How to read this list

Every schedule and price is quoted from the official page on the date shown, shortened, never normalised. If the page did not publish it, the entry says so instead of guessing. A quote older than six months is marked to confirm.

Links are official only: the operator, or the ticketing provider the operator names. No reseller, no commission. The list is ordered by country and name, and nothing here depends on what pays.
