World's Longest, Heaviest Trains! 

The heaviest and longest trains in the world are in Australia's North-West Pilbara region. I shot these clips on Rio Tinto's rail line near Tom Price, Marandoo and Yandi iron ore mines while I was waiting to unload my truck. Locomotives are fully imported GEs made in the U.S., you won't see these locomotives anywhere else in Australia, or in many places outside of North America or Canada..
