WSBT-TV reports he says there are measurements to take, interviews to conduct and electronic data that needs to be analyzed before a determination of the cause can be made.
The Amtrak train was traveling from Chicago to Pontiac, north of Detroit, on Sunday when two of its locomotives and one or more coaches derailed. It happened near Niles, just north of the Indiana state line.
Amtrak says none of the injuries were considered serious or life-threatening. The train was carrying about 174 passengers and four crew members.
