Technology and Infrastructure
The tram network is built almost exclusively on the streets of Helsinki, making it a traditional tram system rather than a light rail one. The track gauge is one metre. The network consists almost entirely of double track. In some parts the tracks are separated from other road traffic; elsewhere they share road space with cars and buses.
The trams are powered with electricity conveyed by overhead wires. Trams have their own traffic lights, distinguished from normal lights in that they are based on symbols of single colour: an upward-pointing arrow signifies "go", a horizontal line "prepare to stop" and the letter S "stop". The traffic lights are synchronised to allow tram and bus traffic to flow relatively smoothly. This system is called HeLMi (Helsinki Public Transport Signal Priority and Passenger Information).

Famous quotes containing the word technology:
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
