'Feather II' was a British operation by the Special Operations Executive to complete the work of 'Feather I' by destroying the last electric locomotive operating on the railway line between Orkanger and Thamshavn (April/May 1944).

The Norwegian party (A. Hægstad, T. Bjørnaas and A. Wisløff) was delivered to Stockholm in neutral Sweden and then entered Norway from Sweden on 21 April. On 9 May the men blew up the locomotive and on 1 June also destroyed the line’s rail car. One of the locomotives had been sent to Oslo for repairs, but on 13 September this was attacked and further damaged by the SOE detachment in that city.
