An elevator system includes a first propulsion system for imparting linear motion to an elevator car; a controller generating control signals for the first propulsion system; a brake for holding the elevator car; an energy storage unit; and a second propulsion system; the controller configured to at least one of (i) access the energy storage unit to power at least one of the first propulsion system and second propulsion system upon a fault during upward travel of the elevator car (ii) power the second propulsion system upon a fault in the first propulsion system during upward travel of the elevator car and (iii) delay applying the brake until the elevator car speed is less than a threshold upon a fault during upward travel of the elevator car.
