Electricity and Power Storage - Ares North America
Someone is finally getting around to implementing heavy electric trains on long grades as a gird energy storage system. Though admittedly the current system is smaller scale and for load leveling a wind power plant, and using narrow gauge rail along with a third rail in rural settings seems like a poor choice in the long term. Concept is sound, but having individual motor/generator cars is an interesting compromise. As long as the primary weight can be provided by cheap gravel, I suppose it doesn't matter.
