Karl F. Nystrom
Karl Fritjof Nystrom was an American rail engineer who introduced a number of important innovations, including welded lightweight freight and passenger railcars. He is probably best known for his work designing and building the Hiawatha trains for the Milwaukee Road.
==Early Career==
Karl Fritjof Nystrom was born in Asba Bruk, Sweden in 1881. He graduated in 1904 as a mechanical engineer from the Mining School at Filipstad, Sweden. To pay for his education he worked summer jobs in machine shops in Stockholm and in steel mills in other parts of the country. Following graduation he went to Germany to study high tensile steel, but before finishing his studies he decided to seek employment in Pittsburgh, the center of the US steel industry. He worked as a ‘blueprint boy’ and then as an engineer at the Midland Steel Company, before obtaining employment for Pressed Steel Car Company as a draftsman.
His work at Pressed Steel Car apparently caused Nystrom to decide to focus his career on railcar design and manufacture. It appears that he may have decided to leave Pressed Steel during the Pressed Steel Car strike of 1909, because he joined Pullman in the later part of that year, where he was co-designer of the fist steel sleeping car. He also established the specifications for the first all-steel railway post office car.
He moved through a fairly rapid succession of railcar jobs, working for the Southern Pacific during the electrification of its Oakland-Alameda line, where he designed and built their first electric interurban cars, for the American Car & Foundry Company, for the Acme Supply Company, for the Grand Trunk (the Canadian National) and for the Canadian Pacific.
