The Norwegian steam locomotive series NHJ D was built between 1875 and 1892 and between 1896 and 1898 by Manning, Wardle and Co. in Hunslet , Leeds , West Yorkshire , England and Nylands mekaniske Verksted in Bjørvika ( Oslo ) for the Norsk Hoved-Jernbane . When the NHJ was taken over on March 4, 1926 as the Oslo district in the Norges Statsbaner (NSB), the state railway company in Norway, the locomotives came into their stock.

The series was a small and light locomotive with little pulling power. It was mainly used for subordinate trains and was later only kept as a reserve locomotive at larger stations.

Used by Norsk Hoved-Jernbane

As early as the mid-1860s, the NHJ and NSB were working closely together and sorting their standard gauge locomotives into a common numbering system. Therefore, when NSB took over the locomotives in 1926, no numbers had to be changed.

NHJ H "

Around 1900 NSB and NHJ started classifying their locomotives. NSB chose numbers, while NHJ chose letters to designate the series. In 1923 the existing series were reassigned. In this classification, the eight locomotives with a second occupation were given the series designation  H " . This designation was released from the three locomotives of the series NHJ H (1910) with a tender, which was acquired in 1910 , as it was given the new designation NHJ B" .

Used by Norges Statsbaner

When NSB took over the series in 1926, it was given the new name NSB 7a . Locomotive 62 was decommissioned on August 24, 1928 and scrapped in the same year.

While the locomotives remained with NSB in the Oslo district at the beginning of their service, they were later given to other districts:

  • No. 25 came to Kristiansand on June 24, 1941 and to Stavanger on June 25, 1946 . The return to Oslo took place on November 10, 1952.
  • No. 34 left Oslo on April 21, 1948 for Stavanger and returned on March 5, 1953.
  • No. 62 was delivered to Kristiansand on June 12, 1939, returned to Oslo on February 22, 1954, and left the district on June 3, 1955, heading for Drammen . There she was only used for a few days and returned to Oslo on September 13, 1955.

Six of the locomotives were in use at the end of their careers on the Bergen Railway . In the period between 1954 and 1964, they were decommissioned and some of them were scrapped.

Existing locomotives

No. 11, which was the last locomotive to retire from service on August 20, 1964, has been preserved as a museum locomotive on the Krøderbane . In addition, No. 25, which was decommissioned on April 18, 1955, exists in the Norsk Jernbane Museum in Hamar .
