Thanks, Mr. Chair.
Thanks to the witnesses here for the reports you've given and the time you've taken to inform us individually on some of your issues.
I want to go after the rail crossing issue first because it's one that I feel is very much not represented in this bill, much as you think. First of all, I want to talk to you about the statistics you presented here. There was a fairly significant downturn in the number of crossing collisions, say, between 1992 and through that decade of the 1990s. We saw a pretty steep downturn. Could you tell me how that was accomplished? How did that come about?
