Sounder (reporting mark SDRX) is a commuter rail system that serves the Seattle metropolitan area in the U.S. state of Washington. It is managed by Sound Transit and operated by BNSF Railway on 82 miles (132 km) of tracks, primarily owned by BNSF, using equipment maintained by Amtrak. Sounder is split into two lines that intersect at King Street Station in Seattle: the N Line to Everett and the S Line to Tacoma and Lakewood.

Sounder trains typically operate during peak periods, with trains to Seattle in the morning and to outlying areas in the afternoon. Limited midday service is offered on the S Line and special weekend trips are run on both lines for sporting events and major events. In 2023, the system had a ridership of 1,630,000,[2] or about 7,300 per weekday as of the third quarter of 2024.[3]

The commuter rail system was preceded by mainline passenger railroad service that began in the late 19th century, including two interurban railways to Everett and Tacoma that operated until the 1920s. After a decade of planning, Sounder commuter rail service was approved by voters in a 1996 ballot measure and construction on its stations began in 1998. The South Line (now the S Line) entered service on September 18, 2000, and was followed by the North Line (now the N Line) on December 26, 2003. The South Line was extended from Tacoma to Lakewood in October 2012 and is planned to be extended further to DuPont by 2045.

Lines

The Sounder commuter rail system comprises two lines that total 81.8 miles (131.6 km) in length and serve twelve stations.[1][4] King Street Station in Downtown Seattle serves as the system's central hub and is the terminus of both lines. The N Line serves three stations and terminates in Everett; the S Line serves eight stations and terminates in Lakewood, with some trips ending in Tacoma.[4] The two lines carried a total of 1.8 million passengers in 2023 and Sounder was the 13th-busiest commuter rail system in the United States by ridership.[1][5]

Train service is primarily operated during weekday rush hours, with trips inbound to Seattle during the morning and outbound to the suburbs in the afternoon. Other services, including reverse commute and mid-day trips are offered on the S Line, while both lines have occasional weekend service for special events.[6][7] Most of the Sounder system uses tracks owned by BNSF Railway, which is also contracted to operate the trains. Amtrak provides fleet maintenance and storage of trains at their Seattle facility.[4][8] The Lakewood–Tacoma segment of the S Line, part of the Point Defiance Bypass, uses tracks that are owned by Sound Transit.[9][10]

N Line

 

The N Line begins in Seattle and travels north for 34.2 miles (55.0 km) on the BNSF Scenic Subdivision towards Snohomish County, where it serves three stations and terminates in Everett.[11][12] It typically uses short trainsets with two or three passenger cars during its normal four round-trips on weekdays; for special event services, the N Line has five-car trainsets.[1] Trains leave King Street Station and cross beneath Downtown Seattle in the Great Northern Tunnel, which was completed in 1904 and was the highest and widest railroad tunnel in the U.S. at the time.[13] The tracks emerge under Pike Place Market and travel through four at-grade crossings along Alaskan Way on the city's waterfront.[14] The N Line continues northwest past Myrtle Edwards Park and under the Magnolia Bridge to traverse the Balmer Yard, a major BNSF railyard in the Interbay neighborhood.[15][16]

The tracks cross over the Lake Washington Ship Canal on the Salmon Bay Bridge, a movable bascule bridge near the Ballard Locks, and pass through Golden Gardens Park.[17][18] The N Line continues north along the shore of Puget Sound and passes under overpasses at Carkeek Park in Seattle and Richmond Beach in Shoreline.[15][18] The coastline tracks run under steep bluffs to the east that range from 80 to 100 feet (24 to 30 m) in height and are prone to landslides during the winter season.[12][19] The line enters Snohomish County at Woodway and turns northeast at Edwards Point to reach the Edmonds waterfront. Its first outbound station is Edmonds station, located adjacent to the city's ferry terminal and downtown.[15][20]

The N Line continues north along Puget Sound until it reaches Mukilteo Lighthouse Park, where the tracks turn east and cross under State Route 525. Trains then stop at Mukilteo station, a two-platform station near a ferry terminal that serves the Whidbey Island ferry.[21][22] The tracks continue northeast along Possession Sound and pass several public beaches before they reach Everett.[15][23] The N Line travels east under Downtown Everett in a short tunnel and turns south to reach its terminus at Everett Station, a multimodal hub with bus and Amtrak connections.[15][24] Trains take approximately 53 minute to travel between Seattle and Everett.[25]

