Most trains allow dogs, but the rules depend on the railroad and the dog's size

Yes, you can bring a dog on most trains in the United States, but the specific rules vary by railroad company and route. Some trains allow dogs of any size in a carrier; others permit small dogs in the cabin and require large dogs in a pet car; still others have no pets policy at all. Before you book, you need to know which railroad operates your route and what that company's actual pet policy is, because the rules are not standardized across the industry.

The major U.S. passenger railroads—Amtrak, regional commuter lines, and light rail systems—each set their own pet policies. Amtrak, which operates long-distance and regional routes across the country, allows dogs on most of its trains but with restrictions on size, number, and location. Commuter railroads like the Long Island Rail Road, NJ Transit, and BART have their own separate rules. Local transit systems rarely allow pets at all except service animals. You cannot assume one railroad's policy applies to another.

Key Takeaways

  • Amtrak allows one dog per passenger on most routes, but the dog must weigh 25 pounds or less and travel in a carrier in your sleeping car or coach seat.
  • Some regional and commuter railroads prohibit pets entirely, while others allow small dogs in carriers only during off-peak hours.
  • Service animals and emotional support animals have different rules than pets and are usually exempt from size and carrier requirements.
  • You must contact the specific railroad before booking to confirm the policy for your route, because rules change by train and region.
  • Fees for traveling with a dog typically range from $10 to $25 per trip on Amtrak, though some commuter lines charge differently or not at all.

Amtrak's pet policy: size limits and carrier requirements

Amtrak allows dogs on most of its trains, but only if they weigh 25 pounds or less and travel in a carrier. The carrier must be leak-proof and fit under your seat or in the space beside you. You can bring one dog per passenger, and the dog must stay in the carrier during the entire trip except when you are in a private sleeping car, where you may let the dog out in that car only.

Amtrak charges a pet fee of $25 per dog, per direction of travel. This means if you travel from New York to Boston and back, you pay $25 each way, for a total of $50. The fee is separate from your ticket and must be paid when you book. Some Amtrak routes do not allow pets at all—notably the Northeast Regional and some long-distance trains during peak travel periods. You need to check the specific route before booking, because Amtrak's website will tell you whether pets are permitted on that particular train.

Regional and commuter railroad policies vary widely

Commuter railroads that serve major cities have inconsistent pet rules. The Long Island Rail Road allows dogs in carriers on all trains, with no size limit and no fee. NJ Transit allows dogs in carriers on buses and trains, also with no fee. BART (Bay Area Rapid Transit) prohibits pets except service animals. Metra, which serves Chicago, allows small dogs in carriers on weekdays after 10 a.m. and all day on weekends, with no fee.

Because these rules differ so much, you cannot assume your local commuter railroad follows the same policy as Amtrak or as another railroad in a different region. Before you travel, visit the railroad's official website or call their customer service line to confirm the pet policy for your specific route and the day you plan to travel. Some railroads have time-of-day restrictions (no pets during rush hour, for example), and those restrictions change seasonally.

Service animals and emotional support animals have different rules

Service animals—dogs trained to perform a specific task for a person with a disability—are treated differently from pets on all railroads. Amtrak and most commuter railroads allow service animals to travel with their handler at no charge and without a carrier requirement. The dog can sit beside you or at your feet, and the railroad cannot charge a pet fee.

Emotional support animals (ESAs) occupy a middle ground. They are not trained to perform a specific task, but they provide comfort through their presence. Amtrak does not recognize ESAs as distinct from pets and requires them to follow the same carrier and fee rules as any other dog. Some commuter railroads have different policies for ESAs, but you will need to contact them directly to find out. If you have an ESA, bring documentation from a licensed mental health professional, though the railroad may not accept it as proof of the animal's status.

What to do before you book your ticket

The first step is to identify which railroad operates your route. If you are traveling between major cities, it is likely Amtrak. If you are commuting within a metropolitan area, it is a regional or commuter line. Once you know the railroad, go to their official website and search for "pet policy" or "animals on trains." Most railroads have a dedicated page that lists size limits, carrier requirements, fees, and any time-of-day restrictions.

If the website does not answer your question, call the railroad's customer service line. Have your travel dates and route ready, because some policies change by season or by specific train. Ask whether the pet policy applies to your exact route and whether you need to notify the railroad when you book. Some railroads require you to mention the dog when purchasing your ticket; others do not. Getting this detail right before you buy your ticket saves you from discovering a problem at the station.

Preparing your dog for train travel

Train travel is different from car travel, and your dog may find it stressful. The motion, noise, and vibration can upset dogs that are not used to it. If your dog has never traveled by train, take a short trip first to see how the dog reacts. A single-stop commuter rail trip is a good test.

Bring water and a collapsible bowl, because your dog will need to drink during the trip. Pack any medications your dog takes regularly. If your dog is anxious, talk to your veterinarian about whether a calming supplement or medication might help. Do not give your dog a large meal right before boarding, because motion sickness is common. Bring waste bags and plan to use the restroom facilities on the train or at stations to let your dog relieve itself. Some trains have designated pet relief areas at certain stops; ask the conductor when you board.

What happens if the railroad does not allow your dog

If the railroad you need to use does not permit pets, you have a few options. Some people arrange for a pet sitter or friend to care for the dog at home while they travel. Others use a pet transportation service that specializes in moving animals between cities, though this is more expensive than train travel. A few railroads allow dogs in checked baggage in a crate, though this is rare and stressful for the animal—Amtrak does not offer this option.

If you have a service animal, the railroad must allow it regardless of its pet policy, because service animals are covered under the Americans with Disabilities Act. If you believe your service animal has been denied boarding, contact the railroad's customer service office and file a complaint. Keep documentation of the denial, including the date, time, and the name of the staff member who refused boarding.

Frequently Asked Questions

Can I take my large dog on Amtrak if I buy it its own seat?

No. Amtrak's 25-pound weight limit applies regardless of whether you purchase an extra seat. The rule is based on the carrier requirement, not on the dog's ability to fit in a seat. If your dog exceeds 25 pounds, Amtrak does not permit it on most routes, even in a sleeping car.

Do I have to tell the railroad about my dog when I book, or can I just bring it to the station?

Most railroads do not require advance notice, but some do. Check the specific railroad's website or call before you book. Arriving at the station with a dog when the railroad does not allow pets will result in you being denied boarding, so it is worth confirming in advance.

What if my dog has an accident in the carrier during the trip?

Bring extra pads or absorbent material to line the carrier, and pack cleaning supplies. If an accident happens, notify the conductor. The railroad may charge a cleaning fee, though policies vary. Some railroads are understanding about accidents; others are strict. Ask about the railroad's policy before you travel.

Are there any trains that allow dogs without a carrier?

Most U.S. passenger trains require dogs to be in a carrier, with the exception of service animals. Some regional railroads may have different rules, so contact your specific railroad to ask. In general, assume a carrier is required unless the railroad explicitly states otherwise.

Can I bring my dog on an international train from the U.S.?

If you are traveling to Canada by train, VIA Rail allows dogs in carriers on most routes with a fee. If you are traveling to Mexico, Ferromex has its own pet policy. Rules for international travel are different from domestic U.S. rules, so contact the foreign railroad directly and check your destination country's import requirements for animals.
