That's a really good analogy. No one's manning the station and the structure already exists so the marginal cost is pretty low.

- canthonytucci 11y agoMonetary cost, sure. What about the cost on the environment to slow the train down and bring it back up to speed?

- Gibbon1 11y agoI'm guessing very small train, probably 30ton weight. Max speed 33m/s. So accelerating 30,000 kg to 33m/s... what E = 1/2 * 30000 * 33^2 = 16335000J or 4.5kwhr at $0.20 kwhr that's about $0.90 in electricity costs.
