The Norwegian steam locomotive series DIOC B1 to B4 was sold in 1905 by Thunes mekaniske in Christiania (B1, B2) and with the serial numbers 13 and 14 by Hamar Jernstøberi (B3, B4) in Hamar for the Dunderland Iron Ore Company (DIOC) and her operated Dunderlandsbanen .
When the Dunderlandsbane was officially taken over by the Norges Statsbaner (NSB), the state railway company in Norway, on June 1, 1947 , the locomotives were included in their stock.
Use at Dunderlandsbanen
The DIOC operated an island network from its ore mines in the Rana area to the port of Gullsmedvik near Mo i Rana as early as 1902 . With the construction of the Nordlandsbane in 1942, the Dunderlandsbane was connected to the NSB network. The Dunderlandsbane railway line was integrated into the Nordlandsbane.
Used by Norges Statsbaner
The takeover of the Dunderlandsbane by NSB took place officially on June 1, 1947. On April 27, 1948, the locomotives of the Dunderlandsbane were integrated into the NSB's numbering plan. The four DIOC B1 to B4 locomotives were assigned to the NSB Type 56a series . Locomotive 56a 496 (the original DIOC B4 ) was the last of the series to be decommissioned and scrapped on May 11, 1955.
