Louisville, Ky. (WHAS11) - There are new questions about who should be held liable for the passenger train crash at the Louisville Zoo in 2009.
An appelate court has ruled Zoo Director John Walczack isn't immune as a metro government employee-- and could be held liable for the crash.
Attorneys for some of the families injured are now calling for changes in the Kentucky immunity law.
The train was going too fast around a curve when it overturned with 29 people on board, and 22 people were injured.
The zoo has since purchased a new train.
The County Attorney said they are still deciding if they'll appeal this decision to the Kentucky Suprme Court.
