In 2018, Caltrain switched to 100% renewable energy, but in our ongoing commitment to sustainability we recently converted the existing lights at 20 passenger stations to energy-efficient LEDs. This saves the equivalent electricity consumption of approximately 1,600 U.S. residential homes per year. Retrofitting more than 2,700 lights also saves Caltrain over $250,000 in annual electricity costs. The exterior light casings remain the same, as well as the overall illumination; but with this project, Caltrain continues in its efforts to be a cleaner and greener service for the communities it serves.
