Follow a breakdown crew as they tear apart a 50-year-old locomotive and rebuild it from the frame up, using the latest energy-efficient technology. This four-axle train must boast 1,400 horsepower and ride the rails for another 50 years. Chains and cranes do the heavy lifting, as power tools crank, torches flare and fires blaze. In just eight weeks, this loco will undergo a complete transformation and emerge again as a lean, green pulling machine.
