Pure destruction. Top Gear wanted to see exactly what happens when a train smashes into a car stuck on the railroad tracks so they set up a test of their own: they put a minivan on the tracks and pummeled it with a speeding train. It gets pretty brutal.
The train was going 78mph before it obliterated the minivan and pushed the car impressively far away before the train stopped. The minivan that Top Gear smashed looks barely recognizable after.
