Bavarian B X

The B X steam engines of the Royal Bavarian State Railways (Königlich Bayerische Staatsbahn) were express train locomotives in Bavaria. The vehicles had an inside locomotive frame, the cylinders lay behind the carrying axle and the steam inlet pipes ran in front of the boiler. Twelve locomotives were delivered with compound engines; two with simple, two-cylinder engines. The latter were converted to compound working in 1896 however.
