The Bavarian Class A, later B IX were German steam locomotives with the Bavarian Eastern Railway (Bayerische Ostbahn).

Contents

Crampton version

The engines had an external frame with outside drive and valve gear. They had the smallest wheel diameter (1,828 mm) of any locomotive of this type in the whole of Germany. Between 1869 and 1871 all the engines were rebuilt in Regensburg and were given a 1 B axle arrangement. They were then given locomotive numbers 1081–1092.

Stephenson version

The second series of this class was built to a Stephenson design. They did not differ greatly in terms of boiler and driving gear from the locomotives of the first series. These engines were also converted in Regensburg between 1870 and 1871 to vehicles with a 1B axle formula. In addition the boiler overpressure was raised from 6 to 10 bar. They were then given locomotive numbers 1069–1080.

Tender

Both series were equipped with 3 T 7 tenders.

DRB Class 50

The DRB Class 50 is a German class of 2-10-0 locomotive, built from 1939 as a standard locomotive (Einheitsdampflokomotive) for hauling goods trains. It had one leading axle and five coupled axles and was one of the most successful designs produced for the Deutsche Reichsbahn.

Bavarian PtL 2/2

The Class PtL 2/2 locomotives of the Royal Bavarian State Railways were light and very compact superheated steam locomotives for operation on Bavarian branch lines. There were three types in total, of which two were transferred to the Deutsche Reichsbahn-Gesellschaft as Class 98.3 tank locomotives and even survived to join the Deutsche Bundesbahn fleet after the Second World War.

Bavarian S 3/6

The Class S 3/6 steam locomotives of the Royal Bavarian State Railways were express train locomotives with a 4-6-2 Pacific or 2'C1' wheel arrangement.

Bavarian ML 2/2

The Class ML 2/2 locomotives of the Royal Bavarian State Railways were light and very compact superheated steam locomotives designed for services on branch lines (Lokalbahnen). They were a rival design by Maffei to the Bavarian PtL 2/2 or Glaskasten locomotives built by Krauss.

Bavarian D VIII

The Bavarian Class D VIII were saturated steam locomotives with the Royal Bavarian State Railways.

Bavarian Gt 2×4/4

The Bavarian Class Gt 2×4/4 engine of the Royal Bavarian State Railways, was a heavy goods train tank locomotive of the Mallet type. It was later designated the DRG Class 96 by the DRG, DB and DR.

Bavarian D VI

The Bavarian Class D VI were German, 0-4-0, steam locomotives of the Royal Bavarian State Railways. They were light, twin-coupled, saturated steam, tank engines. Maffei supplied the first 30 locomotives from 1880 to 1883, and Krauss delivered a further 23 up to 1894.

Bavarian B IX

The B IXs of the Royal Bavarian State Railways, built from 1874, were the first express train locomotives in Bavaria.

Bavarian S 2/5 (Vauclain)

The Class S 2/5 locomotives operated by the Royal Bavarian State Railways included two express train, steam locomotives of American origin which were fitted with Vauclain compound engines.

The Bavarian Class E I steam locomotives operated by the Royal Bavarian State Railways encompassed four different variants of saturated steam, goods train locomotive with a 2-8-0 wheel arrangement.

The Bavarian C II was an early German steam locomotive operated by the Royal Bavarian State Railways.

The Einheitsdampflokomotiven, sometimes shortened to Einheitslokomotiven or Einheitsloks, were the standardized steam locomotives built in Germany after 1925 under the direction of the Deutsche Reichsbahn-Gesellschaft. Their manufacture made extensive use of standard design features and components.

The steam locomotives of Bavarian Class LE were narrow gauge engines with the Royal Bavarian State Railways.

Prussian G 10

The Prussian G 10 was a German goods train, steam locomotive, whose design was based on a combination of the running and valve gear from the Prussian T 16 and the boiler from the Prussian P 8. In developing the G 10, however, the T 16 running gear with side play on the first and fifth axles was modified. The T 16 was also subsequently built with this modified configuration and called the Prussian T 16.1. The G 10 was intended for heavy goods train duties on main lines, but as a result of its low axle load it could be employed more flexibly than its equally powerful cousin, the Prussian G 8.1. The G 10 was occasionally even used in passenger train service.

The steam locomotives of Alsace-Lorraine Class B 1 were procured by the Imperial Railways in Alsace-Lorraine in 1871. In 1906 they were reorganised into Class P 1.

The Prussian T 9 was a class of German steam locomotive which included several types of tank engine, all with six coupled wheels and two carrying wheels operated by the Prussian state railways.

The narrow gauge steam locomotives of Palatine L 1 and Pts 3/3 N of the Palatinate Railway were procured for lines in the area of Ludwigshafen, Neustadt an der Weinstrasse and Speyer. On the formation of the Reichsbahn the engines were given the running numbers 99 081 to 99 093.

Saxon V V

The Saxon Class V was a triple-coupled, goods train, tender locomotive operated by the Royal Saxon State Railways. In 1925, the Deutsche Reichsbahn regrouped the locomotives 25 into their DRG Class 53.6–7.
