Thank you, Mr. Chair.
I want to go back a little bit to what I was talking about earlier, the machines versus the inspector—not “versus”; I guess they would be complementary to each other. These machines, I understand, detect cars, check the level of surface, check elevation, check whether there's any consistency or inconsistency in the track. Do they also have memory of going over certain tracks, to see whether the track has changed dramatically from the previous inspection four months before? Or is that not part of the deal?
