Lesson 1 about pantographs occurred between Prague and Dresden and will not be repeated.
Near the Catedral in Seville the visual impact of overhead wires for their trams was not acceptable. So in the photograph you will notice a tram with its pantograph touching a short overhead rod, perhaps 5 metres long, which the pantograph extends to and touches for about 30 seconds whilst passengers get on and off. The pantograph then retracts and the tram moves on to the next tramstop.
It only takes about 20 seconds to recharge the "super capacitors" providing sufficient energy for 1 km.
ah, always good to expand my knowledge of all things pantographic
