King Street Station Track and Signal Improvements
Seattle, Washington

The scope of the design work includes the provision of all special trackwork to achieve Amtrak’s operational goals, the extension of Station Tracks 6 & 7 to maximize storage capacity, and the provision of a new passenger station platform adjacent to Station Track 7 which will adhere to all level boarding requirements. Other scope of work items include a combination of aerial and ground survey, a geotechnical investigation, modifications to the existing storm water collection systems, and the potential relocation of two 480-volt wayside power supply boxes at the end of Station Tracks 4 & 5 and Tracks 6 & 7. Our team was also responsible for the conceptual signal design and for providing seamless coordination among all relevant project stakeholders such as Amtrak, BNSF, Sound Transit, WSDOT, the City of Seattle, and the FRA. Amtrak’s objectives include reaching the following service outcomes pertaining to the Pacific Northwest Rail Corridor (PNWRC) Program:
1.     Accommodate a growing number of intercity passenger trains;
2.     Increase operating speeds for arriving and departing trains; and
3.     Allow for more efficient train movements between Amtrak’s Seattle Maintenance Facility and westerly platforms of King Street Station.
