0-8-2
*** Shopping-Tip: 0-8-2
An
0-8-2, in the
Whyte notation for the classification of
steam locomotives by
wheel arrangement, is a locomotive with no
leading wheels, eight
driving wheels (4 axles) fixed in a rigid frame, and two
trailing wheels (normally mounted in a
trailing truck).
The equivalent
UIC classification is
D1'.
The 0-8-2 was not a common wheel arrangement. In
North America, its use was confined to
2-8-2 "Mikado" types assigned to
switcher roles; the lead truck was often removed to give more weight on drivers, a guiding truck not being needed at slow speed.
In the
United Kingdom, a number of
tank locomotive designs were built of the 0-8-4 type, including the
London and North Eastern Railway (LNER)
R1 class, designed by
Henry A. Ivatt and built originally for the
Great Northern Railway (Great Britain)|Great Northern Railway as their class L1. These locomotives were intended for suburban passenger service, but did not prove satisfactory, so they ended up on freight service.
The 0-8-2 arrangement proved a little more popular on
narrow gauge lines, where (due to slow operating speeds) its lack of leading wheels was less important. 0-8-2 locomotives operate, for example, on the Zillertalbahn in
Austria, and on the
Ravenglass and Eskdale Railway, a
miniature railway in
England's
Lake District.
