Actually, top-fuel dragsters are approaching these speeds, albeit in just a quarter mile, and various Land Speed Record streamliners have hit speeds in excess of 400 mph, but seeing something this huge hustling along the French countryside is breathtaking. This specially equipped TGV was pulling three double-decker cars and had larger diameter wheels fitted, plus it had a boosted engine and increased voltage in the overhead lines. But even the regular TGV motors along at around 300 km/h on a typical run. High speed trains are increasingly being pitched to markets as varied as China and California, so these tests serve not only to draw attention to this mode of transportation, but to test updates in track and engine configurations. The full video of the record run is after the jump.
