Alexander & Rich Mountain 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Charles Lockhart (Locobase 11987)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 17, p. 64 . Works number was 11996 in June 1891.

The Charles Lockhart started on the A & RM, where the rail weighed 35-lb/yard. By that time the line had 15 miles of road.

The 1 wound up on several logging roads beginning with Wilson & Wood, moving on to Albemarle Timber Company, then to Tunis Lumber. Nothing is known of its post-1913 activities.
