Flywheels are fixed at stations in the train system that can restore 30% of the energy through a regenerative braking mechanism.
That''s one reason why regenerative brakes don''t save 100 percent of your braking energy.

A mechanical arrangement intended for the storage of a modest amount of energy as is the case in regenerative braking, is proposed in this paper. Because the transfer of kinetic energy both ways between the vehicle and the flywheel takes place directly without conversion to another form of energy, high efficiency is anticipated.
A hybrid split drive system that uses an onboard flywheel-based rechargeable energy storage system is here the starting point. Recovering kinetic energy via a flywheel through regenerative braking seems promising for self-propelled vehicles with frequent starts/stops (see [2, 3]). Such a system will have a meaningful effect on
