Transport Canada requires passenger trains to have 2 sets of horns, they are usually modified Nathan horns, i can't remember the designation for each of them
0:47 For my fellow Canadians, it's important to know, activated railway crossings are legally considered Red lights, so running one will carry the same penalties as well as failure to yield. Don't run the crossings, it's dangerous and illegal.
@Joshua Likes Trains • 139 years ago they have only one… most of the go line has quite zone so if they had to sound the horn, it would be an emergency(other than the Barrie line). I take the go train a lot and there is only one horn.
