This photo was taken by a passenger. The truck hit the fourth car - the second passenger car following two engines.

Here's a good news aggregator that has a compilation of reports.

I see only two possibilities: 1) the driver fell asleep and it was fluke accident, or 2) the collision was intentional. You don't hit the fourth car back if you're just an idiot trying to beat the train.
