Southeast King County Commuter Rail Feasibility Study Complete October 2010

WSDOT recently completed the Southeast King County Commuter Rail Feasibility Study. This study was undertaken at the request of the Legislature with the expressed intent of determining the feasibility of commuter rail service on the existing rail line from Maple Valley and Covington to the Auburn Sounder station using diesel multiple unit (DMU) technology. This feasibility study concluded that commuter rail service is feasible provided that certain conditions are met.

This study resulted in WSDOT and our partners having a better understanding of the costs of potential DMU commuter rail and enhanced bus services in Southeast King County. This study will also provide valuable input about future transit needs into the local comprehensive plans of Auburn, Black Diamond, Covington and Maple Valley and has already provided valuable input into the Puget Sound Regional Council’s long-range transportation plan, Transportation 2040. With our partners in this study, we have identified future needs in Southeast King County that had not previously been addressed in the PSRC’s long-range plan. The completion of our study has also resulted in improved transportation planning coordination between WSDOT, the local
jurisdictions and King County Metro.
