BHP Iron Ore set the longest train record between the Yandi mine and Port Hedland in Western Australia in 2011. The train was 4.53 miles (7.29 km) long and carried 82,000 metric tons or about 181 million pounds of iron ore. This is about the same weight as 402 Statues of Liberty (the Statue of Liberty weighs approximately 450,000 pounds).
The train had 682 cars that were driven by eight General Electric diesel locomotives. The total gross weight for the entire train was 99,734 metric tons (219.8 million pounds). This also beat the record for the world’s heaviest train, which was also held by BHP.
The locomotives were spread out among the cars in three pairs, along with two single locomotives. The entire train was driven 170 miles (273.6 km) by a single driver, and the trip took ten hours and four minutes. You can see the whole train below.
