Kelly's Creek 2-8-2 "Mikado" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 12 (Locobase 15303)

Data from DeGolyer, Vol 73, pp.190. Works number was 57202 in September 1923.

Kanawha & Hocking Coal & Coke Company bought this locomotive for their not-to-be-confused-with-the-Kelley's Creek & Northwestern railroad. The KCRR ran for 6.3 miles Cedar Grove to Mammoth in West Virginia. It opened in 1916.

The relatively large slide-valve Mikado rolled on 80 to 85 lb/yard (40 to 42.5 kg/metre) rail laid on sleepers 24" (610 mm) apart. It scaled 2 and 3 1/2% grades and ran around 18 degree curves.

The 12 later worked for the Warner Collieries company.
