A Schwartzkopff-Eckhardt II bogie (Schwartzkopff-Eckhardt-II-Lenkgestell or Schwartzkopff-Eckhardt-Gestell) is a mechanical device to improve the curve running of

steam locomotives A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomot ...

and the carrying axle are combined within the bogie. The carrying axle steers the second coupled axle via a long shaft and this also moves the first coupled axle via a Beugniot lever. This bogie is used on the DRG Class 84. Whether DR Class 99.23-24 locomotives were also fitted with this arrangement is not entirely clear. It was named after the L. Schwartzkopff locomotive factory and its chief engineer, Friedrich Wilhelm Eckhardt.
