A little before 6:30 p.m. last night, two F-line streetcars rammed into each other at The Embarcadero and Washington, sending both operators and four passengers to the hospital with non-life-threatening injuries. Other wounded passengers were treated on the spot. According to Judson True, SFMTA spokesking, "The collision is under investigation." Anyone with raw footage of the crash, like last June's T-Line crash over at AT&T Park, is urged to post it right-quick for our temporary amusement. (SFGate)
