The Deutsche Reichsbahn had a standard passenger train tank engine with a wheel arrangement of 1'C1' or 2-6-2 and a low axle load, which was designated in their classification system as the DRG Class 64. The Class 64 was developed from 1926 onwards and it was built between 1928 and 1940. Many German manufacturers contributed to the series.
The locomotives of DRG Class 98.10 were superheated steam locomotives with the Deutsche Reichsbahn-Gesellschaft.
The Bavarian Class GtL 4/4 engines were superheated steam locomotives in service with the Royal Bavarian State Railways for duties on branch lines (Lokalbahnen).
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 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 Prussian T 18 was the last class of tank locomotives developed for the Prussian state railways. They were originally intended for services on the island of Rügen as replacements for Class T 12 and T 10 engines. They emerged when a class of locomotive was conceived in 1912 that was to handle express and passenger trains in border areas or in shuttle services on short routes. A tank engine design with symmetrical running gear was envisaged because, unlike a tender locomotive, it could run equally fast forwards and backwards and could be operated on return journeys without having to be turned on a turntable. Its power and top speed were to be the same as those of the P 8. Robert Garbe designed this 4-6-4 (2′C2′) tank locomotive for 100 km/h with a 17-ton axle load and contracted the Vulkan Werke in Stettin to build it. It was given the designation T 18.
In 1908 the Royal Württemberg State Railways placed an order with the Maschinenfabrik Esslingen for a powerful passenger tank locomotive. Classified as the Württemberg T 5, this superheated engine was designed for duties on Württemberg's main and branch lines and had the very long fixed wheelbase of 4,000 mm in order to give the locomotive smooth riding qualities. By 1920 a total of 96 engines had been manufactured. In 1919, three examples had to be give to France; the remaining 93 were taken over by the Deutsche Reichsbahn and 89 survived into the Deutsche Bundesbahn fleet. From 1959 they began to be retired. The last one was taken out of service in 1963 and was kept at Aulendorf as a museum engine until 1968. This last example was then scrapped as well.
The Baden VI b was the first German tank locomotive with a 2-6-2 wheel arrangement. It was developed by the firm of Maffei for the Grand Duchy of Baden State Railways in order to provide faster services on the Höllentalbahn. As a result, the first six batches were given a firebox sloping to the rear. One striking feature was also the connecting pipe between the two steam domes.
Locomotive No. 44 of the Brunswick State Railway Company was a tank locomotive for mixed passenger and goods traffic. The locomotive, built in 1934 by Krupp, had a 2-8-2T wheel arrangement and a two-cylinder superheated engine. Leading and trailing wheels were housed in a Bissel bogie. Rather unusual for such a locomotive were the smoke deflectors which were attached directly to the side tanks and extended as far as the front buffer beam.
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.
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.
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.
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.
The Prussian G 7.3 was a class of 2-8-0 locomotives of the Prussian state railways. The third class of the G 7 series, they were intended to power heavy goods trains on steep inclines, on which the permissible axle load was not yet that high. This affected for example, the Paderborn–Holzminden and Betzdorf–Siegen routes.
