I guess the way I would answer that is by saying that, for the most part, the railways operate on profit and loss, on a return on investment to their shareholders. When they look at the traffic that is generated on some of these rail lines, they have to have a very high volume, be it in bushels or cars, moving on that track. When that gets down to what they call a breaking point, then they feel it is time for them to discontinue service on those lines. So that's what they do.
In western Canada we're caught up in a chicken-and-egg scenario. The railway will provide service to the grain industry but the grain industry may not call for cars on those lines. So the railway will say that the grain companies aren't asking for cars, and the grain companies will say that the railway isn't providing good service.
