I'll look into this, but there is a procedure--and I'm sure the officials in Drummondville are aware of this--whereby you can apply for a variance on the safety regulations, so that whistles do not have to be sounded. It requires the specific approval of Transport Canada to do that, and they do a special study. Because if they feel that will create a public safety problem, then they will not allow us to not do it, and then we have no choice. It's a law: we must blow the whistle.
I'll happily follow up on Drummondville and see if we can find out more and I'll get back to your office.
