That's terrific. Thank you.
Ms. Hardy, you mentioned the distributed power solution. Something we talked about last year was about cold temperatures and how you get the pneumatics working on the brakes, putting mid-train power sources.... Is that a new system you're doing? Is it something that both rail lines are doing? Could you comment on if we get hit by another severe temperature in January or February...? Is that something new that you're going to be implementing this year?
