The Gold Line extension project, linking Glendora to Pomona, is currently in its final testing phase. We spoke with representatives from the Foothill Gold Line Construction Authority to get the latest updates on this critical infrastructure development ahead of the 2028 Los Angeles Olympics.
As of late October, the extension has surpassed 90% completion, with a target of wrapping up construction by the first week of January 2025. During this final phase, crews are busy finalizing testing on trains while also completing work on four stations—Glendora, San Dimas, La Verne, and Pomona—and related parking facilities. This includes the installation of safety warning systems and artistic decorations designed to enhance the stations’ appeal.
The extension spans 9.1 miles across four cities, and while most test runs are scheduled for nighttime, there may be intermittent daytime sessions as well. Officials are urging the public to remain vigilant and avoid the testing areas, as multiple trains will be operating at high speeds through densely populated communities and commercial districts.
Initiated in the spring of 2020 with a budget of $210 million, the Gold Line project is a critical part of a larger 12.3-mile upgrade that will connect Glendora to Pomona and eventually to Montclair. This effort includes the construction and renovation of 24 highway bridges and 26 new surface road interchanges, representing the fourth-largest construction initiative in Los Angeles County. Each of the six station designs reflects local culture and characteristics.
Glendora Station, the first in the extension, is located at the intersection of Vermont Avenue and W. Glendora Avenue. Its design, themed “A Slice of Sunshine,” incorporates local imagery, full of vibrant colors created through specially made tiles, including oranges and bougainvillea. Commuters can travel from Glendora to Pasadena in just 22 minutes and to Los Angeles Union Station in 51 minutes.
San Dimas Station, near San Dimas Avenue and Arrow Highway, embraces the theme “Sense of Place,” highlighted by a sculpture entitled “Walking Sticks,” which showcases the area’s parks and trails. It provides a 27-minute ride to Pasadena and a 56-minute commute to Los Angeles.
La Verne Station, situated at the intersection of North Arrow Highway and East E Street, features designs that resemble multiple variations of the Eiffel Tower and incorporates motifs of orange trees and water patterns. Passengers will travel to Pasadena in 31 minutes and to Los Angeles Union Station in 60 minutes.
The Pomona Station, designed to have the most tracks, will feature inspirational quotes and life messages embedded in the station’s steps, cultivating a sense of community. Anticipated travel times from Pomona to Pasadena will be around 33 minutes and to Los Angeles will take approximately 62 minutes.
Claremont Station will be located at the intersection of East Indian Hill and West College Avenue, nearly identical to the current train station location. A unique feature of this station will be a three-dimensional pillar displaying the name “Claremont” in hundreds of languages, alongside tiles representing various fields such as science, art, and education. Montclair Station will be the final stop in this extension, featuring ample parking with 1,600 spaces.
Once completed, the Gold Line will facilitate over 200 daily light rail trips, accommodating between 400 and 600 passengers per train.
