What's the meaning of level in level a gap, and connection point?
Why can't they put a protective sleeve of the power rail, that the train can still access through. But make it hard for a person to accidentally fall on. For such a sue friend society, I find it strange many people have sued the transit system for accidental deaths
Because insulating a conductor so it doesn't conduct defeats the entire purpose of having a conductor in the first place.
You can have two support structures on either side that are higher than the rail and still level a gap in the middle for the trains connection point to make contact. Then if you fail on it, you shouldn't make accidental contact.
