A fatal heart attack on Metrolink prompts calls for defibrillators on commuter trains
Early on a recent Monday, a Metrolink train bound for downtown Los Angeles screeched to an unexpected stop in Buena Park.
The train had struck debris on the tracks earlier that morning, and the train’s air conditioning and electricity had just shut off, a conductor told passengers. The cars grew stuffier and hotter as the train baked in the morning sun.
