Thank you, Mr. Chairman.
Good afternoon, gentlemen from CN.
I'd like to go back to the safety system that was implemented at the railways. You said earlier that it had been in effect at your company for five years. So you've had the time to familiarize yourselves with the system and to implement it properly.
In your view, has it enhanced security measures? Has the system enabled you to improve safety, or has it forced you to do so?
