Up to the end of the war in 1945 , the Schichau-Werke had supplied about 4,300 locomotives of several classes to customers that included the Deutsche Reichsbahn and GEDOB formed from disbanded Polish State Railways . These included the DRG and DRB standard steam locomotive ( '' Einheitsdampflokomotive '' ) classes 23 , 41 , and DRB Class 52 Kriegslokomotive . as well as DRG Class 86 . The Schichau-Werke also designed the Class 24 and delivered its first two orders . After the war , the shipyards were acquired by Poland – to which the region was assigned by border changes promulgated at the Potsdam Conference . Postwar production included ships , railcars and boilers . The Schichau shipyard at Danzig was subsumed into the Lenin shipyard in 1950 and , in 1980 , attracted worldwide media coverage as a result of protests led by the Solidarność trade union
