The German Class 87 was a standard (see Einheitsdampflokomotive)
goods traintank locomotive with the
Deutsche Reichsbahn-Gesellschaft (DRG). It was specifically designed by the firm of
Orenstein & Koppel for use in
Hamburg Harbour. The harbour lines had minimal curve radii of only 100 metres (330 ft) and high train loads to be moved. The
axle load had to be no more than 17.5 tonnes (17.2 long tons; 19.3 short tons). These requirements resulted in an axle count of five axles. In order to keep wear and tear on the running gear within acceptable limits only the middle three
wheelsets were linked by
coupling rods, the two
Luttermöller outside axles were driven by cogs.
Due to damage the vehicles were partly also operated as 1′D, D1′ or 1′C1′ engines.
From 1951 they were superseded by
DB Class 82 locomotives.
