The RS website says "rail passes also aren't accepted on TRENORD trains (which operate in some areas of northern Italy, including the Milan–Varenna–Tirano line between Milan and the Swiss border)."

However, these trains are mentioned on the Eurail website: http://www.eurail.com/plan-your-trip/guide-eurail-train-reservations/how-do-i-book-my-reservations/train-reservations-italy
When I try to book a train from Milan to Varenna on the Trenitalia website, there is no option to get a Eurail Global Pass price. On other routes, like Milan to Florence, the Global Pass price is there. Can someone confirm if the Eurail Global Pass will or will not work from Milan to Varenna?
Thank you
