Hi I am planning to travel with Amtrak from Chicago to Los Angeles on Southwest Chief route.On the newspaper I read that Border Patrol shows up in trains and checks people's passports to see if they are legal within 100 miles of the border. When I checked the map I noticed that Southwest Chief doesn't really come close to the border. Should I bring my passport with me or does border patrol not come to Southwest Chief trains since it's more than 100 miles away from the border? Thanks.

And their response:

Dear Customer,

Thank you for contacting us.

Border patrol does not effect the Southwest Chief.

I hope this information is helpful.
