East Hannover 2-10-2 Locomotives in Germany

Class Details by Steve Llanso of Sweat House Media

Class 84 (Locobase 2462)

Data from H. Le Fleming in Ransome-Wallis (1959).

Krauss-Helmholz truck on this relatively small freight tank engine as on most German engines. Tonnage ratings for this engine were 500 tons at 50 mph on level track and 25 mph for the same tonnage on a 1% grade. Although the design has the 84-series numbering, it was in fact used in an industrial setting.
