Sound Transit Advances Design on Federal Way Train Base

Sound Transit’s board is poised to award a $350 million contract to Hoffman Construction to advance design and pre-construction on OMF South, a new train maintenance base on a 70-acre Federal Way site south of Downtown Federal Way’s current terminus, with an expected opening by 2031 or 2032. The facility will accommodate 72 next-generation double-length light rail vehicles designed by Siemens and will include the system’s first dedicated test track along I-5. If approved at the March 26 board meeting, this contract will bring the total project budget to $875 million toward the $2.2 billion facility, with construction expected to create 600 jobs and involve 4 million work hours.
