 The ten-coupled Class 180, whose first, third and fifth axles were able to slide sideways in the frame, demonstrated that, in almost all cases, locomotives with multi-part frames and complicated articulated designs would be superfluous.From that time forward this type of construction became the standard for heavy goods locomotives.From 1893 to 1916, Karl Gölsdorf was the chief design engineer of the Imperial Royal Austrian State Railways ("kaiserlich-königlichen österreichischen Staatsbahnen" or "kkStB") and developed 25 different classes of steam locomotive (in 47 variants) during his career.
