Data for this SHE quintet from Roland's Eisenbahnseite ([] ..., accessed 27 December 2006). Works numbers were 327-329, 534 in 1901 and 2389 (in 1916)
See Locobase 3792 for the NWE sisters of this design.
This entry serves the dual role of marking the five narrow-gauge Mallet tanks that operated in southern Germany as well as preserving the original configuration of this relatively large class of engines. (The NWE entry shows the class after that railway's upgrades.)
As for the SHE engines, the first three were named Wurmberg, Stoeberhai, and Achtermann. The 1901 locomotive was named Braun Lage and the supplemental engine delivered in 1916 was nameless.
They had all been withdrawn by 1927.
