Sound Transit

What Sound Transit does

Sound Transit (legally the Central Puget Sound Regional Transit Authority), founded in 1993 and headquartered at Union Station in downtown Seattle, is a public regional transit authority that owns and operates multimodal transit infrastructure across the Puget Sound region. Its core service portfolio consists of Link light rail (operating the 1 Line from Lynnwood to Federal Way, the 2 Line from Lynnwood to Downtown Redmond, and the T Line in Tacoma), Sounder commuter rail (N Line Everett–Seattle, S Line Seattle–Lakewood/Tacoma), and ST Express regional bus service spanning more than a dozen corridors. The agency's signature engineering achievement is the Crosslake Connection opened March 28, 2026 — the world's first light rail line to cross a floating bridge — incorporating seismic bearings, University of Washington–co-developed ultra-lightweight concrete, and proprietary pontoon-attachment methods. Supporting products include the ORCA fare payment system (with tap-to-pay for Apple Pay, Google Pay, and contactless cards launched February 2026), GoodMaps LiDAR-based indoor navigation for blind and low-vision riders, park-and-ride facilities, secure bike parking, and transit-oriented development (over 500 affordable housing units at station sites).

Sound Transit's revenue mechanics are those of a public agency rather than a commercial enterprise: the primary inflows are voter-approved regional sales and property taxes (e.g., the ST3 program), federal grants and TIFIA loans (notably a $1.33 billion TIFIA loan and $1.7 billion in Capital Investment Grants for the Crosslake Connection), bond financing, and passenger fares paid via ORCA (standard adult Link fare of $3 for downtown trips, distance-based). The agency is governed by a publicly appointed Board of Directors led by CEO Peter Rogoff, with offices at 401 S Jackson St., Seattle. Customer segments are primarily regional commuters — particularly the roughly 100,000-strong combined Amazon and Microsoft workforces on the Eastside — followed by event attendees (record 225,000 Seahawks parade ridership, 280,000 for a 2026 World Cup match), airport travelers to Sea-Tac, and transit-oriented development residents.

Revenue model

1. Public Transit Fares: Sound Transit generates revenue through passenger fares on Link light rail, Sounder commuter rail, and ST Express bus services. Fares are calculated by distance traveled using the ORCA card system.
2. Public Funding and Tax Revenue: Regional Transit Authority receives funding through voter-approved tax measures including property tax increases and transit sales taxes. Mayor Wilson proposed doubling Seattle transit sales tax from 0.15% to 0.3%, estimated to raise $138 million annually.

Core offering

Sound Transit operates multi-modal regional public transit across the greater Seattle metropolitan area: Link light rail (50 stations, 99 track miles, light rail vehicles carrying 700 passengers every ~6 minutes at peak), Sounder commuter rail connecting Everett–Seattle–Tacoma–Lakewood, and the ST Express bus network, with the Stride bus rapid transit system scheduled to launch in 2028–2029. Services are accessed using the ORCA regional fare card and tap-to-pay system.

Product overview

Sound Transit operates as a unified public transportation platform offering multiple transit modes that work together to serve the Puget Sound region. The core offerings include Link light rail (operating 1, 2, and T Lines), Sounder commuter rail (N and S Lines), ST Express regional bus, and the upcoming Stride bus rapid transit service. These services are unified through the ORCA fare payment system which supports contactless payments including Apple Pay and Google Pay. Supporting infrastructure includes park-and-ride facilities, secure bike parking, and transit-oriented development projects at station areas. The system recently achieved a major milestone with the March 2026 opening of the Crosslake Connection—the world's first light rail on a floating bridge—connecting Seattle to Bellevue and Redmond, while ongoing expansion includes the Federal Way Link Extension, Stride BRT, and future West Seattle, Ballard, Tacoma, and Everett extensions as part of the ST3 program.
