What You Can Do

trash-300pxPlease join the many Caltrain riders who help make sure that our waterways stay clean. When at stations, throw your trash in one of the bins provided. Caltrain has an extensive recycling program that helps separate trash from compost and recyclables. Read more about our recycling program HERE.

Even before reaching the bay, trash can cause harm by clogging storm sewers and streams. Many communities host clean-up events with volunteers collecting trash in creeks and along shorelines. For more information on participating in an upcoming event, click on one of the counties: San Francisco,  San Mateo, Santa Clara.

You can help further by using less toxic options at home to reduce negative impacts on the environment. Please dispose of chemicals, including pesticides, and motor oil at properly licensed disposal facilities. Many municipalities offer free disposal options and information on how to properly dispose of all sorts of household wastes.Visit webpages for these counties where Caltrain operates to find out more: San Francisco,  San Mateo County, Santa Clara County.
