Most trains allow dogs, but the rules depend on which railroad you're using and how big your dog is
You can bring your dog on many trains in the United States, but each railroad sets its own rules about size, number of dogs, and where your dog can sit. Some trains let small dogs ride free in a carrier; others charge a pet fare and allow larger dogs in designated cars. A few regional and commuter lines have different policies altogether. Before you book, you need to check the specific railroad's pet policy—not all trains treat dogs the same way.
The major U.S. railroads that carry passengers are Amtrak, regional commuter lines (like NJ Transit, SEPTA, and Caltrain), and some tourist or heritage railways. Each one publishes its pet rules online, and those rules are the only ones that matter for your trip. Calling ahead is the safest move if you're unsure or if your dog is close to a size limit.
Key Takeaways
- Amtrak allows one dog per passenger in a carrier on most routes, with a pet fee of around $25 to $30 per trip, though some trains do not allow pets at all.
- Commuter rail systems like NJ Transit, SEPTA, and Caltrain have their own pet policies—some allow small dogs free during off-peak hours, while others require carriers or charge fees.
- Your dog must stay in a carrier, crate, or on a leash in designated areas; loose dogs are not permitted on any major U.S. passenger train.
- Service dogs and emotional support animals have different rules and may not need a carrier, so you should contact the railroad directly if your dog has a working role.
Amtrak's pet policy and how it works
Amtrak allows one dog per passenger on most long-distance and regional routes, but not on all of them. The Northeast Regional, Palmetto, and Silver Service routes do not allow pets. On routes where pets are allowed, your dog must travel in a carrier, crate, or pet-specific travel bag that fits under your seat or in your lap. Amtrak does not provide kennels or special pet cars.
The pet fee is approximately $25 to $30 per one-way trip, depending on the route. You pay this fee when you book your ticket, not at the station. Your dog's carrier counts as a personal item, not a checked bag, so it does not take up your baggage allowance. Amtrak does not specify a weight limit, but the carrier itself must be small enough to fit under a standard train seat.
You are responsible for your dog's comfort and behavior during the trip. Bring water, a collapsible bowl, and any medications your dog needs. If your dog barks excessively or becomes disruptive, Amtrak staff can ask you to leave the train at the next stop.
Commuter rail systems and regional trains
Commuter railroads that serve major cities have their own pet policies, and they vary widely. NJ Transit allows small dogs in carriers on buses and trains, with no additional fee. SEPTA (Philadelphia) allows dogs in carriers on regional rail lines. Caltrain (San Francisco Bay Area) permits small dogs in carriers during off-peak hours at no charge. MTA (New York) allows small dogs in carriers on the Long Island Rail Road and Metro-North, also free.
The common thread is that your dog must be in a carrier or crate—these systems do not allow dogs to roam freely or sit on seats. "Small dog" usually means under 25 pounds, though some systems do not specify a weight and instead focus on whether the dog fits in a standard pet carrier. Check your local railroad's website or call their customer service line to confirm the current rules before you travel.
Some heritage and tourist railways, like the Cog Railway in New Hampshire or scenic mountain trains, allow leashed dogs in open-air cars or designated seating areas. These are exceptions to the carrier rule, but you should always ask when you book.
Service dogs and emotional support animals
Service dogs trained to perform specific tasks for people with disabilities are treated differently from pet dogs on trains. Amtrak and most commuter railroads allow service dogs to travel without a carrier and without an additional fee. You will need to show documentation that your dog is a trained service animal—usually a vest, ID card, or letter from a disability organization.
Emotional support animals (ESAs) are not the same as service dogs under federal law. ESAs do not have the same access rights on trains as service dogs do. Some railroads may allow an ESA in a carrier under their pet policy, but you should contact the railroad directly to ask. Do not assume an ESA will be treated the same way as a service dog.
What to bring and how to prepare your dog
Pack a collapsible water bowl, bottled water, and any medications your dog takes regularly. Bring waste bags and plan to use the restroom at stations if your trip is longer than a few hours. Some trains have longer stops that give you time to walk your dog on the platform, but do not count on it—check your specific train's schedule.
If your dog has never traveled by train, take a short trip first to see how they handle the noise, motion, and confined space. A anxious or aggressive dog can disrupt other passengers and may result in you being asked to leave the train. Consider talking to your veterinarian about calming supplements or medications if your dog gets very stressed during travel.
Arrive at the station early so you have time to get your dog settled before boarding. Keep your dog in the carrier or on a short leash while moving through the station and boarding the train. Once you are in your seat, keep your dog close and monitor their behavior throughout the trip.
Booking your ticket and what happens at the station
When you book an Amtrak ticket online or by phone, you will see a checkbox or option to add a pet. Select it and pay the pet fee at that time. The fee is non-refundable, so if your plans change, you lose the pet fee even if you get a refund for your ticket. Some Amtrak routes sell out pet spaces, so book early if you are traveling during peak season.
At the station, arrive at least 30 minutes before departure so you have time to check in and board without rushing. Tell the ticket agent that you have a dog so they know to seat you in an area where pets are allowed. Boarding usually happens in groups by car number, and staff will direct you to the right place.
Once on the train, keep your dog in the carrier or on a leash in your seat area. Do not leave your dog unattended, even for a short time. If you need to use the restroom or go to the dining car, take your dog with you or ask a travel companion to watch them.
What to do if your dog gets sick or injured during the trip
Train staff are not equipped to provide veterinary care. If your dog becomes ill or injured during travel, the train will stop at the next station and you may need to get off to find a veterinarian. For long trips, research veterinary clinics near major stops along your route so you know where to go if an emergency happens.
Bring a copy of your dog's vaccination records and any medical information in case you need to see a vet. If your dog has a chronic condition or takes medication, pack extra doses in case your trip is delayed. Travel insurance for pets is available from some companies and may cover unexpected veterinary costs, though it does not cover routine care.
Frequently Asked Questions
Can I take my dog in the dining car or observation car?
No. Your dog must stay in your assigned seat or sleeping car. You can leave your dog in your seat while you go to the dining car or observation car, but do not leave them unattended for long periods. Some trains allow you to bring your dog to the observation car if they stay in a carrier, so ask a crew member when you board.
What if my dog has an accident in the carrier during the trip?
Bring extra pads, wipes, and waste bags. If an accident happens, clean it up as much as you can and notify a crew member so they can help. You may be charged a cleaning fee if damage to the train is significant. Taking your dog out at station stops helps prevent accidents during longer trips.
Can I buy a ticket for my dog to sit in its own seat?
No. Dogs are not sold individual seats on any U.S. passenger train. Your dog must travel in a carrier under your seat or in your lap, or on a leash in designated areas. You pay only the pet fee, not a full ticket price.
Are there trains that do not allow dogs at all?
Yes. Amtrak's Northeast Regional, Palmetto, and Silver Service routes do not allow pets. Some commuter rail systems also have pet-free policies on certain lines. Always check the specific railroad and route before you book.
What happens if I bring my dog on a train without paying the pet fee?
You can be asked to get off the train at the next stop, and you may be charged a fine or refused service on future trips. Always pay the pet fee upfront when you book your ticket to avoid problems at the station.
