Nothing has run on the tracks for 20 years. Some of it has been pulled up, but the right-of-way remains.

Seattle Transit just announced a $50 billion plan to blast new right-of-way, never mind the trackage could be doubled by re-using that right-of-way for a few million.

You can still see the tracks on Google Maps:

although it has been renamed "Cross Kirkland Corridor" in their attempt to hide what it is. Sound Transit prefers a plan that costs one thousand times as much, still won't serve the eastside, and will not be in service until half the existing taxpayers are long dead.
