What stands out about Tonti Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The community of Tonti was named in honor of Henri de Tonti, an early Italian/French explorer of Illinois.
On June 10, 1971, Tonti was the site of the 1971 Salem, Illinois, derailment which was a derailment of Amtrak's City of New Orleans passenger train. It is sometimes referred to as the Tonti derailment. An investigation by the National Transportation Safety Board (NTSB) found that the derailment was caused by a false flange on a flat wheel caused by a seized axle bearing. The crash killed 11 people and injured 163. It was Amtrak's first train crash.
