A large tree that had fallen onto the tracks caused a San Francisco Bay Area commuter train to derail Monday night, in an incident that sent nine passengers to the hospital — four of them with serious injuries.
The train, Altamont Corridor Express (ACE) No. 10, was traveling from San Jose to Stockton, Calif., when it went off the tracks Monday night. The derailment came after hours of sustained rains.
