With respect to the ratio, I can't in fact answer that. That's a heck of a big difference.
All I can say is that it would have to do with the safety standards applicable, the maintenance standards, the track deterioration.... Not just from my own perspective but from what our colleagues tell us at work, I believe the road bed is deteriorating. Although they seem to spend money on the infrastructure with rail programs, I don't know if a lot of that is fixed to the standards we now have, because they fix them to a minimum standard today. But tomorrow that standard could change; it could be below the minimum standard, whereas at one time in Canada we had very high standards.
That's really unfair to say, because the density of traffic we currently have over those rail lines has probably increased by 15%—
