Rail rates are generally set by the railways. They are published in a tariff. At the same time, very often there are confidential contracts where a shipper and a railway will negotiate a rate that is different from the rate in the tariff.
In the grain sector—and this is the only sector where it applies—there is a revenue cap on the total revenues the railways can earn from the movement of grain in a calendar year. There's a formula under the act to determine that amount, and that of course varies. There are certain factors where it can change year over year related to the volume. There is an inflation factor that is considered. So there is a revenue cap for the grain sector.
In general terms, when shippers do not like the rate they are paying for rail service, they do have access to a final arbitration provision under the act, and that is different, and will remain different, from the new provision on service agreements.
