The challenges we are facing is in recruiting our inspectors and the industry is facing the same thing, in terms of massive retirements.
We have visited one of the centres for training that CN has put in place, so the industry is putting a lot of effort into this, from what we have seen, in terms of recruiting very early and training new employees. We haven't seen that being an issue in terms of their ability to be in compliance with regulations. Certainly, we pay close attention to training of those employees.
