Buckeye would become rail line’s western anchor in Phoenix-Tucson passenger rail plan

A proposed passenger rail line that would stretch between Tucson and Buckeye is inching closer to reality, and local officials say the potential economic and transit impacts for the West Valley could be transformative.

The Arizona Department of Transportation announced today that it cleared a key federal hurdle that allows it to begin developing a formal service plan for the long-discussed intercity rail corridor. The project, which would span roughly 160 miles, would make Buckeye the western terminus — positioning the fast-growing city as a regional transportation hub.

The Federal Railroad Administration has approved ADOT’s initial scope, schedule and $10.6 million budget under the federal Corridor Identification and Development Program. Once a grant is finalized in the coming weeks, work can begin on the Service Development Plan, a major step that will define station locations, infrastructure needs, ridership forecasts and long-term costs.

“This is a big step forward for Arizona,” said Gov. Katie Hobbs. “I am committed to creating a bright transportation future for our state that fosters economic growth, creates jobs and expands transit opportunities for working people and families.”

Buckeye leaders have long advocated for stronger regional transit connections, particularly as the city continues to experience explosive population growth. Being named as the endpoint of a Tucson rail line could be a logistical and economic win.

While specific station locations have not yet been finalized, Buckeye is expected to play a critical role in the corridor. As part of the upcoming service plan, ADOT will analyze travel data, access to schools and jobs, and technical feasibility to determine where rail stations would go — and how many are needed.

ADOT Director Jennifer Toth emphasized the broader benefits of a Phoenix-Tucson rail line, calling it “an important addition to transportation options” that could enhance mobility for both rural communities and rapidly expanding suburbs like Buckeye.

Completing the service plan is expected to take two to three years. If successful, it would pave the way for the final planning phase: a Tier 2 environmental and engineering study under the National Environmental Policy Act, which would require another federal grant and a 20% state funding match.

The rail corridor was formally accepted into the federal program in late 2023. While there’s currently no funding allocated for actual construction, ADOT and its partners — including the Governor’s Office and regional planning organizations — are exploring future funding options, including local, state and federal sources.

Gov. Hobbs has already earmarked $3.5 million to support the planning process.

For Buckeye residents, the news signals growing recognition of the city’s strategic location and potential as a key link in statewide infrastructure development.
