2-12-0

From Wikipedia, the free encyclopedia

In Whyte notation for the classification of steam locomotives by wheel arrangement, a 2-12-0 is a locomotive with one pair of unpowered leading wheels, followed by six pairs of powered driving wheels, and no trailing wheels.

The equivalent UIC classification is 1' F.

[edit] Germany

Whereas standard German freight train steam locomotives were 2-10-0 types, between 1917 and 1924 the Esslingen locomotive works produced 44 units of the so-called class K (later renumbered to class 59). With a top speed of only 60 km/h these locomotives were designed for heavy duty in mountainous areas such as the 'Geislinger Steige', with special attention on low load per axle (16 t). After electrification of that line the units were used on the 'Semmeringbahn' in Austria. The last four units were in service until 1957.
