We're still trying to get a hard number on the number of DOT-111s our industry has. We're roughly estimating it at about 10,000 cars. Many of those cars are not in TDG service. They haul non-TDG goods, and I think that's an important distinction.
Our member companies do use DOT-111s for some TDG movements that I've mentioned before—sulphuric acid, caustic potash, etc. We are at the point of asking Transport Canada to confirm their assessment of the capacity of the railcar maintenance system to move that hundred or so thousand DOT-111s that need to be retrofitted, as well as doing ongoing maintenance on the other cars in the fleet.
