The Palatine T 4II was a class of saturated steam, tank locomotives operated by the Palatinate Railway.

They were to a large extent identical to the Class D XI from Bavaria, but the grate area and diameters of the carrying and coupled wheels were smaller. The rear coupled axle was housed in a Krauss-Helmholtz bogie, and the coal tanks were behind the driver's cab. It achieved its top speed on the level with a 400 tonne train.

The three examples that were built were given railway numbers 257 to 259 and the names Ulmet, Eschenau and Erdesbach. In 1925 the Deutsche Reichsbahn took all three machines over as DRG Class 98.4 with locomotive numbers 98 401 to 98 403. Until their retirement in 1933/34 the engines were stabled at Landau locomotive shed.

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.

The Bavarian Class D XII steam locomotives were manufactured by the firm of Krauss from 1897 for the Royal Bavarian State Railways. Ninety six of them were procured for service on the stub lines running from Munich into the mountains, but in reality they were stationed in many large Bavarian locomotive depots. Two engines were transferred to the Palatinate Railway (Pfalzbahn) in 1916, the remaining 94 later joined the Deutsche Reichsbahn fleet and were incorporated as DRG Class 73.0-1 with operating numbers 73 031–124.

The 10 examples of the Class D V steam engine belonging the Royal Bavarian State Railways were the first six-coupled tank locomotives in Bavaria. They were intended specifically for working the hilly route between Plattling and Eisenstein. Because they did not deliver the expected performance, however, they were soon relegated to shunting duties.

The little D IV was one of the most frequently seen tank locomotives in the stations of the Royal Bavarian State Railways. The Deutsche Reichsbahn took over almost all of them, 124 in total, of which 24 were from the Palatinate (Pfalz).

The physically identical Palatine and Bavarian Class R 4/4 engines of the Royal Bavarian State Railways were goods train tank locomotives with four coupled axles and no carrying axles. The first nine machines were built for the Palatinate Railway (Pfalzbahn) in 1913 and 1915 as the Palatine Class R 4, the remainder from 1918 to 1925 as Bavarian R 4/4 engines.

The six-coupled P 5 of the Palatinate Railway (Pfalzbahn) was to replace the four-coupled locomotives in the Palatinate. They were given a leading Krauss-Helmholtz bogie and a trailing bogie in order to achieve satisfactory weight distribution.

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

Class T 5 of the Palatinate Railway was a German, goods train, tank locomotive class with five coupled axles and no carrying axles.

<span class="mw-page-title-main">Palatine L 2</span>

The Palatine Class L 2 were a group of steam locomotives used on the Palatinate Railway in early 20th century Bavaria. They were built for the line between Speyer and Neustadt an der Weinstrasse. Because the engines were to be used double-headed, they had doors on the front and rear of the driver's cabs and an opening in the running plate. This enabled access to the locomotive from the train whilst running.

The German steam locomotive of Palatine Class Pts 2/2 of the Palatinate Railway was a one-off and was built by the firm of Maffei in Munich. Notable features were the high boiler and the locomotive frame used as a water tank. Coal was carried in two bunkers on the left and right of the driver's cab.

The DRG Class 99.10, formerly the Palatine Class Pts 3/3 H of the Palatinate Railway, was a German narrow gauge steam locomotive. It was the superheated version of the PtS 3/3 N. Unlike the saturated steam version the upper section of these engines was no longer glazed, otherwise they were broadly identical. They could carry up to 2.0 m3 of water and 1.2 t of coal.

<span class="mw-page-title-main">Palatine L 1</span>

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.

<span class="mw-page-title-main">Palatine P 3.I</span>

The German steam locomotives of Palatine Class P 3I were operated by the Palatinate Railway and were the first engines in Germany with a 4-4-2 (Atlantic) wheel arrangement. The two-cylinder saturated steam locomotives with inside cylinders had in addition to an inside bar frame a characteristic outer frame for the rear part of the locomotive, that partly covered the driving wheels. The valve gear was of the Joy type.

The locomotives of Palatine Class T 4I were saturated steam tank engines operated by the Palatinate Railway. Krauss delivered four of them in 1895 and a further three in 1897. The development of these engines had been based on the second batch of Bavarian D VIII engines and they differed only in a few dimensions: for example, the diameter of the carrying and coupled wheels was smaller. In addition they had a larger coal tank.

The Palatine T 3 was a class of goods train tank locomotives with a C n2t wheel arrangement in service with the Palatinate Railway. They had no running axles. They were incorporated into the Deutsche Reichsbahn as DRG Class 891 with operating numbers 89 101–121. Their design was based on that of the Bavarian D V.
