2-10-10-10-10-10-2

Under the Whyte notation for the classification of steam locomotives, a 2-10-10-10-10-10-2 has two leading wheels, five sets of ten driving wheels, and two trailing wheels. Because of its length, such a locomotive must be an articulated locomotive. It is not longer than a normal articulated; the fourth and fifth sets of drivers are located under the tender.

The equivalent UIC classification is to be refined to (1'E)EEE(E1').

History

The Baldwin Locomotive Company may have developed a design for a 2-10-10-10-10-10-2 quintuplex; a drawing of this proposal appeared in Trains magazine. It was shown to be the largest and most powerful steam locomotive in the world. [1][2][3]
