The Norwegian series NHJ A was the name for the first steam locomotive series in Norway. It was built between 1851 and 1870 with a total of nine copies by Robert Stephenson in Newcastle upon Tyne , England , for the Norsk Hoved-Jernbane .
The series was called long boilere because the boiler extended the entire length of the locomotive. The front barrel axis was firmly fixed in the frame . The locomotives were originally equipped with a small windbreak in front of the driver's seat. Later they were given a cab, but without a rear wall, so that the stoker could shovel the coals from the tender into the fire box .
history
The first three locomotives (1-3) were delivered in autumn 1851 and could be used as construction locomotives for the Hovedbane . Nos. 4 and 5 were delivered on November 20, 1852 and July 26, 1853, respectively, and were put into operation with the opening of the line on September 1, 1854. No 11 and 12 were delivered until June 27, 1861.
NHJ A 1
The last locomotives in this series followed on June 8, 1870, the numbers 22 and 23, designated as A 1 .
NHJ J
When the company's new series overview was introduced in 1900, the machines were actually assigned to the new NHJ J series . The locomotives of the NHJ B series have also been sorted into this new series . A redesignation did not take place, during their operating time the locomotives only had the number designations 1 to 5, 11, 12, 22 and 23.
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, nos. 22 and 23 were still available, but were not taken over into the NSB's portfolio.
Remained
The first locomotive to be eliminated was No. 11, which was decommissioned after a boiler explosion on December 22, 1891 at Strømmen station . Then on April 1, 1906, the No. 3 followed and in 1911 No. 1, 2, 4 and 5. The use of No. 12 ended in 1919, that of No. 23 on July 27, 1926. The last machine was No. 22, which on the day of its separation on November 18, 1927, had belonged to the NSB for well over a year. All locomotives were scrapped.
