A pink coal hopper? Yes, Union Electric Company/Ameren has UCEX No. 2014 painted pink to support breast cancer awareness in its coal-hauling fleet of hoppers. On July 3, 2016, “On Track for the Cure” No. 2014 sits at Bill, Wyoming, waiting for another load of Powder River Coal. In addition to the the pink ribbon, small lettering on the right side states that the special colors are “Sponsored by: Metro East Industries, William Hayward and Fast Signs-Milwaukee.” Just remember, the rotary coupler end is the pink end.
