With respect to rail accidents, in 2015, 34% involved freight trains, 5% involved passenger trains, and roughly 62%, the remainder, involved accidents on non-main tracks, primarily yards and switching areas. Again, I can't give you a simple answer to the question. There are certainly lots of freight trains, so you'd have to compare the volume of freight trains travelling across the country against the number of passenger trains. That would have an impact on those situations.
