We always try to learn from other industries, but there is a difference between us and the airline industry. We truly are 24-7.
Somebody might say, “Listen, planes run all the time”, but a lot of planes, and people, reset in the evening or late at night. With the railroad, it doesn't matter whether it's two o'clock in the morning or two o'clock in the afternoon, it's the same thing.
Do we analyze what other groups are doing? Absolutely. I think our record also shows how safe the railroad industry is and how much better we're getting all the time. If there's something we're missing, we'd love to try anything that makes sense in the operating environment we're in. We don't look exclusively at just what the railroads are doing.
