The Norwegian steam locomotive series DIOC A1 and A2 was built in 1902 as a saddle tank locomotive by Robert Stephenson in Newcastle upon Tyne , England with the serial numbers 3004 and 3005 for the Dunderland Iron Ore Company (DIOC) and the Dunderlandsbanen it operates .
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 two locomotives DIOC A1 and A2 were assigned to the NSB Type 53a series . Locomotive 53a 491 (the original DIOC A2 ) was the last of the series to be decommissioned and scrapped on November 7, 1955.
