I actually agree with BuildingScout that a 6-foot chain-link fence would actually be a safety issue as it is a barrier in both directions. At the same time, some sort of barrier is appropriate; people, and kids in particular, seem to like walking on rail road tracks. Something to do with stepping on the ties and balancing on the rails I guess. I'd suggest a 3-foot or so hedge. High enough to be unattractive to cross, but not firm enough to be a safety or wildlife issue. Additionally, because it is a soft barrier, the other side doesn't become forbidden space, which is its own sort of draw (drunken bets and that sort of thing).
