Each item on the watch-list is supported by our investigations' outstanding recommendations. Since we initiated the watch-list in 2010, a number of issues in rail, in marine, and in air have been removed from the watch-list as action has been taken. Other new issues have emerged and have been added, so we currently have three issues in air, one in marine, four in rail, and then two multimodal issues that we are working on.
