The Norwegian steam locomotive series NSB Type 24 was built between 1909 and 1921 by Thunes mekaniske , Nydqvist och Holm and Hamar Jernstøberi ( German iron foundry Hamar ) for the Norges Statsbaner (NSB), the state railway company in Norway. As a further development of the NSB Type 22, the series was largely identical to this.
history
The locomotives were typical freight locomotives with large steam boilers and large cylinders, but small driving wheels, so that they had great pulling power but a low top speed.
NSB type 24a
The 24a was a further development of the 22a and was delivered as a wet steam composite locomotive without superheater with a twin engine.
No. 147, 194–196 and 210 were delivered as 24a . 147 was built in 1909 by Thunes mekaniske for Nordbanen . With the exception of the modified driver's cab, the locomotive exactly corresponded to 22a 144 . No. 194, 195, 196 and 210 were built by Hamar Jernstøberi in 1909 .
NSB type 24b
Thunes mekaniske Verksted delivered the first superheated steam locomotive of the 24b series in 1910 . After delivery of this design, it was decided to convert all older locomotives of the types 22a and 24a in this way. The rebuilding of the 24a lasted from 1938 to 1949. Thereafter, twelve locomotives were available in this design.
NSB type 24c
This sub-series was delivered in three copies by Nydqvist och Holm in 1921 and was equipped with a feed water preheater.
NSB type 24d
In 1924 an attempt was made with a superheated steam locomotive. For this purpose, the 24a 147 , the first locomotive in the series, was converted accordingly in December. The locomotive remained a one-off, the compound drive was removed again in November 1941 and the locomotive was added to the class 24b .
NSB Type 24e
Another renovation from NSB 24b , in which the heating area was to be increased from 108.3 m 2 to 112.1 m 2 and the superheater area from 36.3 m 2 to 42 m 2 , was not carried out. The series designation NSB 24e was already provided for this variant .
Use and whereabouts
After the Second World War , the locomotives were mainly used on the Solørbane , until 1956 on the Sørlandsbane between Sira and Stavanger , until 1959 on the Randsfjordbane and until 1968 on the Valdresbane .
24b 147 derailed on February 6, 1967 between Leira and Aurdal near Nordåkjordet and was dismantled on site. It was the last locomotive to be used on the Valdresbane. 24b 195 , 210 and 264 were retired on May 10, 1968 after their use on the Randsfjordbane and the Valdresbane.
The last locomotive in service was 24b 236 , which was retired on October 22, 1970. It was preserved.
Museum locomotive 24b 236
The locomotive was built on June 29, 1912 for the Gjøvikbane by Thunes mekaniske. Later it was also used on other routes in the Oslo district and in the Drammen district . It was decided to retire in 1958, but after an accident involving the 24c 404 , it was put back into operation on February 6, 1959. In the mid-1960s, the machine was largely in use on the Valdresbane, where it carried both freight and passenger trains. At the end of their period of service in 1968, the 236 was stationed again in Drammen, where her service with NSB to carry the gravel trains from pukkverk vein ( German quarry vein ) to the station Kongsberg ended.
It was taken out of service on October 22, 1970, the following year an agreement between Norsk Jernbaneklubb (NJK), the Norsk Jernbane Museum in Hamar and NSB decided to preserve the locomotive for posterity. After the agreement was signed, the locomotive was parked in Kløftefoss on the Krøderbane . In 1978 the operational refurbishment took place in Stavanger in order to use it for the 100th anniversary of the Jærbane . After the event, it was used on the Krøderbane, where it was the only operational standard-gauge steam locomotive in Norway between 1978 and 1981. It was often used for film and television recordings and other rail-related events until a second steam locomotive of the NJK was restored and made roadworthy.
