Has anyone ever taken the Lavaux Express Train that runs out of Lutry and Cully up through the vineyards? We have friends coming in July from the US and I was wondering if this is fun. What I really want to know is if the train actually stops at the vineyards for wine tastings along the route. The website makes it look like the trips are only 1 and a half hours long, which doesn't seem long enough for stops along the way.
