The extension builds on the Metro A Line’s status as the world’s longest light rail line, now spanning 57.6 miles
Los Angeles County transportation officials on Thursday celebrated the opening of a long-awaited extension of the Metro A Line, restoring local rail service to parts of the San Gabriel Valley for the first time in more than 70 years.
The 9.1-mile project, which cost $1.5 billion, extends the light rail line from Azusa to Pomona, adding stations in Glendora, San Dimas, La Verne and Pomona. The last passenger rail service in the corridor was provided by the Pacific Electric Railway, which ended operations in 1951.
The extension builds on the Metro A Line’s status as the world’s longest light rail line, now spanning 57.6 miles. The route connects riders to destinations including 19 nearby colleges and universities, the Pomona Fairplex, downtown districts, parks, museums, hospitals and shopping areas.
The project is also the ninth completed under Metro’s “Twenty-Eight by ’28” initiative, which aims to deliver major transportation improvements across Los Angeles County ahead of the 2028 Olympic and Paralympic Games.
