Thus the list includes partly dismantled or badly corroded locomotives, the technical condition of which cannot really be accurately conveyed in their descriptions.
In addition the following common German abbreviations are used: Replicas of historic engines, that cannot be grouped into a specific class.
On the introduction of computerised (EDP) numbers, the coal-fired locomotives were renumbered to the 011 series and the oil-fired versions to 012.
11331 The Class 03 engines were built between 1930 and 1937 as express locomotives for routes that were only suitable for axle loads up to 18 tonnes.
The Deutsche Reichsbahn grouped those express train, tender locomotives with an axle arrangement of 2'C1' (Pacific), taken over from the state railways, into Class 18.
The remaining locomotives in the Deutsche Reichsbahn (East Germany) incorporated into Class 02 on the change-over to computerised numbers.
This involved the Reichsbahn locomotives procured roughly between 1927 and 1930 of Bavarian S 3/6 series l to o, that were reclassified into DB Class 18.6.
The DRG Class 19 were eight-coupled express train tender locomotives with a 1′D1′ axle arrangement taken over from the Royal Saxon State Railways.
In Class 34 of the Deutsche Reichsbahn are grouped state railway, passenger train tender locomotives with an axle arrangement of 1'B.
1962 AW Lingen: Cabin tender Between 1958 and 1962 the Deutsche Reichsbahn (East Germany) had 208 locomotives of Class 50 fitted with newly designed boilers with a mixer-preheater, larger evaporative heating areas and improved suction draught.
In the early 1950s, 25 DRB Class 52 locomotives were converted to Wendler brown coal firing at RAW Stendal.
The Deutsche Reichsbahn grouped all ex-state railway, eight-coupled, goods train, tender locomotives with no carrying wheels into their Class 55.
The DRG Class 57 encompassed various ex-state railway, goods train, tender locomotives with E axle arrangements.
The DRG's Class 58 includes various ex-state railway, goods train, tender locomotives with an axle arrangement of 1'E (Decapod).
Because they were used by almost all the Länderbahn railway administrations (except Bavaria), they are often described as the first German Einheitslokomotiven, despite oft-repeated comments to the contrary.
The Baden G 12 of the Royal Württemberg State Railways was based on the Prussian G 12.1 and a goods train locomotive class with a 1'E axle arrangement built by Henschel for the Royal Ottoman General Division of Military Railways (Kaiserlich Ottomanische Generaldirektion of the Militäreisenbahnen or C.F.O.A.).
The DB Class 66 was planned by the Deutsche Bundesbahn for fast freight and passenger train services on main and branch lines.
The DRG Class 75 swept up ex-state railway, passenger train, tank locomotives with an axle arrangement of 1'C1'.
The 39 tank engines of DRG Class 80 emerged between 1927 and 1928 as standard, shunting locomotives for the Deutsche Reichsbahn.
These Hanomag-built locomotives of Class 81 were standard goods train tank engines with the Deutsche Reichsbahn with a Dh2t axle formula.
The DB Class 82 was a so-called Neubaudampflokomotive built by the Deutsche Bundesbahn for shunting and freight services.
It was a tank engine with the axle formula E, built in 1950 and 1951 by the firms of Krupp and Henschel, and in 1955 by the Maschinenfabrik Esslingen.
The DRG Class 85 was a goods train tank engine and Einheitslokomotive built for the Deutsche Reichsbahn.
The DRG Class 86 was a standard, goods train, tank locomotive with the Deutsche Reichsbahn with a 1'D1' axle arrangement.
The Deutsche Reichsbahn grouped several variants of the T 9 steam locomotives from the Prussian state railways as Class 90.
The Prussian state railways' T 9.1 engines were goods train tank locomotives with an axle arrangement of C1'.
Class 95 incorporates tank locomotives of the Deutsche Reichsbahn and its successor administrations that have an axle arrangement of 1'E 1'.
It was procured by the Deutsche Reichsbahn in 1922 for heavy goods train duties on steep main line routes.
After the First World War it developed 6 locomotive classes for various duties because many branch line and private railways were forced to modernise their obsolete engine fleets.
Industrial and field railways (Feldbahnen) in Germany mostly run on 600 mm (1 ft 11+5⁄8 in) wide track.
