I think we're clear on the tank cars. We accept what the government has said. We support the changes that we think have to happen in the industry and the type of car that has to be built.
The 1232 car is safer than the DOT-111 car. Is it as safe as the new car that is going to be put in place? No. The reinforcement, the steel, the bottom outlet valves, the top valves, the end caps, the amount of insulation in there, the amount of heat it can take, we're on record saying that's what we want and it's important for us to do that.
We have performed risk assessments. We've decided we are going to include the speed of not just crude trains, because people want it to go only on crude trains, but any train that carries more than what the key train facility is and the number of cars. We're slowing them down and they are going into census metropolitan areas at 35 mph.
We already have a PIH/TIH restriction at 35, at gateways, and we've included any dangerous goods at that speed. We do our own risk assessments to take a look and make sure that we're smart about what we're doing.
