Raritan River 4-6-0 "Ten-Wheeler" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 11743)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 18, p. 37. See also Lucius Beebe, Highball! A Pageant of Trains (1945), Chapter 1, which is reproduced on the Raritan River website http://www.raritanriver-rr.com/Highball.htm . . Works number was 12838 in July 1892.

At the time they took delivery of this small Ten-wheeler, the Raritan River covered 12 miles from South Amboy to New Brunswick, NJ. It ran from 1892 to 1938. During World War One, the heavy demands for workers at the various defense plants in the area resulted in the carriage of almost 2 1/4 million passengers in 1918.


Class 4 (Locobase 12333)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 22, p. 69. Works number was 16528 in February 1899.
