* The [=AA20-1=], the sole non-articulated locomotive with seven driving axles (its Whyte notation -- or wheel configuration -- is 4-14-4) and built by the Soviet Union. An attempt to FollowTheLeader on locomotives with more than eight driving wheels (particularly the 4-12-2 design of the Union Pacific\'s 9000-series), the main differences were 1) having another driving axle and trailing axle and 2) being at the Russian gauge of 5\' as opposed to the standard 4\'8 1/2\

A poor wheelbase, with the axles too close together, doomed the locomotive to failure.
* The [[http://www.lner.info/locos/IC/kitson.shtml Kitson-Still steam/diesel hybrid]], proof that hybrids with steam are really bad. A few trials on the LNER was all it had before it was withdrawn and eventually scrapped.
* The 6-2-0 wheel arrangement, putting the weight on the three leading axles rather than on the driving axle. In Great Britain, only \\\'\\\'\\\'one\\\'\\\'\\\' locomotive of this wheel arrangement, the \\\'\\\'Liverpool\\\'\\\' of 1848, was built; and in the United States it fared no better, as many were rebuilt in the 4-4-0 wheel arrangement. Very few locomotives have more than four driving wheels, and no more would have six until the Pennsylvania Railroad introduced its S1 class in the late 30\\\'s.
