Stortyskarna
The passenger train locomotives number 27–29 of Stockholm–Roslagens Järnvägar, usually referred to as stortyskarna (literally "the Great Germans"), were the largest steam locomotives ever built for the Swedish three foot gauge railways. Initially used in fast passenger trains from Stockholm to Rimbo and Hallstavik, they were moved to freight service after the Stockholm–Rimbo Line was electrified in 1946.
