Mr. Gow, just as you were answering Mr. Hubbard's question, you were cut off at the end because he was moving on to something. You indicated that derailments had been unusually high and that they were getting better, and then you started to say “but”. You didn't finish. I'm going to make the assumption that you were going to say that they were getting better but that they're not yet good enough. I don't know if I'm putting words in your mouth, but I'll let you put in your own words.
