CIMARRON — An Amtrak train carrying more than 140 people derailed in rural Kansas early Monday, moments after an engineer noticed a significant bend in a rail and applied the emergency brakes, authorities said.
At least 32 people were hurt, two of them critically, authorities said.
A federal transportation official said the investigation would focus on the condition of the rails. Local authorities said they were checking whether a vehicle crash may have damaged the track before the accident.
