One train rear-ended another at about 2 a.m. EDT on the EPCOT track near the Disney World parking lot as people were leaving the park following a Fourth of July fireworks show, witnesses told local cable-TV news channel Central Florida News 13.
Bo Jones, deputy chief for Reedy Creek Fire Department, says one train operator died at the scene of the crash.
The other train operator was not injured, but was taken to a hospital because he was emotionally shaken. Five park guests were treated at the scene.
"Today, we mourn the loss of our fellow Cast Member. Our hearts go out to his family and to those who have lost a friend and co-worker," read a statement from Walt Disney World Vice President of Public Affairs Mike Griffin.
