Editing Ground-level power supply (section)

===Ansaldo Stream===
The first modern ground-level power supply system to be developed is the [[:it:Stream (trasporti)|Ansaldo Stream]] system. STREAM is an acronym that stands for "'''S'''istema di '''TR'''asporto '''E'''lettrico ad '''A'''ttrazione '''M'''agnetica", meaning "System of Electric Transport by Magnetic Attraction". The system uses a channel in the road made of insulating composite [[fiberglass]] material which contains a flexible copper strip; a vehicle passing over the channel with a special magnetic [[contact shoe]] raises the conductor to the surface, allowing power to flow to the vehicle. Segments of the strip are powered only when a vehicle passes over them. The system was developed in 1994<ref name="Deutsch">{{citation |url=http://elpub.bib.uni-wuppertal.de/servlets/DerivateServlet/Derivate-1021/dd0303.pdf |pages=209–214 |title=Einsatzbereiche neuartiger Transportsysteme zwischen Bus und Bahn |last1=Deutsch |first1=Volker |year=2003 |publisher=Bergischen Universität Wuppertal}}</ref> and trialed on a public tram line in 1998,<ref name="Baggs" /> which was eventually dismantled in 2012.<ref>{{citation |url=https://www.triesteprima.it/cronaca/partono-i-lavori-per-la-rimozione-delle-rotaie-di-stream-in-via-mazzini.html |title=Partono i Lavori per la Rimozione delle Rotaie di Stream in via Mazzini |date=16 February 2012 |website=TriestePrima}}</ref>
