TITLE: Travel from Milano (Italy) to Loussane (Switzerland). Some doubts.
POST: Hello next 23 of July I'll arrive to Milano to visit a friend of mine. I will be there just 2-3 days and then I'll go to Loussane (Switzerland), I didn't bought any ticket that part because I was unable to buy a train ticket and there was no planes.

So, what options I have to do milano-loussane? (train, bus), could any local citycen tell me prices and ask in the train companion if trais use to be full or I could just bought the ticket when I arrive there.

Sorry for my english, I'm spanish and I'm bad with grammar if you don't understand something I'll write it in another way.
TL;DR: 
Price of a train ticket from Milano to Loussane and if I could buy it the sae day or it will probably be full/expensier?
