Nighttime active train testing is now underway, with crews operating multiple light rail vehicles on their own power to test all elements of the new light rail system. Testing will be underway through the end of 2024. Currently, train testing is taking place nightly between San Dimas and Pomona, but testing will be expanded to Glendora in the coming weeks. Please be aware and follow all safety rules near the corridor. For more information on the active train testing, which will continue through December 31, click here for the notice.
