User:Coccodrillo/List of alpine railway crossings

I'm trying to write a list similar to List of railroad crossings of the North American continental divide for the Alps. There are some problems:

  • how to define the two sides of the Alps? My idea is the line dividing the Adriatic and Donau waterheds
  • what should be indicated as company? the infrastructure manager or also the main operator?
  • should railways crossings of other mountain chains be added (Appennini, Pyrenées, etc)?
  • should east-west crossings be included (Arlberg)?
