Free Rides on California Clean Air Day


On Wednesday, October 4, 2023, we’re making it easy for you to take the train by offering free rides all day throughout our system in celebration of California Clean Air Day 

California Clean Air Day is an annual call to action for California residents to do what we can to improve air quality and protect public health. With motor exhaust being a leading cause of air pollution in Southern California, residents can take environmentally friendly steps to improve air quality and overall public health by using public transportation to decrease carbon emissions.  

To ride, simply get your free ticket for the day. People who have downloaded and verified their account on the Metrolink mobile app before October 2 will receive a free round-trip ticket to be used on October 4. The app is free to download on the Apple Store and Google Play. All mobile app tickets must be activated before boarding. For those who prefer a paper ticket, use the promotional code CLEANAIR23 on any Metrolink ticket machine to obtain your free ticket.
