Lester is a wild and rambunctious old experimental tender engine who used to work in the wild west. Now he works on the main line pulling trains from Anderson City Central to Wheelerton and back, but occasionally pulls a mixed traffic train comprised of his very own sets of cars (carrying workmen and supplies) to various quarries and mines.

Lester is often described by the other engines as a wild and carefree spirit more times than they can count. In fact, this sort of a rebellious attitude coupled with the rough riding speed he's got can lead him off track if he's not careful......which can get him into serious trouble.

His voice should sound like Gilbert Gottfried.
