- I know that light-rail systems such as BART (here in the SF Bay Area) help
- to reduce traffic congestion but, is such a system actually any more fuel
- efficient?
-
- I am thinking in terms of energy input per passenger-mile. How does the
- efficiency compare with transportation by auto? One advantage I can see is that
- a train car is usually full during commute hours but, must autos carry a single
- passenger. It seems a train should be more aerodynamically efficient as well.
- Are these the only advantages or are there obvious others?
-
- How much power is lost in distribution for an electric rail system like
- BART?

- Thanks
