MAX, Neb. (AP) — Amtrak says a train carrying about 175 passengers between Chicago and San Francisco has derailed in southwest Nebraska.

Spokesman Marc Magliari says the California Zephyr derailed around 8 a.m. Friday near Max, not far from the state’s borders with Kansas and Colorado.

Magliari says there have been no reports of serious injuries but can’t say for sure whether anyone aboard was hurt.

He says it appears the train struck a vehicle on the tracks. He didn’t know what kind of vehicle was hit.
