Sadly, the proposal is too little, too late, and too expensive. Instead of spending $$$ on more studies (yawn), just grant a zero tax liability to any private company and its employees that will build and operate rail mass transit in the Tidewater.


Things we know or expect to happen:
[A] Fossil fuels will cease being cheap and / or plentiful.
[b] Energy derived from non-fossil fuel sources is still more expensive. But that may change as [A] gets worse. But at least sustainable sources of energy won't suddenly run out.
[C] The most viable sustainable form of energy is electricity - derived from solar, wind, water, and so on.
[D] The most energy efficient form of land transport is steel wheel on steel rail (low coefficient of rolling resistance).

Internal combustion engines, on average, only use 25% of the energy of their fuel to move. The remainder is lost as waste heat. (Yipes!). Even vaunted hybrid electric vehicles are still energy wasters. To compound matters, stop - and - go travel wastes energy via braking (heat) and acceleration.

We know there are six principles for efficient surface transport:
a) reduce the frontal area per person;
b) reduce the vehicle’s weight per person;
c) when traveling, go at a steady speed and avoid using brakes;
d) travel more slowly;
e) travel less; and
f) make the energy chain more efficient.

An electric powered train / tram / streetcar meets a, b, c (*regenerative braking recovers energy), and f. And we'd rather be able to ignore d and e.

An electric traction motor efficiency is between 85 - 95% (depending on configuration, etc), in contrast with Internal combustion engines (roughly from 25% otto cycle to 50% diesel cycle).

In short, we need to acknowledge that electric rail is our only viable alternative to deal with the demise of the Age of Oil.
