Editorial Comment:  I remember reading in Edwin Black’s Internal Combustion about the Milwaukee Road, an electric railway in the early decades of the 20th century, and thinking that you could possibly plan routing freight trains in such a way that traveling downgrade with regenerative braking could power traveling upgrade without any need for excess power.  Actually, now Fortescue Williams, a hard rock mining company, operates an "Infinity Train” in Australia that never needs charging using this idea.
