The Nordhausen-Wernigerode Railway Company incorporated twelve Mallet locomotives into its fleet as Numbers 11 to 22. In 1950 the remaining locomotives were renumbered as Class 99.590 by the Deutsche Reichsbahn.
In 1897, shortly after the railway company's foundation, the first of a new batch of locomotives was built for the NWE by Arnold Jung in Jungenthal. It was a Mallet engine, numbered NWE 11, with the front two axles in an inside frame and the rear two axles in an outside frame. The fleet quickly grew to 12 locos of which nine were made by Jung from 1897 to 1901 and three by the Mecklenburgische Maschinen- und Waggonbau AG in Güstrow in 1897 . The locomotives were very reliable, but six had to be handed over to the military railways during the World War I (including all three engines built in Güstrow) for use in France, and they never returned from their wartime duties. [1] The remaining six engines received new, larger boilers with a higher performance. In 1927, locomotive NWE 12II suffered a derailment in Thumkuhlenthal upon which it fell off the high embankment. The engine, one passenger coach and the luggage van were so badly damaged that they had to be dismantled on the spot. [2]
In the mid-1950s, the first three newly designed locomotives ( Neubauloks ) of DR Class 99.23–24 came to the Harz Railway. As a result, the remaining five Mallets were no longer needed on the Nordhausen–Wernigerode line and were transferred to the Selke Valley Railway which suffered from a shortage of motive power. Two were scrapped - 99 5905 in 1975 due to damaged cylinders and an expired boiler certificate [1] and 99 5904 in 1990 reportedly due to a damaged axle - but the remaining three are still in the fleet. 99 5901 suffered an accident in 1977, but could be repaired. After all passenger trains on the Harz narrow gauge lines were fitted with compressed air brakes, the HSB mallets could not be used for passenger duties any more and were stabled. Therefore, while 99 5901 passed inspection in 1991, it could only be used as a helper engine when the Brocken line was reopened. Only in 1992, suitable compressed air braking equipment was found for two engines. 99 5903 was converted first, followed by 99 5901 in 1993. These engines were repainted in their historic green livery with yellow ornamentation. [2]
In addition, they were given their old numbers again: NWE 11 and NWE 13II. 99 5901 was repainted in black in 1998, and received a new, more powerful boiler in 2002. No. 99 5902 was converted to compressed air brakes in 2000. It has now the number NWE 12III and runs in green livery. After its operational certificates expired, maintenance on no. 99 5903 has been deferred.
Harz Narrow Gauge Railways currently operate the following engines of this type:
A similar locomotive is no. 99 5906, but with the rear axles mounted in an inside frame.
The Mallet locomotive is a type of articulated steam railway locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919).
The Selke Valley Railway (Selketalbahn), Gernrode-Harzgerode Railway and the Anhalt Harz Railway were different names for the metre gauge railway in the Lower Harz, Germany, originally owned by the Gernrode-Harzgerode Railway Company.
The Harz Narrow Gauge Railways is a railway company that operates a 1,000 mmmetre gauge network in the Harz mountains, in central Germany. The company was formed after the Second World War as a merger of two earlier companies. It owns about 140 kilometres of track, connecting the principal towns of Wernigerode, Nordhausen and Quedlinburg and several smaller settlements in the area. Much of the network is steeply graded and picturesque, but its most popular destination is the Brocken, the highest mountain in the region. The company runs a significant number of its trains with steam haulage, mostly employing 1950s vintage 2-10-2 tank locomotives, hauling traditional open-platform bogie carriages. The company is mainly owned by the various local authorities whose territories it serves.
The Harz Railway or Trans-Harz Railway was formerly the main line of the Harz Narrow Gauge Railways and runs north to south right across the Harz Mountains from Wernigerode to Nordhausen. However, the tourist attraction of the Brocken, the highest mountain in the Harz, is so great that the Brocken Railway is effectively the main line today. The Trans-Harz Railway joins up with the Selke Valley Railway to Quedlinburg at Eisfelder Talmühle where all trains are organised to make good connections.
