I want to make one quick point.
The cost of relaying those tracks is very, very prohibitive. As Mr. Emerson said, the infrastructure replacement 10 years down the road, if you make a mistake, is so prohibitive it will never get redone, so you do have to be very careful. Municipalities, when they are considering it, need to consider that replacement cost.
Most short-line railway beds in Canada would never be laid again if they were to be bad laid, so from that perspective, they are very valuable assets.
