There are already requirements for train securement. In the emergency directive and the then-following rule that came into place in terms of train securement, there were requirements for how trains needed to be left secure so that they were protected from trespassing and other risks as well as runaway trains and other types of dangers. Those are addressed in the regulations, or the rules in this particular case. There is also a focus put on by our inspectors in those areas, as well.
In terms of blocking areas, there are also requirements in our regular operating rules as to what can be done in that regard. Again, if there is a complaint about a particular area, then our inspectors typically get involved with the community.
