What is the power supply for trams?
Most light rail or tram systems get their power from overhead catenary systems. Typical voltages range from 600V–750V DC, with more recent installations tending towards higher voltages. These voltages are lower than those used by traditional electrified railways, which use much higher AC voltages up to 25 kV.
How do trams pick up power?
A pantograph (or pan or panto) is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings.

Why did Dublin get rid of trams?
The advent of buses and large-scale competition meant that buses often ran the same routes as the trams and would jump in front to grab customers, and buses were able to move into Dublin's expanding hinterland more quickly and at less cost than the trams, and the belief that trams were outdated and old technology, ...
