Pearl & Leaf Rivers 4-6-0 "Ten-wheeler" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 8 (Locobase 11747)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 25, p. 128. Works number was 21220 in November 1902.

The P & LR didn't enjoy an independent existence for very long after they took delivery of this modestly scaled Ten-wheeler. In 1904, the P & LR had expanded enough to adopt a new name. As the Mississippi Central, the company made room on their motive power roster as their 111 and served the MC for another 26 years before its scrapping in January 1930.
