Model: HO gauge AC. Austrian Federal Railways steam locomotive 310.20. Drive on two axles of the tender and via cardan shaft on all three driving axles of the locomotive. Version with finely detailed running gear, filigree reproduction of the control system, opening smoke box doors and many extra details.

Prototype: 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' from 1906. This axle arrangement, which was "upside down" compared to the Pacific design popular in many countries, made it possible to accommodate a large standing boiler with a wide grate. Together with the massive four-cylinder compound engine, it was possible to create a highly powerful machine despite the low Austrian axle load limit of only 14.5 t, which is considered by many railway enthusiasts to be the most beautiful steam locomotive in Austria. While the first 11 locomotives were delivered in wet steam version, the other 90 of this type were put into service as class 310 superheated steam locomotives and used by the kkStB mainly on the Northern, Franz-Josefs and Western Railway between Vienna and Salzburg in high-quality passenger service. In the early railway eras, the "Russian bright sheet", or "blue sheet" for short, was an alternative to primed and painted sheet metal, but also an aesthetic element. It was only used around areas of high heat radiation, such as the linings of boilers and cylinders. Black and white pictures suggest that locomotives of the 310 series also had "blue sheet" cladding. Coloured pictures also support this assumption. The black-painted smokebox lining sets a special accent in the colour scheme. The appearance of this unusually designed locomotive thus appears very successful.
