Class Details by Steve Llanso of Sweat House Media

Class XIII / 155 (Locobase 4604)

Data from [link], accessed 16 August 2006.

The Wikipedia author says these locomotives replaced the SNDVB's Class IVa engines and differed chiefly from the Class XI in having a higher boiler pressure. The profile has the usual low-set cylinders mounted outside, stack with basket-shaped spark arrestor at the top, cylindrical dome over the first axle, and sand dome over the second. More unusually, the locomotive crew enjoyed accommodations in a cab suitable for a North American railroad.

Apparently quite satisfactory (and the specs suggest a good design if a trifle short in direct heating surface), the entire class survived World War One to be divvied up among the successors to the Austro-Hungarian Empire. Czechoslovakia received 7 as their clas 314.1, Yugoslavia adopted 5 as class 127. Poland's 5 were retired without even being redesignated. Italy received 1 as a war reparation which became FS 224.001. The CSD engines lasted the longest with the last being retired in 1950.
