German BR23 2-6-2

German BR23 2-6-2

The steam locomotives of Class 23 were German passenger train locomotives developed in the 1950s for the Deutsche Bundesbahn. They had a 2-6-2 wheel arrangement and were equipped with Class 2'2' T 31 tenders. They were designed to replace the once ubiquitous Prussian P 8 engines that had been built between 1908 and 1924 and, in their day, were the most numerous post-war replacement class.

(C) General Notes
the steam sounds have been recordered using real sound from the original steam engine in action
Each engine we have recorded has a distinct 'personality', so a particular locomotive example may sound slightly different due to unique e.g. tappet, crank-rate shell vibrations and exhaust-stack, chuff differences. Horns and bells are often moved between locomotives.
