COBI Steam locomotive Class 49C DOVREGUBBEN #1331

The Dover section of the Norwegian railway network was put into service in 1921. Due to the high gradient of the line, it was necessary to build more powerful locomotives exclusively for this line.

The design was commissioned to Thune's Mekaniske in 1933. This was an important investment for the region around Hamar, as the economic situation was not favourable and any work was very welcome.

The first three locomotives were delivered in 1935-1936 and almost immediately became very popular throughout Europe. 

The locomotives initially had many technical shortcomings and Norwegian Railways had to turn to the German manufacturer Krupp AG, who made several important improvements in the design.

The Norwegian company Thunes's Mekaniske was very concerned about the involvement of the German manufacturer. The government eventually commissioned the Norwegian company to produce two more units to prevent labour unrest. 

The locomotives carried freight exclusively on the Otto to Trondheim line, where they set many speed records.

A total of 7 units were built in the A-C series.

The last machine was taken out of service on 16 December 1958 with the arrival of diesel locomotives made in Sweden.
