Bavarian D IX
DRG Class 70.71Number(s): DRG 70 7101–7154 Quantity: 55 Manufacturer: Maffei Year(s) of manufacture: 1888–1899 Retired: 1932 Wheel arrangement: 2-4-0 Axle arrangement: 1B n2 Gauge: 1.435 mm Length over buffers: 8,440 mm Service weight: 35.8 t Adhesive weight: 24.8 t Axle load: 12.4 t Top speed: 65 km/h Driving wheel diameter: 1,340 mm Leading wheel diameter: 1,040 mm Cylinder bore: 330 mm Piston stroke: 500 mm Boiler Overpressure: 12 bar Grate area: 1.20 m² Evaporative heating area: 60.20 m² The D IX steam locomotive was manufactured by the firm of Maffei between 1888 and 1899 for the Royal Bavarian State Railways (Königlich Bayerische Staatsbahn). They were used on the route from Reichenhall via Freilassing to Salzburg. After one engine had been successfully employed on the route to Berchtesgaden, the vehicles were also deployed on the suburban lines of Augsburg, Munich and Nuremberg.
There were scarcely any differences between the various build series. Not until 1896 were minor changes made to the heating areas, the weights and the coal and water capacities. The rigid mounting of the driving and carrying wheels and the location of the cylinder just in front of the carrying wheel did not prove a success. The D IX locomotives could haul 170 t on the flat at a speed of 65 km/h, on routes with a 2 % incline they could manage 95 tons at 20 km/h.
Apart from one engine, which had already been retired by Bavaria, the Reichsbahn took on all the engines. Some were taken out of service even before 1925, the rest had followed by 1932.
Unfortunately no examples of the Bavarian D IX have been preserved.
