Not sure where the rail with no fencing is, but it's pretty common around the world to not have fencing on long stretches of track in unpopulated areas.

I just read the article you linked, and while I am just taking the article interviewees word for it, it sounds like they are concerned about pedestrian control at intersections in suburbs. Fair enough concern, but that is going to be up to the state to regulate I think. Rail companies will cut where they can, it's still a heavy industry, not exactly the poster children of ethics.
