Following from Wade's comment, as the railways mentioned when they responded to that, confidential contracts are in place between individual railway companies and individual shippers. Because the contracts are confidential, nobody knows the terms and conditions.
I think, generally, it's known that in some instances there are some performance guarantees by the railways, and these might be things like a unit coal train undertaking to deliver so many tonnes per week or whatever.
But my members in the Canadian Industrial Transportation Association tell me--and our membership is varied, as we have retailers, coal companies, manufacturers, a very wide range of members--the railways are going away from confidential contracts and going back to tariff pricing. So I suspect that in almost every case there are no real performance guarantees that would put the railways in a position where they would have to pay a financial penalty for service failures, which of course is not the case when the shoe's on the other foot. If the shipper keeps a car longer, they pay demurrage.
If I can take just a minute, Mr. Chairman, I would go back to a question Mr. Laframboise asked about some of these charges.
CN's tariff 9000 is a chargeable service tariff, and I suspect that's probably where demurrage is and that sort of thing, but they have others: terminal switching services, automotive services, dimensional services, unit train services, fuel surcharge tariff on bulk and carload services, fuel surcharge tariff on intermodal traffic, currency exchange surcharge tariff, movement of private cars in Canada and in the U.S., bill of lading charges. So even to submit a bill of lading, if you do it electronically, you don't pay. If you do it by paper, you have to pay something extra for it. Miscellaneous service charges, toxic inhalation hazard charges, and dray and trucking charges--those are all from CN.
Here's the CP list. Tariff 6666 is supplemental carload services tariffs comparable to the first in demurrage and so on: fuel surcharge tariff, U.S. switching tariff, currency exchange tariff, rules and regulations on international import-export traffic, and rules and regulations on domestic and intermodal traffic.
Those are some of the tariffs CN and CP have on various charges they impose on shippers over and above the quite legitimate freight rate for movement of traffic.
