The B VIII steam engines of the Royal Bavarian State Railways (Königlich Bayerische Staatsbahn) were tender locomotives.
This class was a forerunner of the first Bavarian express train locomotive. It was equipped with an inside Stephenson valve gear, inside steam chests, detachable cranks, (Aufsteckkurbel) and a full outside frame (aussenliegender Füllrahmen). The firebox was supported in order to provide a better distribution of weight.
They were equipped with Bavarian 3 T 9 tenders.
