Littera F was a class of electric locomotives operated by the Swedish state railways (SJ) between 1942 and 1983. Twenty-four F-locomotives were constructed and delivered between 1942 and 1949. The design was a rigid-framed locomotive with quill drive and the axle arrangement 1′Do1′, inspired by the German type E 18. The F-locomotives pulled express passenger trains and express freight trains.
