what is it?
The B IXs of the Royal Bavarian State Railways (Königlich Bayerische Staatsbahn), built from 1874, were the first express train locomotives in Bavaria. (N.B. The engines described here are not to be confused with the B IX steam engines built in 1870 and described under Bavarian B IX (1870).) As a result of the boiler being positioned low and the rear driving axle being under the outer firebox there was no longer any overhanging weight and the speed of the engine could be increased to 90 km/h. The locomotive could also haul a 150-ton train on the level at a speed of 70 km/h.
