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. The Schwartzkopff-Eckhardt II bogie is a further refinement of the Krauss-Helmholtz bogie, whereby two coupled axles 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. == References == *Friedrich Wilhelm Eckhardt: ''Das Fahrgestell der Dampflokomotiven'', Transpress, Berlin 1960 *Friedrich Wilhelm Eckhardt: ''Lokomotivkunde.
