NTSB investigators are on the scene of a Kansas train derailment looking into what caused the accident this morning that hurt several passengers.

FOX's Gurnal Scott reports:

It's being called "a significant bend" in a rail that forced an engineer to suddenly brake causing eight cars of an Amtrak train to leave the track injuring 32 people, two of them critically.

That "bend" is what the NTSB is focused on wondering if a prior accident on the track caused the deformity. So far the damage doesn't appear intentional.

Sheriff's deputies working with the federal agency were closely examining tire tracks leading up to the damaged rail in Cimarron, Kansas, a small community west of Wichita.

The train was traveling from L.A. to Chicago when it derailed.
