the direct heating surface area.

These do not appear to have been rebuilt as simple-expansion engines. In 1913, the LC & N reorganized as the Lehigh & New England and this trio was placed in the E-3 class and renumbered 51-53. They were scrapped in 1917.
