Louisville has reached a $6 million settlement with five people injured in a 2009 derailing of a small train that carries families around the city’s zoo.

The open-air, small-engine train was carrying about 30 passengers when it went off the rails near the Louisville Zoo’s gorilla exhibit. Several children were on board.

The Jefferson County attorney’s office announced the settlement Tuesday. The office did not name any parties to the lawsuit but said in a release that all legal actions related to the June 1, 2009 crash are complete. The city had previously settled with 26 other riders for a total of $662,499.

Since the crash, the Louisville Zoo has invested in new equipment and training to improve train safety. The zoo resumed train tours in 2013.
