Siemens was selected to provide the power infrastructure for Seattle’s latest expansion — the Northgate and East Link lines — of the Seattle Sound Transit light rail system. Siemens will supply 13 traction power substations (TPSS), two medium voltage substations (MVSS), and one cross passage tunnel tie station on the Northgate and East Link and fully integrate these additions into the existing infrastructure. It will also upgrade one existing substation supplied by Siemens in 2008.
