Bavarian A I engines were German steam locomotives in service with the Royal Bavarian State Railways
Royal Bavarian State Railways
As a nation-state, Germany did not come into being until the creation of the German Empire in 1871 from the various German-speaking states such as Prussia, Bavaria, Saxony, Baden and Württemberg. By then each of the major states had formed its own state railway and these continued to remain...
(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 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
