Class Details by Steve Llanso of Sweat House Media

Class H (I) (Locobase 4028)

Data from WilliamBay, Danmarks Damplokomotiver (1977). Works numbers were Borsig 11599-11600 in 1923 (road numbers 799-800) and 57-66 in 1926 (road numbers 789-798).


Class H (II) (Locobase 2473)

Some data from

[]. Works numbers were 305-310 in 1941.

Described by H. le Fleming (in Ransome-Wallis, 1959) as "fine examples of the medium European freight engine." Tonnage rating was 900 tons on a 1% grade. Driver spacing was uneven, showing a big gap between the first and second and an even larger gap between the third and fourth. This long-wheelbase layout probably contributed to its reputation as being "remarkably free from slipping." Their ability to handle tight curves came from the use of a Krauss-Helmholz truck that combines the first driving axle with the pony truck.

Every engine in the class operated on the DSB until the end of steam in 1967.
