Hi folks, I'm not 100% if this is the right place to post this or not so if its not then my apologies in advance!
I'm going to be flying to Geneva and need to get to Lausanne that day, I've looked at the swiss rail site and it looks like I will be able to get the train there without any problems.

As this is my first time in Switzerland I do have some questions about using the public transport ( I hate being the hapless tourist ) Can I get the train to Lausanne from the airport or would I need to go to the city center to get it? I'm assuming there are ticket offices / machines I can use to purchase the ticket from?

These are probably pretty stupid questions but if anyone could help it would be really appreciated!
