AB Hitchcock, logger 0-6-0 Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Harry (Locobase 3931)

Data from Railroad Gazette (16 March 1900). Works number was 2939 in 1900.

In the same Railroad Gazette article that described the new class of G-6 Consolidations being delivered to the Chesapeake & Ohio, this little logger's saddle-tank tea kettle also was described. It was illustrated standing on the same track as the 2-8-0, which weighed 6 times as much, RG noted. Although it seems unlikely that so small an engine would run on standard gauge, the picture suggests that this was so.
