A collision of two streetcars today at a municipal station in San Francisco left 44 people injured, three seriously, the San Francisco Chronicle reports. The driver who rear-ended another train was hurt the worst; the crash shattered the front window of the train and crumpled its nose. "This is probably one of the largest we've ever seen," a deputy fire chief said of the number of injuries.
"It sounded like a bomb or an explosion, we looked up and said, 'What the heck was that,'" one witness said. "There was this huge plume of dark smoke that came out from the back of the street car" that was hit.
