Hi, I'm back.
To continue on with what we were talking about before on the lead locomotives—and this goes back to Mr. Jang—sometimes an engine is running long hood forward or another configuration where the lead engine is not looking forward the way you'd expect it to. Going back to what I asked in the first round, would you personally expect locomotives to be pointing both ways with the cameras front and back? Would the camera always be operating, or would it be manually set, or as soon as you put the reverser in, it's running? How do you see that?
