A small dog can’t ride Amtrak when the dog and carrier together weigh more than 20 pounds, when the trip runs longer than 7 hours, or when you book a seat class that excludes pets. Amtrak’s carry-on pet rule allows one cat or dog per customer, in a carrier, on trips up to 7 hours on most routes. Each limit has a catch that holiday travelers often miss.
Amtrak has reported more than 1.2 million riders during a single Thanksgiving season, and Eliot Hamlisch, Amtrak Executive Vice President and Chief Commercial Officer, describes the train as “a comfortable, convenient alternative to congested highways and crowded airports all year round.” For an owner who would rather not fly a small dog, the train looks like the easy answer, but the Amtrak rules decide.
Why can a small dog still be over Amtrak’s 20-pound limit?
A small dog can be over the limit because Amtrak counts the dog and the carrier together. The Amtrak “Pets on Trains” page sets a “20-pound limit (combined weight of pet and carrier).” A dog close to 20 pounds alone will not qualify once the carrier is added.
The safest check is to weigh the dog inside the packed carrier at home. Amtrak also caps carrier size at 19 inches long, 14 inches wide and 10.5 inches high. Inside that space, Amtrak requires that the pet “be able to sit, lie down and remain entirely inside without touching the sides of the carrier.” A small dog who is under 20 pounds but too long to lie down in a 19-inch carrier still fails the Amtrak carrier rule.
Which Amtrak trains and seats don’t allow pets?
Pets ride only in Coach and Acela Business Class. Amtrak excludes pets from Acela First Class seating, First Class private rooms, non-Acela Business Class, food service cars and other accommodations. AARP’s travel guide states the same point in plainer words: “Pets also are not allowed in first class, sleeper cars and non-Acela business class.” An overnight trip in a private room is therefore out for a small dog, even before the time limit applies.
Several Amtrak services are excluded outright. Amtrak lists Auto Train, Gold Runner and Amtrak Connection services, and travel with pets in Canada is not available on the Adirondack, Maple Leaf and Amtrak Cascades. On Keystone and Pennsylvanian trains, pets cannot sit in the Quiet Car. On some routes, including Amtrak Cascades, Hiawatha and Wolverine, Amtrak assigns a specific Coach car for passengers with pets.
Why does the 7-hour cap rule out so many holiday trips?
The 7-hour cap rules out many holiday trips because Amtrak counts total travel time, transfers included. Amtrak allows pets “only on trips up to 7 hours on most routes,” and a reservation with a pet is capped at seven hours of total travel time on a multi-segment trip. AARP confirms that the seven hours “includes transfer time.”
A route with two short legs and a long wait between them can break the Amtrak limit, so count from the first departure to the final arrival. Pet fees also apply per travel segment and “vary by route,” so a connection adds cost as well as time. Amtrak shows the pet fee in the price summary at booking.
Does an Amtrak pet carrier go under the seat like on a plane?
No, an Amtrak pet carrier goes under your own seat, not the seat ahead. Amtrak tells passengers to place the carrier “under your seat (not under the seat in front of you).” The one exception Amtrak lists is Amtrak Cascades, where the carrier may go on the floor in front of the seat next to you.
Airlines work the other way. Delta states that “the kennel must fit fully underneath the seat directly in front of you,” and American Airlines says the pet must stay in its carrier under the seat in front of you for the entire flight. On Amtrak, the carrier also counts as one piece of carry-on baggage.
Can an emotional support dog skip Amtrak’s pet rules?
No, an emotional support dog follows the same rules as any pet on Amtrak. The Amtrak service animal page states: “An emotional support animal is not a service animal under DOT regulations and is subject to the same requirements as a pet.” Amtrak applies that rule to the carry-on pet guidelines as a whole, so the 20-pound and 7-hour limits both apply.
In practice, an emotional support dog needs a pet reservation, a carrier inside the size limit and a combined weight under 20 pounds. An emotional support dog also counts toward Amtrak’s limit of one pet per customer, and its carrier still goes under your own seat rather than the seat in front of you.
What can get a small dog turned away at the station?
Missing paperwork, a late check-in or disruptive behavior can all stop a small dog at the station. Amtrak requires a signed Pet Release and Indemnification Agreement for each travel segment, available at the end of booking, under “My Trip” or in the Amtrak app. At staffed stations, passengers with pets check in at the ticket office 45 minutes before departure so agents can validate eligibility and paperwork.
The pet must be at least eight weeks old and “odorless, harmless, not disruptive,” and must need no attention during the trip. Amtrak may refuse or remove a pet that does not meet those conditions, and the pet must travel with a person rather than as checked baggage. Passengers also certify that the pet is up to date on all vaccinations. Amtrak states plainly that it “does not accept liability for the health and well-being of pets,” so consult your veterinarian before a long trip if you are unsure whether your dog is ready for train travel.
How do Amtrak’s rules compare with flying a small dog?
Amtrak is stricter on weight and trip length, while airlines expect a smaller carrier footprint and charge a fixed fee.
| Rule | Amtrak | Delta / American |
|---|---|---|
| Weight cap | 20 lb with carrier | No general cap |
| Carrier size | 19 x 14 x 10.5 in | 18 x 11 x 11 in soft |
| Carrier spot | Under your seat | Seat in front |
| Time limit | 7 h with transfers | Most flights to 12 h (AA) |
| Fee | Varies by route | $150 each way |
American Airlines has no general weight limit, but on its three-cabin Airbus A321T the pet and carrier together must not exceed 20 pounds. Delta does not publish one fixed kennel size and recommends a soft-sided kennel of 18 by 11 by 11 inches because the maximum depends on the aircraft. Both airlines and Amtrak require a pet to be at least 8 weeks old for domestic travel.
When Amtrak opened weekday Acela trains to pets, Caroline Decker, Amtrak Vice President for the Northeast Corridor Service Line, said: “We are delighted to expand our pet program to weekday Acela trains.” Amtrak reported at that time that more than 174,300 pets and their human companions had ridden under the program.
Frequently asked questions
Can two small dogs travel with one passenger on Amtrak?
No. Amtrak limits reservations to one pet per customer and one pet per carrier, so two dogs need two travelling customers.
Can a small dog ride in an Amtrak sleeper room?
No. Amtrak excludes First Class private rooms, and pet trips are also capped at 7 hours of total travel time.
Can a dog travel as checked baggage on Amtrak?
No. Amtrak states that pets cannot travel as checked baggage and must travel with a person.
What happens to a pet if a train is disrupted?
If passengers need shelter, Amtrak says it will make reasonable efforts to find pet-friendly hotels but cannot guarantee them. Check Amtrak’s current pet policy before travel.
