Class Details by Steve Llanso of Sweat House Media

Class H / Hs (I) (Locobase 3969)

Data from WilliamBay, Danmarks Damplokomotiver (1977). Class info from [link].

These little four-coupled tanks were delivered sporadically for a decade and a half. They were based on a design originally supplied to the Ermstal-Bahn, which linked Bad Urach and Metzingen in Wurttemberg. In Denmark, they first operat

Esslingen delivered the first 7 of the class in 1873, 1876, 1880 (1 each year), 1883 (2), and 1884 (2). Hartmann supplied 2 more (SJS 62- SJS 63) in 1888, Esslingen added 3 in 1889, and Hartmann finished the class in 1893 with 3 more.

In 1893, the Danish State Railway (DSB) renumbered the class and redesignated them Hs (I). The class had careers of widely varying length. A couple were withdrawn before World War Two and a couple were lost during the war. The rest remained in service into the late 1950s. A


Class Ms (Locobase 3979)

Data from WilliamBay, Danmarks Damplokomotiver (1977). Production data from [link].

Scrapped in September 1932.
