Gravity Train as Energy Storage

Energy grids running on renewable energy sources need storage. The most common way to store energy on a grid scale is through "pumped" hydropower, where the excess energy available during off-peak is used to pump and store water at a higher elevation, which can then be released to produce electricity as gravity pulls it down to a lower elevation again.
