Over at KiwiReport, a writer named Serena Carsley-Mann asks a good question: “Why do trains in America function so different from trains in Europe?” Unfortunately, she mistakenly thinks the problem is that “trains in America function so badly.”
In fact, America has the most efficient rail system in the world. It is European trains that function badly. I’ve discussed this before in my blog, but since writers like Carsley-Mann continue to get it wrong, it is worth repeating.
According to a Pew study, freight shipped by truck uses about ten times as much energy, and emits far more greenhouse gases, per ton-mile than freight shipped by rail (see page 2). Because rail cars weigh more, per passenger, than automobiles, rail’s comparative advantages for passengers are much smaller, and unlike trucks it will be very easy for cars to close the gap: a Prius with a average of 1.67 occupants, for example, is more energy efficient than almost any Amtrak train. Thus, to save energy, it is better to dedicate rail lines to freight rather than to passengers.
This is what the United States has done, but it is exactly the opposite of what Europe has done. According to a report from the European Union, 46 percent of EU-27 freight goes by highway while only 10 percent goes by rail, while in the U.S. 43 percent goes by rail and only 30 percent by road. Thus, we’re using our rail system far more effectively than Europe. This is not just from an energy view but also from a consumer-cost view, as rails cost less than trucks for freight but more than cars for passengers.
