This photo provided by Portland, Ore., Fire & Rescue shows a sinkhole in Portland, Ore., on Tuesday, Feb. 18, 2014. A Portland fire official says a woman and her dog have been rescued unharmed after falling into the six-meter-deep sinkhole that opened up in her backyard. Portland Fire & Rescue Lt. Rich Chatman says the woman in her 30s was trying to find her small poodle mix Tuesday night in her dark Portland backyard when she fell into a sinkhole. A neighbor who heard her cries for help called 911. Fire crews used rope and ground ladders to rescue them. Chatman says fire officials at the scene were amazed that both escaped unhurt. The spokesman says a neighbor who shares a property line said both homeowners had been required to do some recent work on their sewage system. (AP Photo/Portland, Ore., Fire & Rescue)

FILE -This Sept. 12, 2008 file photo, rescue personnel work at the scene of a train crash in Los Angeles. Southern California’s commuter train network has become an early adopter of crash-avoidance technology that its own horrific accident helped make mandatory. Metrolink quietly rolled out a train Monday, Feb. 17, 2014, equipped with “positive train control,” a system that lets dispatchers halt engines remotely if they speed or blow through stop signals. Congress mandated the technology after a Metrolink engineer ran a red light while he was texting and crashed head-on with a freight train in 2008. (AP Photo/Hector Mata, File)
