BHP Billiton (BHP Iron Ore) in the arid Pilbara region in Western Australia ordered GE AC6000CW & EMD SD70ACe with snow plows on both ends. A really hot place that might never see snow still has locomotives with 2 snowplows. Maybe they are used to push feral camels away.
Here are some images I found online of these BHP locomotives.
These are just my opinion.
