Train Testing on Point Defiance Bypass January 16 - 17

Dynamic Train Testing January 16 - 17

On January 16-17, Sound Transit in partnership with WSDOT and Amtrak, will run trains on the Point Defiance Bypass for railroad signal testing. Trains will run from Tacoma Dome station to the Nisqually Junction. Testing will take place from 8 a.m. to 4 p.m. both days with trains running at speeds up to 79 mph. Travelers may experience traffic delays at railroad signal crossings and the public is asked to use extreme caution near the railroad right-of-way. 

To ensure public safety, local police officers will control each at-grade railroad signal intersection during the two day testing period.

Potential traffic delays could occur at the following at-grade signal crossings:

  • South 66th Street                                                 
  • South 74th Street
  • Steilacoom Boulevard Southwest
  • 100th Street Southwest
  • 108th Street Southwest
  • Bridgeport Way Southwest
  • Clover Creek Drive Southwest
  • 41st Division Drive
  • DuPont – Steilacoom Road

This testing is in advance of the eventual resumption of Amtrak Cascades service to the Point Defiance Bypass later this year