The Brocken Railway is one of three tourist metre gauge railways which together with the Harz Railway and Selke Valley Railway form the Harz Narrow Gauge Railways railway network in the Harz mountain range of Germany.
The Bavarian Class Gt 2×4/4 engine of the Royal Bavarian State Railways, was a heavy goods train tank locomotive of the Mallet type. It was later designated the DRG Class 96 by the DRG, DB and DR.
The three engines of DRG Class 99.22 were standard, narrow gauge locomotives (Einheitsloks) in service with the German Reichsbahn. They had operating numbers 99 221 to 99 223.
The German Class 99.73-76 engines were standard locomotives (Einheitslokomotiven) in service with the Deutsche Reichsbahn for Saxony's narrow gauge railways. Together with their follow-on class, the DR Class 99.77-79, they were the most powerful narrow gauge locomotives in Germany for the 750 mm track gauge.
The steam locomotives of Bavarian Class LE were narrow gauge engines with the Royal Bavarian State Railways.
The engines of DR Class 99.23 are metre gauge tank locomotives, that were procured by the Deutsche Reichsbahn (DR) in East Germany from 1954 to 1956. When they entered service they had operating numbers 99 231–99 247. Today they are numbered 99 7231–99 7247.
The four-axled, driving railcars NWE T 1 to 3 were intended to provide more cost-effective railway services for the Nordhausen-Wernigeroder Eisenbahn-Gesellschaft during times of low traffic demand. Only the T 1 had seats, the other two only a luggage compartment.
The Nordhausen-Wernigerode Railway Company or NWE was the second railway company to be founded in the Harz mountains in Germany, after the Gernrode-Harzgerode Railway Company. On 15 June 1896 the NWE was formed by the Vereinigten Eisenbahnbau- und Betriebs-Gesellschaft in Berlin, who also ran its operations. As early as 1896 the first section of this narrow gauge Harz Railway ('Harzquerbahn') was opened, followed in 1898 by the Brocken Railway (Brockenbahn), which was also narrow gauge. On 1 April 1908, the NWE took over operations from the Vereinigten Eisenbahnbau- und Betriebsgesellschaft.
The Grand Duchy of Mecklenburg Friedrich-Franz Railway grouped early, 2-4-0, passenger train locomotives from the Friedrich-Franz Railway into its Class III.
Steam traction was the predominant form of motive power used by the Deutsche Reichsbahn on its narrow-gauge railways. For certain duties diesel locomotives were also used, albeit these were usually second-hand or rebuilt engines.
The EAR 59 class is a class of oil-fired 1,000 mm gauge Garratt-type articulated steam locomotives. The 34 members of the class were built by Beyer, Peacock and Company in Manchester, England, for the East African Railways (EAR). They entered service in 1955–56, and were the largest, heaviest and most powerful steam locomotives to operate on any metre gauge railway in the world.
NWE Nos. 6 and 7, later Class 99.610, are narrow gauge tank locomotives with a C axle arrangement that belonged to the Nordhausen-Wernigerode Railway.
The Gernrode-Harzgerode Railway Company or GHE was a private railway company in Germany that operated the Selke Valley Railway. It had a junction with the network of the Nordhausen-Wernigerode Railway Company (NWE) at Eisfelder Talmühle station.
The HK 94–100 is a series of four-axled, German Mallet locomotives with a 1,000 mm track gauge.
The NWE No. 21II, later DR 99 6001 is a narrow gauge steam locomotive that was built in 1939 for a track gauge of one metre and is still on duty with the Harz Narrow Gauge Railways (HSB) today.
The Saxon VI K were a class of 750-mm gauge 0-10-0T locomotives of the Royal Saxon States Railways with a gauge of 750 mm. In 1925 the Deutsche Reichsbahn (DRG) grouped the locomotives into class 99.64–65; from 1923 to 1927 the procured more locomotives of this type which were grouped in to class 99.67–71.
