Derailments are Amtrak's most common kind of accident, but not the deadliest.
Derailments happen most often on the heavily traveled routes near major cities, especially in the Northeast Corridor. But they cause relatively few deaths — only six since 2000 before Tuesday's crash in Philadelphia. Maps shows the location of 447 major Amtrak derailments.
Trains are more likely to hit cars and trucks away from the large cities, where tracks are usually isolated from traffic. In rural areas, train-crossing collisions claim many more lives. Maps shows the location of 376 train-auto crashes. Older accidents lack detailed location data.
