Yeah, they should, but they don't own the ground or the airspace above the tracks. Amtrak (or Conrail, or whatever agency owns the railroad right-of-way) may have good reasons why they don't want it covered. It could actually be a security or safety issue.
If we are lucky, someone might be able to convince them to sell or cover it themselves.
