 Bavarian S 3/6

The Class S 3/6 steam locomotives of the Royal Bavarian State Railways (later Class 18.4-5 of the Deutsche Reichsbahn) were express train locomotives with a 4-6-2 Pacific (Whyte notation) or 2'C1' (UIC classification) wheel arrangement.Of all the state railway locomotives, these engines are remarkable because they were made over a period of almost 25 years, even during the Deutsche Reichsbahn era.
