And how about in Italy, do I need buy some ticket such pass inItaly or buy retail in Train station?

Thank you for your kindness help, because it is first time go bymy shelf. Hope you will reply as soon as possible.

Hello ear1pro! Since you already have a Eurail Select Pass covering Switzerland, you won't need an additional pass for this country. Please review the details mentioned at the Eurail Select Pass page and follow the link 'Overview of the Swiss network on which the Eurail Select Pass is valid' for details. Only if you've planned intensive traveling in trains/cable cars not listed on this map, an addtional pass might come in handy. I'm not into details for Italy, but I expect the same to apply here.

Dear Annika,
Thanks for your kindly reply, Hope I can enjoy my first trip in Switzerland... Thank you so much. by the way, can a Eurail Select Pass be a discounted travel for Cable Car in Zermatt?

Hello earpro1,

Eurail passes do not provide discounts to the Zermatt cable cars. Just review the link Annika explained about and you'll see exactly where it's valid.

Dear Arno,

So, what should I do, what kinds of ticket I should buy. Thanks, sorry to many questions

Dear Sir,

I saw that ticket from Brig to Milan, is needed to Reserve before go, can I reserve it in another city train station such as from Zurich or Luzern before that day
?. Thank you

Dear earpro1,

You can book train seats at any manned station or online. It's recommended to do it as soon as possible to make sure your desired seats are available. Theoretically you can do it even on the same day, but of course the chance increases that seats are taken.

Dear Sir,

I will with My Father which have age 73 years old now, and have a little probleem is His heart, arround 35% quality of His Heart. What do you think, about Oxygen Air in Zermat, I will stay in Bristol Hotel Zermatt. Is it indicate thin Air in there?. Thank you.

Hello earpro1,

I would guess that Zermatt at 1600 m should be no problem yet, but going up into to mountains from there is probably not a good idea. But you can best consult a doctor for medical advice.
