Seattle has opened a subsection of their new Light Rail Line (Line 2). It doesn’t connect to downtown yet (still working out engineering issues with the floating bridges), but they were smart enough to start running the section already complete.

Massive (by US standards) ridership has ensured. People needed the transit!

Seattle’s geography is really tough for transit systems. The quantity of bottlenecks from riders and mountains is quite high. Trains are a necessity going forward to tie together the region.
