Class Details by Steve Llanso of Sweat House Media

Class 9 (Locobase 21065)

Data from "2/3 gek. Guterzug-Locomotive fur normal Spurweite-Konigliche Militareisenbahn und Pruessis Staatsbahnen", (Tegel bei Berlin, 1878), p. 30. Works numbers were 4355 in March 1892.

The Kaiserliche und Königliche Eisenbahn-Bau Kompanie unit (German Imperial Railway Construction Company) used engines like this to support reconstruction of damaged right of way. It operated in the East during World War I.
