The Foothill Gold Line Phase 2B project further extends the Metro A Line (formerly the Gold Line) from the previous terminus at APU/Citrus College Station onward through Glendora, San Dimas, La Verne, finally reaching Pomona. The extension added about 9 miles and four stations which, when reconfigured with the Regional Connector project, makes the A line the longest light-rail line in the world at over 57 miles. The project opened to the public on-time and on-budget on September 19, 2025.
B&C Transit Inc. provided detailed design of both train control and communications systems for the project which required extensive coordination with other contractors and the agency. B&C Transit Inc. then procured, assembled, wired, tested, and fully configured all of the systems equipment. This included an innovative railway intrusion detection system based on infrared thermal cameras installed at strategic locations that were configured to detect foreign objects entering the right-of-way that could impact system operation.
