As if that wasn't enough, the whole thing also promises to be funded entirely by micro-payments from the public (which would also determine its final size), and be completely self-powered, with it relying on a combination of solar power and regenerative braking from the lifts in the towers.
The new locomotives are designed for easier maintenance, will improve energy efficiency by using a regenerative braking system that will feed energy back into the power grid and will enhance mobility for the people, businesses and economy of the entire Northeast region.
The hybrid recaptures energy through a process known as regenerative braking -- where the energy normally lost through braking or coasting goes to power the electric motor.
