Bavarian A I engines were German steam locomotives in service with the Royal Bavarian State Railways (Königlich Bayerische Staatsbahn) from 1841 to 1871.
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 examples were rebuilt into B I class 2-4-0 locomotives, four were rebuilt into C I class 0-6-0 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 the Munich–Augsburg Railway Company, 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.
