Sweden's first steam locomotive, dubbed "Förstlingen" ("First born"), was delivered to a mine railway in 1853. Because of its sharp bends and gradients, the track was not particularly suited to locomotives. (The locals called it "the pig" because of the way it grunted uphill and squealed against the rails on the bends.)
Even though it wasn't an instant success, the locomotive paved the way for future development and eventually made Munktell's a leading manufacturer of not only steam locomotives but also steam engines in general as well as locomobiles and traction engines.
