DRG Renumbering Plan
In 1922 the Deutsche Reichsbahn began to develop a renumbering plan to standardize the numbering of steam locomotives that had been taken over from the state railways (''Länderbahnen''). Its basis was the corresponding DRG classification system. The first renumbering plan in 1922 envisaged more class numbers than the later plans. The development of this scheme was discontinued because it was seen that there would be problems in practically adopting it. The second, provisional, renumbering plan of 25 July 1923 was very like the final version of 1925 in its basic structure. It incorporated space for the new standard locomotives ('' Einheitslokomotiven'') that were planned. The third and final renumbering plan of 1925 differed from its predecessor primarily in that all the locomotives retired up to that point – in some cases entire classes – were deleted; in addition several mistakes in the numbering were corrected. With the exception of Bavarian classes, new locomotives built a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Reichsbahn
The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The ''Deutsche Reichsbahn'' has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932"; nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history". Overview The company was founded on 1 April 1920 as the ("German Imperial Railways") when the Weimar Republic, which still used the nation-state term of the previous monarchy, (German Reich, hence the usage of the in the name of the railway; the monarchical term was ), took national control of the German railways, which had previously been run by the German states. In 1924 it was reorganise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prussian S 8
The Prussian S 9 was an express steam locomotive with the Prussian state railways, first built in 1908. It had a 4-4-2 (''Atlantic'') wheel arrangement and a four-cylinder compound engine. It was developed by the firm of Hanomag in Hanover who delivered a total of 99 engines of this class. There were also some high-speed trials locomotives which were classified as S 9s, but did not belong to this particular class. These included two cab-forward 4-4-4 locomotives Altona 561 and 562. Although at the time superheated technology was widespread, the state of Prussia still wanted to have saturated steam engines delivered by Hanomag. The locomotives procured as a result had a very powerful boiler and, at 4 m2, the largest grate area of any Prussian steam locomotive. The quantity of steam generated was however more than the high-pressure cylinders could cope with. As a result, the performance of the S 9 was little better than the considerably smaller superheated locomotive, the Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bavarian C V
The Class C V (pronounced ''C 5'') of the Royal Bavarian State Railways (''Königlich Bayerische Staatsbahn'') was one of the first European express train locomotives with a 4-6-0 wheel arrangement. In 1896 Maffei built a steam locomotive for the Bavarian state exhibition at their own expense. It had coupled wheels with a 1,640 mm diameter and was therefore regarded as a multi-purpose locomotive. After the exhibition the Bavarian State Railway purchased this locomotive and, after thorough testing, ordered more engines of this type, albeit in a stronger version and with a 1,870 mm coupled wheel diameter, i.e. as genuine express train locomotives. Between 1899 and 1901 Maffei supplied 42 examples. The C V had a four-cylinder de Glehn compound engine. Its low-pressure cylinders were external, operating on the second coupled axle, and were located between the bogie and the first coupled axle. The high-pressure cylinders were internal and worked the first coupled axle. The engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prussian S 10
The Prussian Class S 10 included all express train locomotives in the Prussian state railways that had a 4-6-0 wheel arrangement. There were four sub-classes: the S 10, S 10.1 (with 1911 and 1914 variants) and S 10.2. Prussian S 10 As a result of the lack of powerful express locomotives in the first decade of the 20th century, the Prussian state railways ordered the Class S 10 locomotives from Schwartzkopff. This engine was an evolutionary development of the passenger train locomotive, the Prussian P 8, which can be seen from the similarity in their locomotive frames. Unlike the P 8, however, the S 10—inspired by the Saxon XII H—had a four-cylinder engine with simple expansion. Between 1910 and 1914 a total of 202 locomotives were built. The two prototypes were initially designated as S 8 class and only reclassified in 1912 to S 10. The Lübeck-Büchen Railway took delivery of five similar, albeit somewhat less powerful, machines that they also designated as the S 10. Ov ...

Oldenburg S 10
The express train locomotives of Oldenburg Class S 10 were built for the Grand Duchy of Oldenburg State Railways for duties on the Bremen–Oldenburg–Wilhelmshaven line, which was the most important express route in Oldenburg. They were amongst the few locomotives of this railway company that were not based on those of the Prussian state railways, because the light railway track dictated that they had to have an average axle load of no more than 15 t which was lower than that on comparable Prussian vehicles. The three vehicles of this class were built by Hanomag from 1917 and had a 2-6-2 (''Prairie'') wheel arrangement which was rare for Germany. They had Lentz valve gear which was typical of Oldenburg. The engines had an uneven distribution of load, however, as well as poor riding qualities and were often bedevilled with boiler problems. In addition, an incorrect matching of the radiative and tube heating areas led to leaks in sides of the tubes. The three S 10 engines wer ...

