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.

After the formation of the Deutsche Reichsbahn the engine was taken over and given the number '99 011'. It was retired by 1931.

Locomotives 9 and 10 of the Lokalbahn AG (LAG) were saturated steam locomotives that were built for the Murnau - Garmisch-Partenkirchen route opened in 1889.

The Bavarian Class PtzL 3/4 engines with the Royal Bavarian State Railways were rack railway locomotives whose cogwheel drive was designed for working on tracks with a Strub rack. In 1923 they were incorporated by the Deutsche Reichsbahn as DRG Class 97.1 in their numbering plan. The locomotives remained on their regular route between Erlau and Wegscheid until the closure of this rack railway in 1963. The last journey was on 5 January 1963. They were scrapped in April 1964 at Simbach am Inn.

<span class="mw-page-title-main">Bavarian D XII</span>

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 Bavarian Pt 2/4 N was a steam locomotive with the Royal Bavarian State Railways. It was developed in parallel with the Bavarian Pt 2/3 and for the same duties. Instead of a fixed carrying axle it was given a bogie. This change brought no advantage, so the more cost-effective Pt 2/3 was favoured. The two Pt 2/4 N engines were nevertheless taken over by the Reichsbahn, but were retired by 1928.

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).

<span class="mw-page-title-main">Palatine R 4/4</span>

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.

<span class="mw-page-title-main">Palatine P 5</span>

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 Class S 2/5 express locomotives of the Royal Bavarian State Railways were the first steam engines in Germany to be built with full-length bar frames. The prototypes for this type of frame were the two locomotives imported in 1900 from Baldwin Locomotive Works in the US, that had been similarly classified as the S 2/5.

The Bavarian Pts 3/42-6-0T steam locomotives of the Royal Bavarian State Railways were employed on the steam 'tramway' between Altötting and Neuötting. A total of four machines were built, nos. 1101, 1102 and 1103 in 1906 and no. 1104 not until the retirement of no. 1102 in 1922. They had a covered driving gear, a high boiler with water tanks located beneath it, gangways and a railing for the running plate. The engines carried 2.5 m3 (88 cu ft) of water and 0.5 tonnes of coal on board.

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

The Bavarian Class D IV was a German steam locomotive with the Bavarian Eastern Railway.

The Baden Class I b locomotives of the Grand Duchy of Baden State Railways were built for the pontoon bridges from Heidelberg to Speyer. Altogether three of these engines were on duty, of which two had been taken over from the Palatinate Railway in 1874. A third machine was procured directly from the Maschinenbau-Gesellschaft Karlsruhe in 1893.

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

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.
