Monday was the first morning commute during a work week as Seattle entered 10 weeks of interrupted light rail service. Riders navigated a new middle platform at Pioneer Square and waited twice as long for their rides.

There will be 10 weeks of construction that will cause riders to transfer at Pioneer Square station. The other big change is departure times: trains arrive every 12 minutes instead of six as they used to. This can be a little confusing for travelers so Sound Transit is airing special announcements on overhead speakers. The voice of those announcements used to be a quiet, automated female voice. Now the PSAs are a bit louder -- and male. Sound Transit said this was an intentional choice to get riders' attention. The agency plans to go back to the female voice when construction concludes in spring.

Sound Transit said that aside from some early-morning delays, trains were running on time and at capacity through Seattle on Monday. Changing trains is new for Seattle-area light rail riders. Before, travelers could move from Angle Lake station all the way north to the University of Washington’s Husky Stadium without leaving their seats. Now, every 12 minutes, both the northbound and southbound trains arrive at Pioneer Square station at the same time. A mob of riders flood the temporary, middle platform where Sound Transit “ambassadors” direct traffic by pointing and hollering. In two minutes, both trains depart opposite directions and the platform is deserted except for the dozen or so Sound Transit employees awaiting the next surge. Daily riders said Monday’s commute wasn’t too bad and trains were as full as they usually are for a workday. Sound Transit had warned of packed rides and added a fourth car to their trains in preparation. Janelle Smith-Dozier, who rides to work from Beacon Hill, said she forgot about the changes until she got down onto the platform.

“No problems at all,” Smith-Dozier said. “Got in, got a seat, standing room wasn’t bad.”
