is supplying ultracapacitors to ABB for its recent contract win to upgrade Philadelphia area rail lines. ABB will install a hybrid version of its high-efficiency ENVILINE wayside energy recovery and storage system for the Southeast Pennsylvania Transit Authority’s (SEPTA) light rail system serving the greater Philadelphia area. When decelerating or braking, a traction vehicle (train, tram or trolleybus) is feeding the regenerated braking energy back into the DC power network.
