The Raide-Jokeri, also known as light rail line 15, will begin boarding passengers on Saturday, 21 October, Helsinki Regional Transport authority HSL announced on Tuesday.

Earlier this month HSL had to cancel a press conference called to announce the start date of the new tram line after one of the new trams derailed and hit a post supporting overhead power lines.
