Mark Blitzer, left, of Seattle and Jim Roche of Puyallup have the train car to themselves as the Sounder heads northbound out of Tacoma on Monday afternoon, the first day of the "reverse commute" service. "I take the train for fun," Blitzer said. "What's cool is that I used to take the bus back. Now I can take the train back" to Seattle. The reverse commute trip, in effect Mondays through Fridays, departs the King Street Station in Seattle at 6:10 a.m. and arrives at the Tacoma Dome Station at 7:10 a.m. The return trip departs Tacoma at 4:45 p.m. and arrives in Seattle at 5:45 p.m. A one-way ticket for adults costs $4.75. Sound Transit also operates a special Sounder train on Sundays when the Seattle Seahawks have a home game at Qwest Field. For more information, visit www.soundtransit.org.