S Line

 

The S Line is 47.6 miles (76.6 km) long and travels south along the State Route 167 corridor from Seattle to Pierce County, where trips terminate in either Tacoma or Lakewood.[11] It follows portions of the BNSF Seattle Subdivision from Seattle to Tacoma, a Tacoma Rail spur, and Sound Transit's Lakewood Subdivision from Tacoma to Lakewood.[12] The S Line uses longer trainsets in five-car and seven-car configurations and has 13 round trips on weekdays—including reverse direction trips and limited mid-day service.[1][26] Trains begin at King Street Station and travel south along the east side of Lumen Field and T-Mobile Park, passing under the retractable roof of the latter, in the industrial SoDo neighborhood.[27] The tracks pass the Sounder and Amtrak maintenance facility near South Holgate Street and continue under the Spokane Street Viaduct;[28] they then turn southeast at Union Pacific's Argo Yard.[29][30]

The line travels southeast through Georgetown and runs between Boeing Field to the west and Interstate 5 to the east.[12] The S Line crosses under the tracks for the 1 Line of the Link light rail system near South Boeing Access Road and continues into Tukwila.[31] The tracks cross under Interstate 5 and begin to follow the Duwamish River and later the Green River near Fort Dent Park and the Starfire Sports complex.[15] Trains then pass under Interstate 405 near the former Longacres horse racing track and arrive at the first outbound station, Tukwila, which is shared with Amtrak Cascades.[32] The S Line continues south through the industrial Green River Valley into Kent, where it crosses under State Route 167 and stops at Kent station.[15][29] The tracks traverse eight at-grade crossings in Kent before crossing the Green River at the city's southern boundary.[33]

The S Line passes Auburn Municipal Airport and the Emerald Downs horse racing track in northern Auburn. It then stops to serve Auburn station in the city's downtown near an interchange with State Route 18.[15] Trains pass through a large railyard and cross over the White River before leaving King County to enter Pierce County near Pacific.[15] The tracks turn southwest in Sumner and serve the city's train station near its downtown. The S Line cross under State Route 410 and over the Puyallup River before it turns northwest to enter Puyallup.[12] The line crosses under State Route 512 and stops at Puyallup station near the Washington State Fairgrounds; it also traverses a series of at-grade crossings in the city.[29][34]

The tracks continue northwest to follow the Puyallup River and make a series of turns along the western edge of the rural valley as it approaches Tacoma. The S Line crosses under State Route 167 and Interstate 5 and leaves the BNSF Seattle Subdivision to travel on a section of Tacoma Rail that includes a 1,500-foot (460 m) trestle.[35][36] The S Line reaches Tacoma Dome Station, a major intermodal hub near the Tacoma Dome with connections to the T Line streetcar, buses, and Amtrak trains.[21] The line moves to the Sound Transit-owned Lakewood Subdivision on a single track that crosses west under Interstate 705 and State Route 16 as it traverses a grade of 2.85 percent—among the steepest of any passenger railway in the United States.[29][37] The S Line curves south and passes through South Tacoma station before it enters the city of Lakewood. The tracks pass an auxiliary railyard for Sounder trains and turn southwest near McChord Field to reach the southern terminus of the S Line at Lakewood station.[29][38]

History

S Line

The S Line (formerly the South Line) began service with two round trip trains on September 18, 2000, with stops in Tacoma, Sumner and Auburn that terminated in Seattle. Puyallup and Kent stations were added February 5, 2001, with Tukwila being added March 12, 2001. There are currently thirteen round trips on the S Line, with three operating in the reverse commute direction.[39]

In July 2010, Sound Transit reached a new agreement with BNSF, valued at $185 million, which grants Sound Transit permanent access to the S Line corridor, as well as allowing four more daily round trips to begin, starting in 2012 and continuing through 2016.[40]

On October 8, 2012, the extension to South Tacoma and Lakewood stations was inaugurated, with five daily round trips, all of which are in the peak direction, serving the new stations.[41] In September 2016, a mid-day round trip was added between Lakewood and Seattle.[42] In September 2017, two additional round trips were added, bringing the total to eight daily round trips servicing the Lakewood extension.[43][39]

