We take a risk-based approach in our audits. We concentrate on railway companies which we believe represent the highest risk of accidents. Of course, there are smaller railway companies with only two or three employees. These companies switch wagons from point A to point B. They are responsible for only a couple of kilometres of track. We inspect them once in a while; they rarely have any accidents and there is not much happening in that regard. Trains travel at very low speed on those tracks.
Most of our work is focused on CN, CP and VIA Rail.
