We have on-board video and voice recorders, following signal indications, and passenger trains colliding with vehicles in our high-speed train corridor. The first two of those issues are squarely coming out of our Burlington investigation, and they are both outstanding recommendations. As for the third, we see an awful lot of collisions in the high-speed corridor at rail crossings, and that's why that's on the list. These really are the issues where we verified and have done an awful lot of analysis to determine that they are the most important issues, and they're the issues that we really want to see action on.
