Louisville Metro Government has paid more than $525,000 to settle 23 claims stemming from a train derailment at the Louisville Zoo in 2009. The city has spent another $176,000 in legal fees in defending the lawsuits. The accident sent 22 people to hospitals after the open-air train flipped onto its side. So far this month, the city has paid $150,000 to settle seven claims, according to The Courier-Journal of Louisville. The newspaper cited records provided under the Kentucky Open Records Act. Six more claims are pending from those who aboard the train.
