The Nordhausen-Wernigeroder Eisenbahn-Gesellschaft (NWE) added twelve Mallet locomotives with the numbers 11 to 22 to their inventory. From 1950 the locomotives were designated as the 99.590 series by the Deutsche Reichsbahn .
history
Shortly after the founding year, the second series for the NWE was built by Arnold Jung in Jungenthal in 1897 . They were mallet locomotives . The NWE classified the first locomotive as NWE 11. The stock grew very quickly to twelve locomotives, nine of which were built by Jung and three by Mecklenburgische Waggonfabrik-Aktiengesellschaft in Güstrow . The locomotives were very reliable, but in the First World War six locomotives (including all locomotives from Güstrow) had to be handed over to the Heeresfeldbahnen . They never came back from their assignment there.
In 1927 a locomotive (NWE 12 II ) had an accident in Thumkulenthal. The locomotive, a passenger car and the baggage car were so badly damaged that they had to be dismantled on the spot. In the mid-1950s, the new locomotives (99.23-24) came to the Harzquerbahn . Therefore, the Mallet locomotives were no longer needed and came to the Selketalbahn . Two Mallet locomotives were scrapped: 99 5905 in 1975 and 99 5904 in 1990. The other three locomotives remained in existence.
99 5901 and 99 5903 were again painted in historical green with yellow decorations. They also received their historical numbers again: NWE 11 and NWE 13 II (before 1918 it was number 18). The 99 5901 has been painted black again since 1998. Locomotive 99 5902 last had the designation NWE 12 III (until 1927 number 14) at the NWE and has been on the road with green paintwork since 2007. After all deadlines for 99 5903 had expired, it was postponed from maintenance in 2000.
The current stock of vehicles on the Harz narrow-gauge railways :
- 99 5901: ready for use
- 99 5902: ready for use
- 99 5903: Deadline expired, in Wernigerode-Westentor.
A similar locomotive is the 99 5906 built by the Maschinenbau-Gesellschaft Karlsruhe .
