An Tai Bao 3, one of three former Conrail (nee Erie Lackawanna) U33C's after recently being rebuilt. The An tai bao surface mine is a joint venture with the Chinese government These U-boats retain their low noses but the cab is removed in favor of remote control equipment while an 1800 hp Cummins engine replaces the original FDL, both features common to the mines existing dump truck fleet. These rebuilt units are reportedly the last U33C's in existence as of 2005.
