Kushequa 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Theodore Roosevelt (Locobase 12679)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 22, p. 188. Works number was 22222 in May 1903.

One of many Pennsylvania short lines, the KRR ultimately connected Camp Halsey with Farmers Valley, which were 24 1/2 miles apart. It was not a well-founded line, apparently, as it was closed in 1906. At that point the engine went to work on the Mount Jewett, Kinzua & Ritterville, which crossed the abandoned KRR at Gaffney.

The TR was scrapped in 1930.
