How About Trains?

Dang! Now I have to change my mind again. I began my research into the energy efficiency and carbon footprint of different modes of transportation with a preconceived notion. That notion was that rail would be the best. I was wrong. It turns out (unfortunately for comfort and time) that the bus is most efficient in terms of miles per gallon of fuel per person (MPGPP). Buses give about 150 . Trains give only 50, very similar to cars. Planes are only slightly less efficient giving 41 MPGPP.
