Unless you've got access to a continent-gobbling exotic GT and an immunity to speeding tickets, everyone who's ever traveled Europe knows that the preferred way of getting around the Old World is via train. (Heck, even us car-crazed nuts here at Autoblog take the train for European auto shows.) But for one high-speed train service, the experience is about to get a little bit more... automotive.
If you're traveling between continental Europe and Britain and care about the environment, you might want to consider alternatives to flying. Since there are no bridges across the English Channel, that leaves the channel tunnel and the EuroStar train as the only option, (unless you're a really strong swimmer).
