Cincinnati, Flemingsburg & Southeastern 4-6-0 "Ten-wheeler" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 9 (Locobase 14108)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 47, p. 252. See also . Works number was 40009 in June 1913.

Several grand plans and false starts afflicted this Kentucky line over its troubled history. The road that would become the CF&SE emerged from reorganization in 1891 as the narrow-gauge Covington, Flemingsburg & Ashland. Another reorganization in 1905 resulted in the CF&SE. After a bridge collapse on the 11-mile Hillsboro-Flemingsburg section killed 3 passengers and injured 20 in 1907, the railroad abandoned all but 6 miles between Flemingsburg and Flemingsburg Junction (with the L&N), Ky and widened that track to standard gauge in 1909. Rail weight was 58.25 lb/yard (29 kg/metre).

Four years later, the CF&SE ordered the small Ten-wheeler that was given the number 9. The 9 operated on the 6-mile line for the CF&SE and its 1920 successor Flemingsbug & Northern until it was scrapped in 1937.
