Can I add something here about training? I'm not quite sure about the SMS system. I'm just coming from design and manufacturing. From day one, when we look at the tank car business the first thing we had to do was everybody—not design engineers, not manufacturers—everybody in our company for whom there was a chance they would go close to the tank cars we are building, touch them or see them, had to go to a very specific training called haz-mat. Everybody goes through that haz-mat training and we went through it. There is a test, and you have to write the test and you have to pass. Every one of us on our hardhat has a sticker, a big red sticker, that says this guy has been through the training and has passed the test. That haz-mat training talks about tank cars, it talks about safety, it talks about different commodities, and there are different signs.
When we finish the tank car we put a stencil on it. It tells what this tank car is, the capacity, who built it, when it was built, when was the last time it was inspected, what type of valves are on it, what type of brakes. Everything is on the tank car. He is the expert of stencilling the car. There is another section with signs. So if somebody doesn't know how to read, there is a sign that shows what category of products this tank can move. So in the training for us, for designers and manufacturers, we cannot touch even a piece of tank car without passing the haz-mat test. And the haz-mat has different training levels for different categories.
