Austrian Southern 4-4-0 Locomotives in Austria
Class Details by Steve Llanso of Sweat House Media
Class SB 141 / Rauhenstein (Locobase 549)
Data confirmed and supplemented from [
], accessed 15 August 2006.
One of the first European engines fitted with a swing-link bolster. This engine had a short-wheelbase Haswell radius bar truck that worked well enough on the curves, but whose centering effect was unnoticeable on tangent track. Another curious feature on this open-footplate cabbage-stacker was locating the cylinders behind the leading truck altogether. The Stephenson link valve motion was unusually placed outside. The six names given were RAUHENSTEIN, BADEN, LIECHTENSTEIN, HIETZING, HETZENDORF, and BELVEDERE
This 1857 design was improved by Kamper. (see Grimming.)
