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)?
