Jokeri light rail(Helsinki Tram Line 15) opened today
https://en.m.wikipedia.org/wiki/Jokeri_light_rail
The new tram Line is called "High Speed Tram" operated with 70 km/h at the maximum speed, connecting suburban districts around Helsinki. I guess this is one of the biggest milestones in the public transportation history of Helsinki in terms of its speed and improvement on convenience, when moving between suburban areas.