Bavarian S 2/6
The Royal Bavarian State Railways' sole class S 2/6 steam locomotive was built in 1906 by the firm of Maffei in Munich, Germany. It was of 4-4-4 wheel arrangement in the Whyte notation, or 2'B2' h4v in the UIC classification scheme, and was a 4-cylinder, von Borries, balanced compound locomotive. It was initially assigned No. 3201. The inspiration was partly the two Prussian S 9 cab forward 4-4-4s of two years previously. Unlike those locomotives, the S 2/6 was strictly conventional in all respects apart from wheel arrangement, driving wheel size and streamlining. Many aspects of the design were borrowed from the earlier Maffei design of the Baden IId 4-4-2 class; Anton Hammel was the chief designer for both. The locomotive was designed and built in only 4 months. Design For the first time in Germany, a cast steel locomotive frame after American practice was used. This was lighter and more slender for the same degree of strength, and contributed to the locomotive's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baden II D
Baden (; ) is a historical territory in South Germany, in earlier times on both sides of the Upper Rhine but since the Napoleonic Wars only East of the Rhine. History The margraves of Baden originated from the House of Zähringen. Baden is named after the margraves' residence, in Baden-Baden. Hermann II of Baden first claimed the title of Margrave of Baden in 1112. A united Margraviate of Baden existed from this time until 1535, when it was split into the two Margraviates of Baden-Durlach and Baden-Baden. Following a devastating fire in Baden-Baden in 1689, the capital was moved to Rastatt. The two parts were reunited in 1771 under Margrave Charles Frederick. The restored Margraviate with its capital Karlsruhe was elevated to the status of electorate in 1803. In 1806, the Electorate of Baden, receiving territorial additions, became the Grand Duchy of Baden. The Grand Duchy of Baden was a state within the German Confederation until 1866 and the German Empire until 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxon X H1
The Saxons ( la, Saxones, german: Sachsen, ang, Seaxan, osx, Sahson, nds, Sassen, nl, Saksen) were a group of Germanic * * * * peoples whose name was given in the early Middle Ages to a large country ( Old Saxony, la, Saxonia) near the North Sea coast of northern Germania, in what is now Germany. In the late Roman Empire, the name was used to refer to Germanic coastal raiders, and as a name similar to the later "Viking". Their origins are believed to be in or near the German North Sea coast where they appear later, in Carolingian times. In Merovingian times, continental Saxons had been associated with the activity and settlements on the coast of what later became Normandy. Their precise origins are uncertain, and they are sometimes described as fighting inland, coming into conflict with the Franks and Thuringians. There is possibly a single classical reference to a smaller homeland of an early Saxon tribe, but its interpretation is disputed. According to this proposal, th ...

Saxon X V
The Royal Saxon State Railways designated four-coupled, ''Atlantic'' ( 4-4-2) express locomotives as Class X \textstyle \mathfrak and the Deutsche Reichsbahn subsequently grouped these locomotives into DRG Class 14.2 in 1925. History In 1900 the Sächsische Maschinenfabrik engineering works built the first two express locomotives of the new four-coupled, ''Atlantics'' with a four-cylinder compound engine. One of the locomotives was displayed at the Paris World Exhibition in 1900 and was awarded the Grand Prix. The Royal Saxon State Railways took over the two prize-winning locomotives and procured another 13 up to 1903 that differed from the prototypes, particularly in terms of the diameter of the carrying axles. They were the largest and most powerful locomotives in Saxony to that point. The X V was employed on express train duties on the plains where its riding qualities and economy were impressive. In 1920 the Deutsche Reichsbahn took over all 15 engines and gave them the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palatine P 4
The Class P 4 steam locomotives of the Palatine Railways were express train locomotives with a 2'B1' (Atlantic) axle arrangement and a four-cylinder compound engine. A total of eleven locomotives were built by Maffei, numbers 286–291 in 1905 and 302–305 and 433 in 1906. They replaced the P 3.1 in express train service. The locomotives were initially fitted with Pielock superheaters, but after a few years they had to be removed again due to corrosion damage. From then on the locomotives operated as wet steam engines. The P 4 was one of the first locomotives in Germany with bar frames. It was based on the Bavarian class built in 1903, the S 2/5; up to the second coupling axle, both types were almost the same apart from details and minor dimensional deviations. However, the P 4 had - unlike the S 2/5 - a wide firebox which was arranged completely behind the coupling wheels. For this reason, the distance between the coupling axle and the rear carrying axle had to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bavarian S 2/5
The Class S 2/5 express locomotives of the Royal Bavarian State Railways (''Königlich Bayerische Staats-Eisenbahnen'') were the first steam engines in Germany to be built with full-length bar frames (''durchgehendem Barrenrahmen''). 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. History In 1904, Maffei built ten engines that shared many of the same components as the S 3/5, which was developed in parallel. For example, they did not use a wider firebox, which would have been possible given the wheel arrangement, in order to be able to use one that could be used on the S 3/5. So the firebox was only around 90 mm wider than the bar frame of the locomotive. For manufacturing reasons the sole bar was still not made of one piece, but forged from several bars. For the first time in Bavaria a driving wheel diameter of 2,000 mm was chosen i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vauclain Compound
The Vauclain compound was a type of compound steam locomotive that was briefly popular circa 1900. Developed at the Baldwin Locomotive Works, it featured two pistons moving in parallel, driving a common crosshead and controlled by a common valve gear using a single, complex piston valve. Advantages and disadvantages The claimed advantage for this arrangement, as with other compounding arrangements, was greater economy due to lower fuel and water consumption. In practice uneven forces at the crosshead produced excess wear, with increased maintenance costs thus offsetting any fuel economies. The integration of the compounding system into the smokebox saddle made conversion to conventional engines straightforward, so most Vauclain compounds were so converted and led normal lives thereafter. The only known operable example is Manitou and Pikes Peak Railway No. 4, which is preserved on-site along with the static display of its sister #5. Design The key to the Vauclain compound is i ...
