Lokalbahn B~hmisch Leipa-Steinsch~nau 0-6-2 Locomotives in Austria


Class Details by Steve Llanso of Sweat House Media

Class VIb / 265 (Locobase 4641)

Data from [], accessed 13 August 2006.

These two radial tanks operated on the BLS localbahn for their entire working lives. After World War One, ownership passed to the CSD, which reclassified them as 312.7 and when the DRG controlled them in World War II, they were classed BR 90.3.

Whatever their designation, they apparently were satisfactory and ran until 1949.
