It's hard to tell. 1. I can't find the 11.3 billion statistic on the Wikipedia page. 2. The stats seem to be per vehicle mile. An average train carries maybe 100 times as many people as a car. If the people on the train were driving cars there'd be 100 times more vehicle miles. 3. Are people who commit suicide by jumping in front of a train counted in the statistics? It seems that if there were no trains, some of those people would find an alternative, so it might be unfair to include them.
