Geared steam locomotive
This gearing is part of the machinery within the locomotive and should not be confused with the pinion that propels a rack locomotive along the rack between the rails. The geared steam locomotives that have been built have been for conventional track, relying on the adhesion between wheels and rail.
Naming of British railway rolling stock
Since the invention of the very first railway steam locomotive in 1804, railway companies have applied names to their locomotives, carriages and multiple units. Numbers have usually been applied too, but not always; the Great Western Railway only applied names to its own broad gauge locomotives (though numbers were given to such locomotives that it inherited from elsewhere).
