Only the end sections where the track and platform start curving to the center. I assume with the coming improvements for Penn Station the safety enhancements will be made. In some places you can't even walk between the elevator shaft and train without bumping the train. Of course that is totally awesome for a railfan..along with that hot greasy smell down on the platforms lol
Yeah most people do watch the gap...but I am thinking more of a kid getting bumped in the mad rush. You know there was a time when busy grade crossings were only protected by cross bucks yet people stopped and paid attention...a lot less accidents than now days with people getting stuck in gates and acting like that is the danger and not the train about to hit them.
