 Thank you for the question. As you noted, this is a central focus for us. We sought to do everything that we can do short of an act of Congress in order to enhance rail safety. Two recent measures I would point to that we think are particularly important is our rule on minimum crew size. Most Americans would probably be shocked to discover that until we acted, there was no rule saying that you had to have more than one person even on a two-mile-long train.
