0-10-2
*** Shopping-Tip: 0-10-2
An '''0-10-2''', in the
Whyte notation for the classification of
steam locomotives by
wheel arrangement, is a locomotive with no
leading wheels at all, ten
driving wheels, and a two-wheel
trailing truck.
The equivalent
UIC classification is '''E1''''.
United States
In the US, this type is known as the '''Union''' after the first and only US
railroad to purchase locomotives of this arrangement, the
Union Railroad (Pittsburgh, Pennsylvania) Union Railroad in the
Pittsburgh, Pennsylvania area.
The Union Railroad was a switching and transfer line owned by
U.S. Steel, serving a number of plants in the area and connecting with six trunk line railroads. Operation was only at low speed, thus a leading truck's stability was not required. The intent was to eliminate helper requirements on grades, and thus a locomotive larger than the Union's previous
switchers and
2-8-0 "Consolidations" was needed. Ten driving wheels allowed the application of sufficient
tractive effort within the
axle load limits of the line, and the requirement for a large
firebox and plentiful steam-raising ability necessitated the trailing truck. To increase tractive effort still further, a
booster engine was fitted to the leading
tender (locomotive) tender truck.
Ten of these locomotives were built by the
Baldwin Locomotive Works for the Union Railroad between
1936 and
1939.
Upon
dieselization of the Union in
1949, the locomotives were sold to fellow U.S. Steel railroad the
Duluth, Missabe & Iron Range, where they served until
1962. One of these locomotives survives as a static exhibit at
Greenville, Pennsylvania.

Europe
In
Germany, a number of
narrow gauge tank locomotives were built with an 0-10-2 configuration. All used some form of articulated drive that allowed the outer driving axles to move sideways or radially to negotiate curves. An example was a group of locomotives built for the narrow gauge lines of
Bosnia (region) Bosnia that utilised the
Klose locomotive Klose System for an articulated drive.
