Los Angeles Metro has opened a 14.6 km extension of Line A, making it the world’s longest light rail line at 92.7 km with 48 stations. The $1.5 billion project adds four new stops, including Pomona North, which links to Metrolink services. Operating every 8 minutes, the extension enhances connectivity, cuts commute times, and supports sustainability goals while setting the stage for future expansion to Montclair.
