Just in from Sound Transit:
Sounder Early Trains Tuesday Afternoon
In addition to its regular commuter rail service, Sound Transit will run an early southbound train from King Street Station at 2:30 p.m. and a northbound train from Tacoma Dome Station at 3:50 p.m.The 2:30 p.m. southbound train from Seattle will depart Tukwila at 2:42 p.m., Kent at 2:49 p.m., Auburn at 2:56 p.m., Sumner at 3:05 p.m., Puyallup at 3:09 p.m. and arrive in Tacoma at 3:29 p.m.The northbound train to Seattle will depart Tacoma Dome Station at 3:50 p.m. Puyallup at 4:02 p.m., Sumner at 4:07 p.m., Auburn at 4:15 p.m., Kent at 4:22 p.m., Tukwila at 4:29 p.m. and arrive in Seattle at 4:48 p.m.
Sounder service to Everett will operate on a regular schedule, with the first northbound train leaving Seattle at 4:05 p.m. Link light rail and Tacoma Link will also operate on a normal schedule.
This seems like a good idea and in my experience Central Link and Sounder are always a better bet if the snow really does hit.
