On the way to Lakewood: Sounder trains began testing the new extension from Freighthouse Square to South Tacoma and Lakewood this week. A train is shown here on the new Pacific Avenue Bridge in Tacoma. Testing continues the next several weeks as crews complete signal and crossing gate testing and monitor train operation on the new rail lines. Sounder passenger service to South Tacoma and Lakewood begins in October. The actual start date will be determined after testing progresses. (Photo by Sound Transit).
