The German '''Class 87''' was a standard (see ''[[Einheitsdampflokomotive]]'') [[goods train]] [[tank 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 {{convert|100|m|ft}} and high train loads to be moved. The [[axle load]] had to be no more than {{convert|17.5|t}}. 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 [[Wheelset (rail)|wheelsets]] were linked by [[coupling rods]], the two [[Luttermöller axle|Luttermöller]] outside axles were driven by cogs.<br />
<br />
Due to damage the vehicles were partly also operated as 1′D, D1′ or 1′C1′ engines.<br />
<br />
From 1951 they were superseded by [[DB Class 82]] locomotives.<br />
