Trains have always been popular in parts of the world. In this article, CNN shows how the 'green' aspect of train travel has increased their popularity around the world, and yes, even the U.S.
"Faced with global climate change, many around the globe -- from governments to companies to individuals -- have also warmed to train travel.
Traveling by rail is on average three to 10 times less CO2-intensive compared to road or air transport, according to the UIC, a Paris-based international organization of the railway sector.
Meanwhile the Boston Consulting Group estimates that by 2020 passengers will be able to travel faster point-to-point by high-speed rail than by plane on nearly half of Europe's densest air routes."
