That was more weight but on rails with steel wheels. Technically a 4400 hp locomotive can pull even up hills a 34 million pound train, meaning a 1/34th train only needs about 130 hp. Personally think this is the coolest gimmick of all time. Dirt road, on tires, and this thing probably has less than 250 hp to the wheels for about 1/2 a million pounds.
