http://www.theoildrum.com/node/2377The High Speed Passenger Rail Act - BackgroundEnergy ImplicationsPassenger air travel in the US in 2005 got about 45 passenger-miles per gallon of fuel, emitting 140 million tons of CO2 in total (1). Passenger cars on highways traveled over 1.5 trillion miles with an average of 1.59 occupants, at about 44 passenger-mpg, emitting about 750 million tons of CO2. Both air and automobile are heavily dependent on liquid fuels whose future supply is uncertain.
Successful high-speed rail systems, implemented in Japan and Europe, particularly the French TGV system, run on electricity with an efficiency equivalent to 300 to 500 passenger-mpg. And electric power is the easiest form to generate from new energy sources such as wind and solar energy. High-passenger-load high-speed rail would dramatically reduce the impact of the passenger transportation sector on energy consumption and CO2 emissions.
Current US Passenger Rail Status
Mention passenger rail in the US and people think first of Amtrak and its perpetual funding crisis. Amtrak’s total ridership of 25 million per year is dwarfed by the 658 million for air travel and the billions for cars. But commuter rail is widely successful across the country, and “light” inter-city passenger rail has been making a comeback in recent years thanks to state funding to help offset pollution and congestion, for a combined total of 750 million annual trips in 2003 (2). Americans are at least as willing to travel by train as by airplane. The problems with Amtrak are simple to state: unreliability, coupled with high cost and low speed. On some routes, 96% of Amtrak trains arrive late (3). On all but a very few routes, taking the train takes longer than traveling by car because the trains are limited to 79 mph. Yet the cost can be comparable to or even higher than plane fare.
Train travel has one advantage over road or air: it’s much easier for business travelers to work on the way. But that doesn’t help if they arrive at their meetings hours late. States, seeing the importance for local development and pollution-prevention, have taken matters into their own hands and funded significant upgrades for inter-city passenger rail service in Washington state, California, Illinois and Pennsylvania, and other states appear eager to join (3).