The average weekday ridership in 2010 on the S Line was 8,300, down 7% from 2009 due to continued low employment in Downtown Seattle. Since then the average ridership has increased and as of October 2015 stood at 14,500 per day.[44] In 2019, S Line ridership was 16,419 per day.[45]

N Line

In May 2003, Sound Transit agreed to a $250 million lease arrangement with BNSF to use its Everett-to-Seattle tracks for 100 years. On December 17, 2003, the Sound Transit board approved a modified agreement that gave it a perpetual right to use the Everett-Seattle tracks for $258 million.[46]

The 35-mile (56 km) Everett-to-Seattle N line (formerly North Line) started with a Seahawks game train on December 21, 2003. Regular service started on December 22 with one morning train to Seattle and one evening train back. A second round trip train was added on June 6, 2005, to help increase ridership, a third was added in September 2007. In September 2008, an additional train was added to the line, bringing the total number to four round trips in the peak direction. On May 31, 2008, service to Mukilteo station began. There are currently three stops along the N Line: Edmonds, Mukilteo, and Everett.[47][48]

Weekday ridership on the N Line was roughly 1,100 in 2010[49] and was about 1,561 in the first quarter of 2016.[50] Trains on the N Line have been prone to frequent cancellation due to mudslides throughout its history,[51] though WSDOT has[when?] begun construction to remedy the problem.[52]

Future expansion

 
The future terminus of the S Line at DuPont station

Sound Transit plans to add additional S Line stations at Tillicum and DuPont. The track has already been constructed by Sound Transit with funding from WSDOT as part of the Point Defiance Bypass project. Funding for constructing the two stations was approved in the 2016 Sound Transit 3 ballot measure and is expected to cost $300 million. It was originally scheduled to open in 2036, but was delayed to 2045 due to a systemwide funding gap caused by increased planning costs.[53][54] The Tillicum station is planned to be located near the intersection of Interstate 5 and Berkeley Street Southwest, adjacent to Joint Base Lewis–McChord. The terminus at DuPont station is planned to be located adjacent to an existing park and ride lot at Interstate 5 and Center Drive.[55]

In addition, Sound Transit plans to extend station platform lengths on the S Line to accommodate trains up to ten cars in length, up from the current seven, and increase service.[56] Both programs were included in the Sound Transit 3 ballot measure and were originally scheduled to be fully completed by 2036, but were also delayed by the systemwide funding gap and subsequent realignment of projects. Platform extensions are scheduled to be complete by 2036, while additional trips on the S Line are scheduled to be implemented by 2046.[57][58]

Service and operations

As of 2017, schedules serve the traditional peak commutes, with most trains running inbound to Seattle in the morning and outbound in the afternoon. Three daily round-trips run the reverse commute to and from Tacoma.[39] Additional Sounder trains operate on some Saturdays and Sundays for travel to and from Seahawks and Sounders games at Lumen Field and Mariners games at T-Mobile Park. Both stadiums are a short walk from King Street Station.

Fares

Sounder operates using a proof-of-payment fare system and uses distance-based fares; adult fares range from $3.25 to $5.75.[59] Passengers are required to purchase a paper ticket, use a mobile ticket, or tap their ORCA card (and receive a valid permit to travel) before boarding trains. Sound Transit fare inspectors or police officers randomly board trains and check for valid proof-of-payment, issuing warnings or fines to passengers without valid proof-of-payment. Passengers using ORCA cards are charged the maximum fare from the station they are traveling from and are issued a permit to travel when they tap before boarding and, if necessary, receive a refund when they tap after boarding. Discounted fares are offered for seniors and the disabled, and low-income riders qualifying for the ORCA Lift program.[60] Passengers under the age of 19 ride for free.

Additionally, Sound Transit partners with Amtrak Cascades to allow riders on the N Line corridor to use the two trains per day that Amtrak Cascades operates to Bellingham, WA and Vancouver, BC through the RailPlus program. This allows commuters to use the Sounder fare structure between Everett and Seattle. The program is available only to riders who use monthly passes. The Amtrak Cascades trains do not stop at Mukilteo nor does Amtrak's Empire Builder from Chicago, Illinois.

During the COVID-19 pandemic in 2020, fare collection for all Sound Transit services was suspended from March 21 to June 1.[61] Fares on Link and Sounder were reintroduced on June 1 with a discounted rate of $2 for non-ORCA users on Sounder.[62]
