The Chicago & North Western Railway converted two 2-10-2
locomotives formerly owned by subsidiary Chicago, St. Paul, Minneapolis & Omaha into 0-10-2 locomotives in 1944.
They were classified J-1 both before and after conversion. One was scrapped in 1950 and the other in 1953.
, 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
that utilised the Klose System
for an articulated drive.

In the Turkish classification system for railway locomotives, the number of powered axles are followed by the total number of axles. It is identical to the Swiss system except that the latter places a slash between the two numbers.Thus0-6-0 becomes 33...
