Due to increased train weights in express train traffic, the most influential designer for Austrian steam locomotive construction, Ing. Dr. h.c. Karl Gölsdorf, developed a new express locomotive with the wheel arrangement 1'C2' in 1906. This, compared to the Pacific type popular in many countries, was an "inverted" axle arrangement, which made it possible to accommodate a large upright boiler with a wide grate. Together with the weighty four-cylinder compound engine, it was possible to create a high-performance locomotive despite the low Austrian axle load limit of only 14.5 t. This locomotive is considered by many railway enthusiasts to be the most beautiful steam locomotive in Austria.
Whereas the first 11 engines were delivered in wet steam design, the other 90 examples of this type were put into service as series 310 superheated steam locomotives and used by the kkStB mainly on the Nordbahn, the Franz-Josefsbahn and the Westbahn between Vienna and Salzburg as a high-quality passenger train service.
The "Russian Iron" was an alternative to primed and painted sheet metal in the early railway eras, but also represented an aesthetic element. It was only used around locomotive areas with high heat radiation, such as the panelling on the boiler and cylinder.
The black and white photos at our disposal suggest that locomotives of the 310 series also received "Russian Iron" panelling. Images in colour also support this assumption. In terms of colour design, the black-painted smoke chamber panelling provides striking accents. This contributes to the highly attractive appearance of this unusual locomotive design.
