A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored energy. The amount of energy available and its duration is controlled by the mass and speed of the flywheel.
Flywheel energy storages are classified into two main groups: low-speed (rotation speed below 10,000 rpm) and high-speed (rotation speed above 10,000 rpm). Low-speed flywheels are generally made of a metal rotor; and a mechanical, or combination of metal and magnetic, bearing.

This document discusses high speed trains and the infrastructure required to support them. It notes that while trains can now travel up to 500 km/h, high speed trains are generally considered those traveling 150 km/h or faster. Existing rail lines are often not suitable due to tight curves and other limitations. Purpose-built high speed rail lines address these
