2018 FHWA REGIONAL COMPETITION: PROJECT SPONSOR FOLLOW-UP QUESTIONS

AGENCY: PROJECT: South Sounder Capacity Expansion

Question #1: Per the discussion at the regional presentations, please provide additional information on the overall system benefits of the track improvements.

Answer #1:

Track improvements (from single track to double track) are planned to be designed and will increase rail capacity of the overall system, allowing more trains to use the corridor (commuter, passenger and freight trains). Improvements could include: • Double track the rail line from Portland Ave Bridge to TR Junction, in Tacoma • Double track the rail line from D ST to 66th St, in Tacoma • Add additional track at King St Station, in Also, relocating the Kent Station platform features will prevent occasional blockage of nearby streets during boarding/deboarding at Kent Station.

Additional track & signal infrastructure will be determined on a segment by segment basis along the rail corridor between Seattle and Nisqually. Sound Transit will coordinate with BNSF, WSDOT and Amtrak to identify long-term capacity needs.

Question #2: Please clarify any overlap in service and the timing of improvements between this investment and current and future extensions.

Answer #2: Sounder and Link light rail serve different destinations and markets, so there is not an overlap in service. However, Tacoma, Seattle and Everett are “major transfer hubs” and are served by both light rail and commuter rail (as well as express and local buses, Greyhound/Bolt buses and Amtrak trains.) Those major transfer hubs allow transfers from one service to another.

Sounder commuter rail operates over relatively long distances between stations and has only one station in central business districts. Sounder serves fewer stations and operates at higher speeds as compared to light rail.

Sounder and Link have different alignments and serve different locations: • After Tacoma, Sounder generally follows the SR 167 corridor, serving Puyallup, Sumner, Auburn, Kent, Tukwila and Seattle. • After Tacoma, Link generally follows the I-5 corridor, serving Fife, Federal Way, Kent/Des Moines, SeaTac and SeaTac Airport, Tukwila and Seattle.

Timing of the Sounder and Link Improvements: • In ST3, the South Sounder Capacity Expansion with extension of platforms for 10-car Sounder trains, is scheduled to open in 2027. The extension of Sounder to JBLM and Dupont is scheduled to open in 2036. • The extension of light rail from Federal Way to Tacoma is scheduled to open in 2030. See maps of existing/future Sound Transit service, showing different alignments of commuter rail and light rail and the timing of when extensions are scheduled to open. SOUND TRANSIT FUTURE SERVICE
