Jon Tester of Montana added an amendment to the Surface Transportation Investment Act of 2021 which would require the Department of Transportation (not Amtrak itself) to evaluate daily service on all less frequent long-distance trains, meaning the Sunset Limited and Cardinal. The bill passed the Senate Commerce Committee with bipartisan support, and was later rolled into President Biden's Infrastructure Investment and Jobs Act, which Congress passed on November 5, 2021. The report must be delivered to Congress within two years.
