Indiana, Illinois & Iowa 4-6-0 "Ten-wheeler" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class I-5 / F-40 (Locobase 12585)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 24, p. 142. Works numbers were 19916-19919 in December 1901; 20110-20112 in February 1902; 20231 in March; and 20259-20260.

Not surprisingly, this 151.8-mile line was nicknamed the "3I Route". It also was known as the Kankakee [river] Belt Line. It was built from Streator, Ill to North Judson, Ill in the 1881. It was later extended to South Bend, Ind.

In 1906, the Chicago, Indiana & Southern Railroad Company was incorporated under the laws of Indiana and Illinois on April 9, 1906, as a consolidation of the Indiana, Illinois & Iowa Railroad, the Indiana Harbor Railroad and the Danville & Indiana Harbor Railroad Companies.

In November 1923, the 5282, 5287, and 5289-5290 were sold to the Saint Louis & Hannibal Railway.
