Claim
It runs for 20 hours per day on weekdays and Saturdays, with headways as low as six minutes during peak hours, and reduced 18-hour service on Sundays and holidays.
Correction

This service description is outdated. Sound Transit says that after the March 28, 2026 service change, 1 Line/2 Line service runs about 5 a.m. to 12 a.m. seven days a week, and 1 Line peak service is every 8 minutes, not 6.

Full reasoning

This sentence no longer matches Sound Transit’s current published service pattern.

  • In Sound Transit’s March 28, 2026 Crosslake Connection opening release, the agency states: “Service on both the 1 Line and 2 Line will run from about 5 a.m. to 12 a.m. seven days a week.” That directly contradicts the article’s claim that the 1 Line still runs until 1:00 a.m. Monday–Saturday and only 6:00 a.m. to midnight on Sundays/holidays.
  • Sound Transit’s official service announcements also describe 1 Line peak service as every 8 minutes, not every 6 minutes. For example, the agency’s August 28, 2025 Federal Way opening announcement says: “During peak hours, trains will operate every eight minutes.”
  • On the shared Lynnwood–International District/Chinatown segment, the March 28, 2026 release says combined 1/2 Line service arrives every four to five minutes, which is also inconsistent with describing the 1 Line itself as having six-minute peak headways.

So the article’s current-tense service summary is outdated on both service span and peak frequency.

  • Link light rail opens across Lake Washington | Sound Transit

    Service on both the 1 Line and 2 Line will run from about 5 a.m. to 12 a.m. seven days a week. Trains will run approximately every eight minutes at peak at the new stations, and between 10-15 minutes the rest of the day. Between Lynnwood City Center and International District/Chinatown stations, combined 1- and 2-Line headways will mean trains arrive every four to five minutes.

Claim
Sound Transit uses proof-of-payment to verify passenger fares, employing fare ambassadors and transit police to conduct random inspections.
Correction

This misstates who checks fares. Sound Transit says Fare Ambassadors—not transit police—are the fare-compliance staff who inspect proof of payment.

Full reasoning

Sound Transit’s current fare-enforcement materials assign fare inspection to Fare Ambassadors, not transit police.

  • On Sound Transit’s official Fare ambassadors page, the agency says Fare Ambassadors “Check fares” and “systematically review paid passenger fares on Sounder, 1 Line, 2 Line, and T Line trains.”
  • On Sound Transit’s personnel and security staff page, transit police are described separately as officers who “routinely patrol Link trains and stations to create a safe environment” and monitor car, bicycle and pedestrian traffic. That page identifies Fare Ambassadors as the staff who inspect and educate riders about fares.
  • Sound Transit also announced in 2021 that Fare Ambassadors would “replace fare enforcement officers” as part of the new fare-checking program.

Because Sound Transit’s own current documentation assigns fare inspections to Fare Ambassadors and describes transit police in a safety/patrol role, the article’s claim that Sound Transit uses “fare ambassadors and transit police to conduct random inspections” is inaccurate.

Claim
1 Line trains are operated and maintained by King County Metro under a contract with Sound Transit that was renewed in 2019 and is set to expire at the end of 2023.
Correction

The contract-expiration date here is wrong. Sound Transit’s 2024 annual report says the current Link light-rail agreement with King County expires on December 31, 2025, not at the end of 2023.

Full reasoning

The statement’s contract-expiration date is outdated.

  • Sound Transit’s 2024 annual report says: “Link Light Rail— Sound Transit contracts with King County Metro for the operation and maintenance of its light rail service… The current agreement with King County is for 2 years, expiring December 31, 2025.” That directly contradicts the article’s statement that the contract “is set to expire at the end of 2023.”
  • The 2019 joint Sound Transit/King County Metro announcement about the renewed agreement said that the new agreement would continue service through Dec. 31, 2023, and potentially through December 2029. So even the 2019 renewal materials did not support presenting 2023 as the final fixed endpoint in a 2026 article.

In short: King County Metro still operates the line, but the article’s stated expiration date is no longer correct.

Claim
1 Line trains run 20 hours per day from Monday to Saturday, from 5:00 am to 1:00 am, and 18 hours on Sundays and federal holidays, from 6:00 am to midnight.
Correction

This schedule is outdated. Sound Transit says that since the March 28, 2026 service change, 1 Line/2 Line service runs about 5 a.m. to 12 a.m. seven days a week.

Full reasoning

Sound Transit’s current published schedule no longer matches this sentence.

In the agency’s March 28, 2026 Crosslake Connection opening release, Sound Transit states: “Service on both the 1 Line and 2 Line will run from about 5 a.m. to 12 a.m. seven days a week.” That contradicts the article’s claim that 1 Line service still runs until 1:00 a.m. Monday–Saturday and starts later on Sundays.

Because the article uses present tense to describe current service, this older operating span is no longer accurate after the March 2026 network change.
