Metro will officially launch passenger service on the 9.1-mile A Line extension from Glendora to Pomona on Friday, September 19, 2025, expanding regional rail service across the San Gabriel Valley.
This $1.5 billion project adds four new stations in Glendora, San Dimas, La Verne/Fairplex, and Pomona North, offering Pasadena-area riders direct access to key destinations such as universities, hospitals, shopping centers, and the Pomona Fairplex, which will host cricket events during the 2028 Olympics.
New Metro Connections and Transit Access
The Pomona North Station provides a direct transfer to Metrolink’s San Bernardino Line, opening a vital route into the Inland Empire. Once operational, the A Line will stretch approximately 57.6 miles, making it the world’s longest light rail line, running from Pomona through Pasadena, downtown Los Angeles, and down to Long Beach.
Safety Training Ahead of Opening
Metro has conducted extensive emergency preparedness training in partnership with local law enforcement from Glendora, San Dimas, La Verne, Monrovia, Sierra Madre, and Claremont. Sessions focused on tactical rail car movement, platform entry and exit drills, and operational coordination to ensure safety once service begins.
Part of ‘Twenty‑Eight by ’28’ Initiative
This extension is a flagship project within Metro’s “Twenty‑Eight by ’28” initiative, aimed at expanding transit capacity ahead of the 2028 Olympic and Paralympic Games in Los Angeles.
Construction Timeline and Funding
The extension reached substantial completion on January 2025, and was delivered on time and within its $1.5 billion budget. Construction was managed by Kiewit‑Parsons (KPJV) under a major contract awarded in 2020, which included building 19 bridges, 21 at‑grade crossings, parking facilities for roughly 300 vehicles per station, decorative sound walls, and other infrastructure.
Primary project funding came from Measure M (2016 half‑cent sales tax), residual Measure R funds, and a significant CalSTA TIRCP state grant of nearly $300 million, supporting both construction and future phases toward Montclair.
Looking Ahead: Pomona to Montclair
Following the Pomona opening, Metro and the Foothill Gold Line Construction Authority will begin the next phase of the extension to Montclair. In March 2025, the Construction Authority Board canceled the previous design-build procurement after receiving a final bid from Kiewit that far exceeded available funding and cost estimates. The Authority is now pursuing a Construction Manager at Risk (CMAR) delivery method.
In June, the Authority began procurement to hire a designer and contractor. The design contract is expected to be awarded in November 2025, with a contractor selected in March 2026. Once construction begins, the segment to Claremont and Montclair is projected to take approximately four years to complete.
