How to change amtrak reservations
Change your ticket delivery method.
You can choose to have your tickets sent by mail or arrange to have them ready for pick-up at an amtrak kiosk, amtrak station, or amtrak vending machine.
Modify the times or dates of your reservation based on your new traveling plans.
There are no penalty fees for changing a reservation. You may be required to pay the difference in cost if your new, updated ticket has a higher rate.
