I'm not sure, sir, that I would say there are specific obstacles. I think what has happened over time is that the country has grown topsy-turvy. We all know about urban sprawl and all that sort of thing. There's been any number of other issues that have occupied peoples' minds. This thing has just grown up over the years.
In the old days, it wasn't a big issue if a farmer wanted to put a crossing across. Trains operated at very low speeds. We had nowhere near the frequencies we have today. Today there are over 1,200 trains a day moving in Canada. We've now got an issue because of the densities and the speeds that didn't exist in the past.
Our friends south of the border, to their credit, have run a much more aggressive program than we have run here in the last 10 years, and it has made a difference in the numbers.
