@Kempy72 It may be equipped with batteries to propel it through short segments where catenary poles and lines are considered unattractive aesthetically, or are not physically practicable (like large intersections). Some US streetcar systems are utilizing this feature now. This one does have a pantograph in the lowered position.
Thanks Keith, Newcastle here in New South Wales has battery operated light rail that is supposed to charge up at each stop. The sad thing is the closed the heavy rail in part to build it. In Sydney’s CBD they have the electric current in an enclosed trench part of the way along George Street and overhead part of the way.
@Kempy72 Maersk summed up the power supply pretty well. It's based on CAF's Acumulador de Carga Rápida (ACR) system. Interesting thing, that the newer Alstom trams are using the same system that CAF built.
@Kempy72 Almost 20 years ago they also had trial runs with a Siemens Combino, then eventually they trashed the overhead wires because they are too "20th century". However in terms of aesthetics, Kaohsiung (and most of the TW cities) have much bigger issues than some wires.
