Derailed train in Australia had more than 200,000 gallons of acid on board

The freight train was carrying sulfuric acid when it came off the tracks in northern Queensland.

Story highlights

  • Police revise up the amount of acid on board to over 800,000 liters
  • At least one freight car has probably ruptured and leaked, police say
  • The exclusion zone around the crash site is set to stay in place for days

(CNN)The train that derailed in northern Australia over the weekend was carrying more than four times as much sulfuric acid as previously announced, police said Tuesday.

The freight train had roughly 819,000 liters (216,000 gallons) of the highly corrosive acid on board when it came off the tracks Sunday morning in a remote area of northern Queensland, state police said. They had initially said about 200,000 liters of acid was on board.
    Officials believe that at least one of the freight cars has probably ruptured, which means as much as 31,500 liters of acid could have leaked out, according to a police statement.

    Exclusion zone set up around site

    Authorities have declared an emergency and set up a 2-kilometer (1.2-mile) exclusion zone around the crash site. The exclusion zone is expected to remain in place until at least Thursday.
    The train's locomotive ended up on its side, and all 26 freight cars it was pulling derailed, according to authorities.
    Photos from the scene showed the jumble of cars sprawled across mangled tracks and waterlogged terrain.
    Three men who were aboard the train were believed to have suffered minor injuries, police said.

    Weather, floods hampering response

    A nearby highway was closed as a result of the exclusion zone and flooding in the area.
    It isn't clear what exactly caused the derailment about 20 kilometers (12.4 miles) east of the town of Julia Creek.
    Police Inspector Trevor Kidd told the Australian Broadcasting Corporation on Monday that there was soft mud at the crash site.
    "You have to take into account it's remote, it's impacted heavily by weather, access is quite difficult, and these are the challenges the responders are facing at the moment," he said.
    Initial testing by environmental officials suggested that the nearby Horse Creek waterway hasn't been polluted by the acid spill, police said Tuesday.
