With the introduction of a series plan in 1900 at Norsk Hoved-Jernbane , nine steam locomotives, previously only numbered, were included in the Norwegian NHJ B series . These locomotives had the wheel arrangement and were 1'B with a two-axle or a three-axis either Tender coupled.
Modifications no. 8–10, series B and B 1
The three locomotives No. 8-10 were essentially conversions that arose between 1890 and 1893 from the three B-coupled freight train tender locomotives with these numbers delivered by Robert Stephenson on June 11, 1857 . Probably only the frame and the drive wheels from the original locomotives were used, so that they are actually new buildings that were built in the company's main workshop at Oslogate 3 in Kristiania under the direction of foreman Ole Adamsen. The two-axle tenders for No. 8 and 10 came from older locomotives, probably from No. 7, which was retired in 1884, and No. 6, which was decommissioned in 1888, and which also came from Stephenson and were converted from tank locomotives to locomotives with tender as early as 1864/65.
The three-axle tender of No. 9 came from locomotive No. 11, which corresponds to the NHJ A series introduced in 1900 . However, this was taken out of service after a boiler explosion on December 22, 1891 in Strømmen station . This made the tender free. Locomotive no. 9, also from Stephenson and converted from a tank locomotive into a tender locomotive in 1863, received a new boiler, an Adam axle was installed and the original Stephenson control was replaced by an Adam slide control .
In 1900 these three locomotives were given the series designation B , with No. 9 being grouped into subgroup B 1 due to the other tender .
New build No. 6 "-7", 85-88, series B 2
The retrofitting of No. 9 was seen as very successful because it enabled the locomotive to be used for all types of trains. The design meant that six new locomotives in this version were ordered from foreign locomotive manufacturers.
The new buildings were assigned to the B 2 series and were sold by Hanomag , No. 6 "and 7", 1893, Nydqvist och Holm , No. 85 and 86, 1896 and the Swiss Locomotive and Machine Factory , No. 87 and 88, 1898, delivered.
Use at NHJ
Much larger locomotives were procured for the Hovedbane around 1910 in order to cope with the increasing train weights and the increasing number of trains to be carried. Therefore, the series B , B 1 and B 2 were assigned lower-level tasks. These were shunting services, special trains between Lillestrøm and Strømmen and local trains between Lillestrøm and Jessheim .
NHJ J
In 1923 the series at NHJ was reorganized. All locomotives of the series NHY B , NHY B 1 and NHY B 2 were in NHY J renamed. The series designation was not written.
Use at NSB
When NHJ was taken over on March 4, 1926 as Oslo district in the Norges Statsbaner (NSB), the state railway company in Norway, numbers 6 ", 7", 9, 87 and 88 were still available, but were not in the Stock of NSB taken over. The last machines were No. 6 "and 9, which had belonged to NSB for well over a year on the day they were retired on November 18, 1927. All locomotives were scrapped.
