“Lesson From The A380 And California HSR: Smaller Is Better In Transportation” (Forbes), by Brad Templeton, contains a lot of interesting numbers:
In the Department of Energy Transport Energy Data Book you will see some surprising numbers. For example, for transit buses you’ll see that the average American bus uses 4,102 BTUs per passenger-mile, while the average car uses 2,939. (A gallon of gasoline is around 115,000 BTUs.) Yes, US bus ridership is so poor that it would use less energy to move all bus riders in cars, at the national average of 3 people for 2 cars. You don’t even need to fill all the seats, and the cars are just average efficiency. The Toyota Prius is twice as efficient as that average car. People driving around alone in hybrid cars out-green the bus system.
You can compare what you would guess is an efficient electric train, the New York MTA subway. The DoE reports it uses 503 BTUS (of electricity, not heat) per passenger-mile. Even measuring the heat, that’s better than those cars and buses, but about the same as that Prius.
Looking at the MTA again, it spends about $16B to for 13B passenger miles, or $1.23 per passenger mile. Typical car ownership costs in the USA for late model cars is 50-60 cents per vehicle-mile, plus parking. Drivers get subsidies (though they pay gas taxes and other taxes for the roads) but the MTA isn’t paying for its tunnels either.
This is consistent with what I’ve heard from other sources: The idea of building and maintaining rails is obsolete for passenger transportation.
Separately, the article covers the demise of the Airbus A380, which saddens me because I’ve heard that it had the lowest level of cabin noise of any airliner ever produced (the A350 is a close second) and I never got to experience it (there have been some A380 flights in and out of Boston, but they are not common).
Maybe the countries that say they are morally obligated to assist refugees will snap up all of the A380s and send them out daily to pick up 1,000 refugees at a time from the world’s poorest and most troubled regions. If you are sincere about wanting to help people, why demand that they walk 1,000 miles to get that help?
