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.<br />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.<br />They had initially said about 200,000 liters of acid was on board.<br />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.
