Three manufacturers were awarded a contract to build eight locomotives each, with the stipulation that the components of the different machines had to be interchangeable with one another. The engines achieved a speed of 33 km/h on a line with an incline of 1:200. The first engine was retired in 1871 and scrapped. Five other examples were rebuilt into B 1 locomotives and four were sold. The last one was scrapped in 1874.
They were coupled with 2 T 3,35 tenders.
Der Münchner (a Münchner is a man from Munich) was a Bavarian Class A I engine with the number 25. It was originally built for a private railway company which ran the route between Munich and Augsburg. In 1844 the line was taken over by the state railway and the engine was transferred into state ownership. A large part of the locomotive came from England, which can be seen from the typically English 'pear' shape of the outer firebox.
It was coupled with a 2 T 3 tender.
