Other equivalent classifications are:

UIC classification: 1CC1 (also known as German classification and Italian classification)

French classification: 130+031

Turkish classification: 34+34

Swiss classification: 3/4+3/4

The UIC classification is refined to (1'C)C1' for Mallet locomotives.

The 2-6-6-2 wheel arrangement also appeared in Soviet Russia as a standard gauge (5 foot gauge) locomotive built by Kolomna works. The P34 was a modern but compact Mallet. Only one was built, the next Mallet from the Kolomna works was a much larger machine the P38 2-8-8-4.
