There has been a few e-mails regarding taking Sounder to see the Sounders FC and your in luck, at least for one direction.
Those who live near the South Sounder line can hop on the 4:45pm train departing Tacoma to Seattle and get to today’s opening game of the Seattle Sounders FC vs New York Red Bull. You will only have 20 minutes or so to spare but thankfully Qwest Field is a very short walk!
For future games, gamers can take the 4:45pm and 5:35pm trains to Qwest Field. Most games will start between 7pm and 8pm.
After the game however, you are on your own. If you live in Sumner or Puyallup, you unfortunately have no way of getting back home since there is no bus service to Sumner or Puyallup from Seattle, Federal Way, or Tacoma after 8:30pm. Those who do live in Tacoma can take Sound Transit route 594 until 11:34pm. Those in the valley, can take the King County Metro route 150 to Tukwila and Kent until 1:23am, then the 180 or 565 to Auburn Station at 2:16am and 10:34pm respectively.
Those on the North Line, you unfortunately do not have a reverse commute train available to return to Seattle. From Everett Station, you can take take Sound Transit Route 510 which stops at South Everett Freeway Station, NE 145th and NE 45th to 5th and Jackson followed by a short walk to the stadium. The last bus is at 11:45pm.
