You may bring your own food and beverages onboard for consumption at your seat or private Sleeping Car accommodations. However, you can only consume food and beverages purchased in Dining and Lounge Cars in those cars. Personal food and beverages are allowed in the upper level of Superliner Sightseer Lounges.

Yes, you can drink at your seat on Amtrak, but the rules regarding where the alcohol came from are very strict. You are permitted to consume alcoholic beverages at your seat (in Coach, Business, or First Class) only if they were purchased from the onboard Café or Dining Car. Federal regulations and Amtrak policy strictly prohibit the consumption of your "private stock" (alcohol you brought from home) in any public area of the train, including your seat, the Lounge Car, or the Café Car. The only exception to this is if you are traveling in a Private Sleeping Car (Roomette or Bedroom); in these private accommodations, you are allowed to bring and consume your own alcohol. If you are caught drinking your own alcohol in the public coach cars, the conductor has the authority to confiscate the beverage or, in extreme cases, remove you from the train at the next station for a violation of federal rules. This policy ensures that the airline-style "liquor license" protocols are maintained and that the crew can monitor the level of intoxication for the safety of all passengers.
