  • 15 of 15 phases are complete, making the project operationally complete.

Why is WSDOT installing the Advanced Wayside Signal Systems?
The system upgrades will result in improved on-time train performance through the elimination of most delays from signal failures. Upgrading the signals will make the system ready to accept Positive Train Control components.

The End Result
WSDOT is working with BNSF Railway, Tacoma Rail, Sound Transit and Amtrak to:

  • Upgrade wayside signal systems components at all control points, sidings and turnouts between the U.S./Canada border and Vancouver, Wash. This is known as the Pacific Northwest Rail Corridor, or PNWRC.
  • The upgrades include cabling work along the tracks near railroad control cabinets.
  • Upgrade wayside signal systems components throughout the PNWRC.

Project Benefits
The Advanced Signal System project upgrades control points, sidings, and turnouts with state-of-the-art wayside system components. This will result in:

  • improved safety
  • added rail capacity
  • increased reliability
  • the potential for future higher speed travel.

What is the project timeline?
BNSF began its preliminary engineering work in early 2012 and began construction on the Seattle to Vancouver, WA section in July 2013. Construction was completed in February 2016.

Financial Information

WSDOT received federal high speed rail funds from the American Recovery and Reinvestment Act (ARRA) of 2009, administered by the Federal Railroad Administration (FRA).
Project Budget -- $47.4 million
