The Engerth locomotive was a type of early articulated steam locomotive designed by Wilhelm Freiherr von Engerth[1] for use on the Semmering Railway in Austria. The distinctive feature of the Engerth design was an articulated tender as part of the main locomotive frame. Some of the weight of the tender therefore rested on the driving wheels, improving adhesion, while articulation allowed the locomotive to navigate the narrow curves of mountain railways.
