Of course they must. It's a two ton block of metal traveling at about 10 meters per second. Not yielding to the massive energetic slab of metal is quite simply irrational. Cars yield to trucks too. Anyone who doesn't has some kind of death wish. Some reality denying law doesn't really invalidate physics.
That's what always gets me with these "won't you think of the poor pedestrian" arguments. I never see people arguing for their god given right to stand in front a moving locomotive. Aircraft? Only time pedestrians are allowed anywhere near the runways where they accelerate is to board the plane. But somehow with cars it's alright. Dude walks in front of a train and it's suicide. Same dude walks in front of a car and it's murder.
