journals on the outside of the wheels, but by cogwheels located in the centre of the axles. The axles are housed in the locomotive frame such that they are able to move at right angles to the axis of the rails to a certain degree, likewise the cogwheels are able to slide relative to one another. In this way curves can be negotiated with less friction being generated.

s of Class 87 were built with Luttermöller axles, front and rear. The 16 locomotives of this class were however retired as early as 1954, because they tended to overheat at higher speeds and could therefore only be used for shunting duties. A five-axled, , steam engine with the Luttermöller system was procured by the private South Harz Railway (''Südharz-Eisenbahn''; Braunlage - Walkenried - Tanne) in 1928 from Orenstein & Koppel with operating number 61. It proved itself so well on the winding route, that in 1930 two

Luttermöller axles found further use on narrow gauge lines, e.g. in Java (Indonesia).
