Rail - King Street Station Track Improvements - Complete March 2017


May 2017

  • This project was declared operationally complete in March 2017.
  • Work includes designs for new tracks and switches that will allow for more efficient train movements between Amtrak‚Äôs Seattle Maintenance Facility and westerly platforms of King Street Station.

Why is WSDOT improving the tracks at King Street Station? 
WSDOT's Amtrak Cascades, Amtrak long-distance trains, Sounder commuter trains, and BNSF Railway Company freight trains all use the tracks at King Street Station.

The number of passenger trains using the station is planned to increase in the future. These track improvements will support more efficient train operations at the station and reduce schedule delays.

In a separate project, WSDOT worked with its public and private partners to renovate King Street Station. Learn more about the King Street Station renovation project.

The End Result
Reconfiguring connections and upgrading switches to the BNSF main line tracks south of the station will better accommodate the growing needs of WSDOT, Amtrak, Sound Transit, and BNSF.

The work will:

  • Extend station tracks
  • Relocate power supply boxes
  • Install additional turnouts
  • Add a signal system within station tracks
  • Modify the main-line signal system
  • Add a new station platform and canopy
