Sounder Yard Expansion
The Sounder Yard Improvement projects are part of the ST2 system expansion plan approved by voters in 2008. The improvements are being made to accommodate additional Sounder Train service starting in late 2017.
Sounder Yard Expansion (Third Track)
The existing Lakewood rail yard site will be modified to store the seven train sets needed for additional Sounder train service beginning late 2017. These improvements will be made within the railroad right-of-way between Steilacoom Boulevard Southwest and 100th Street.
Proposed improvements include:
- Construction of a third layover/storage track
- Upgrades to train crew accommodations
- Addition of 45 employee parking spaces
- Updates to existing yard roadways, the site lighting security system, and drainage facilities
