Stumbled across a paper in the Austrian technical magazine Die Locomotive 1912 about the 0-6-2T loco Borsig 6022/1906, Hulleras de Sabero No. 7, now in the Rampton Trust collection: http://anno.onb.ac.at/cgi-content/anno-plus?aid=lok&datum=1912&page=140 and the following page. From the data and text it appears as this loco is truly remarkable. It is built as early as 1906 and has a high degree superheat! This is very early and probably one of the absolutely first superheat locos on 2 ft gauge. With a 7 ton axle load it is of about the same size as the 2-6-2T locos of VoR, but thanks to the superheat, larger boiler, much higher boiler pressure and smaller wheels it probably has substantially higher output power at the speeds used at the VoR. It is stated in the text that it was the most powerful 600 mm gauge loco in the world at the time it was built and a figure of 200-250 hp is given. Another odd feature is that I am not aware of any other engine on the same line as powerful as this one, must have been "a white elephant" sort of. Could we only dream of seeing it in action?
