 In order to reduce wear and tear on the tyres and brake shoes during descents, the engines were fitted with Riggenbach counter-pressure brakes.In 1925 the Deutsche Reichsbahn took over all eight locomotives and grouped them into DRG Class 92.1 in their numbering plan.After the Second World War they ended up in the Deutsche Bundesbahn, where they were retired between 1946 and 1948 or sold as industrial locomotives.
