Yes, and on top of that if there were a train line on campus with any high speed train traffic it would be surrounded by tall fences and the pedestrians would be provided with off-level crossing. (One or more tunnels and/or bridges)

This is exactly the case a little ways away at Tufts University in the city of Medford. There's a busy train line that runs through the campus and it's fenced off. Students do sometimes find ways in there and use the right-of-way as a shortcut. Sometimes they get killed doing this--which is why the fence is there in the first place.
