Mr. Chair, the approach that we are taking with respect to responding to the Transportation Safety Board is to deal with a means of containment, meaning the DOT-111 cars. We have done it in two ways. First, he should know that there are a variety of different types of cars within this framework of DOT-111. Some of them, like the 5,000 that we want out of the country in 30 days, are the ones that are the most dangerous. There is a version of DOT-111 cars in various inclinations in between. That is acceptable.
We published that regulatory Gazette process in January of this year. That is standard. What we would like is to have cars at that standard or higher by May 1, 2017. That is what we will be doing over the next three years.
