On Sunday night, Goyo Alvarez stood on a BART platform with his mom, Julie. They were inches away from the rushing trains — but the Alvarezes weren’t there to board one. Instead, they were listening for Goyo’s voice, which has been echoing across the Millbrae station every half hour of every day for Autism Awareness Month this April.

“Hey everybody, my name is Goyo and I love trains and BART,” said the recording, which was made by the 12-year-old Redwood City boy last month. “Please stand safely behind the yellow platform edge tiles as the train arrives. It scares the train operator if you are too close, and it is not safe.”
