Grassy trams are better than dead asphalt, but monoculture lawns are still not the best. I'm not sure what the best translation of the official name would be, but I guess meadowy tram would fit. Much lower maintenance and increased resilience to heat and dryness are nice bonuses.
This is a 1km stretch of tramline 13 running through a park in Helsinki, Finland.
Great to see it. Those look very nice!
