According to information we got from the FRA and the AAR, without the Chatsworth accident, the one that triggered PTC in the States, they figured there have been two accidents in 20 years where there have been multiple fatalities that would have been PTC preventable. The argument they're making is that if you used that $13 billion and put it into improving crossings, you would save many lives every year. But would they do it? That's a different thing.
