 In addition to the construction of new locomotives, the general inspection of "ÖStB" locomotives was the main task of the factory due to the destruction of the neighbouring main repair shop at Floridsdorf.In 1946 the Soviet occupying forces placed the management of the Lokomotivfabrik Floridsdorf under the "USIA" - an organisation that managed 'Soviet property' in Austria.At the same time the factory was to be transferred to the ownership of the Austrian Republic under the nationalisation law passed on 26 July 1946.
