Data from "Norwegian State Railway Locomotives," The Locomotive Magazine, Vol V (January 1900), p.11
Like its 2-6-2 stablemates (10135), these tanks had long wheelbases for their size. The two designs were identical except for the longer boiler in the 2-6-2 and the taller drivers in the present locomotive. The latter feature raised the top speed from 25 to 34 mph (55 km/h).
And as with the 2-6-2s, Dubs and Company in Glasgow supplied the first pair from a Norwegian State Railways design. Norway's Thunes Mekaniske Vaersted added 1 more in 1902.
With the closing of the Setesdalbanen in 1962 and the establishment of a tourist railway, the Thunes-built #6 was preserved and still operated on the line almost 50 years later.
