Most trains allow dogs, but the rules depend on the railroad and your dog's size
Whether your dog can ride a train depends on which railroad you are using and how large your dog is. Most major U.S. railroads — including Amtrak, commuter rail systems, and regional carriers — permit dogs in passenger cars, but each has its own rules about size limits, crate requirements, and where dogs can sit. Some railroads charge a fee; others do not. A few restrict dogs to certain cars or times of day. Before you book a ticket, you need to check the specific railroad's pet policy, because what works on one line will not work on another.
The key is to contact the railroad directly or visit their website before you purchase your ticket. Pet policies change, and some routes do not permit dogs at all. Once you know the rules for your specific trip, you can decide whether train travel makes sense for your dog and what you need to bring.
Key Takeaways
- Most railroads allow dogs but require them to be in a carrier, crate, or on a leash, depending on the railroad's rules.
- Small dogs under 25 pounds often travel free or for a small fee, while larger dogs may face higher charges or restrictions.
- You must contact the railroad directly or check their website before booking, because pet policies vary widely and some routes do not permit dogs at all.
- Service dogs and emotional support animals have different rules than pet dogs, and you may need documentation to bring them aboard.
- Arriving early, keeping your dog calm, and having vaccination records on hand will make the trip smoother for you and other passengers.
How Amtrak's pet policy works
Amtrak, the national passenger rail service, allows dogs and cats in most of its routes, but only in specific seating areas. Small pets (under 20 pounds) can travel in a carrier that fits under your seat, and Amtrak charges a flat fee of $25 per pet, one way. Your pet must stay in the carrier for the entire trip — you cannot let it out to walk around the cabin.
Larger dogs do not may have access to for Amtrak's pet program on most routes. However, Amtrak's Northeast Regional and Keystone Corridor lines (connecting Boston, New York, Philadelphia, and Washington, D.C.) allow dogs of any size in a designated pet car, also for $25 per pet. In the pet car, your dog can move around more freely, but it must be leashed or under your control at all times. You will need to book your ticket in advance and mention that you are traveling with a pet, because pet spaces are limited.
Commuter rail and regional railroad rules
Commuter rail systems that serve major cities — such as the Long Island Rail Road (LIRR), Metro-North Railroad, SEPTA in Philadelphia, and Caltrain in California — each set their own pet policies. Most allow small dogs in carriers during off-peak hours (typically after 10 a.m. on weekdays and all day on weekends), but some restrict pets to certain cars or require them to be in a closed carrier at all times.
The Long Island Rail Road, for example, permits dogs in carriers on all trains but charges no fee. Metro-North allows dogs in carriers on weekends and holidays and after 10 a.m. on weekdays, also free. SEPTA allows leashed dogs on most of its regional rail lines during off-peak hours. Caltrain permits dogs in carriers or on leash in designated areas. Because these rules change and vary by line, call the railroad's customer service number or visit their website before you travel.
What counts as a service dog versus a pet
Service dogs — animals trained to perform specific tasks for people with disabilities, such as guiding someone who is blind or alerting someone to a seizure — are not considered pets under federal law and are permitted on all trains without a carrier or fee. You do not need to show special documentation, but railroad staff may ask what task the dog performs. Emotional support animals (ESAs) and therapy dogs are treated differently: they are not automatically permitted like service dogs, and different railroads have different rules about whether they can travel.
If you have an emotional support animal, check with the specific railroad before booking. Some railroads treat ESAs like pets and require a carrier; others may have separate policies. Bring any documentation you have (a letter from a mental health professional, for example), but understand that railroads are not required to accept ESAs the way airlines are. Service dogs, by contrast, will be allowed on any train.
Fees, booking, and what to bring
Pet fees range from nothing to $25 per trip, depending on the railroad. Amtrak charges $25 one way for pets under 20 pounds on most routes. Most commuter rail systems charge nothing. Some regional railroads charge a small fee or require advance notice. When you book your ticket online or by phone, tell the railroad that you are traveling with a dog so they can note it on your reservation and confirm the pet policy applies to your specific route and time.
Bring your dog's vaccination records (especially proof of rabies vaccination) in case you are asked, though most railroads do not require them. Pack water, a collapsible bowl, and any medications your dog takes. Bring waste bags and plan to clean up any accidents when ready. If your dog is anxious or prone to barking, consider a calming aid or muzzle (if your dog is trained to wear one) to keep other passengers comfortable. Arrive at the station early so you have time to get your dog settled before boarding.
Restrictions and what to avoid
Do not assume your dog can travel on every train. Some railroads, regional lines, or specific routes do not permit pets at all. High-speed rail services and some long-distance overnight trains have stricter rules or ban pets entirely. Always check before you book. If your dog is large, aggressive, or has a history of anxiety or accidents, some railroads may deny boarding or require a muzzle and leash at all times.
Dogs are not permitted to sit on seats or take up a passenger's space. They must remain in a carrier, crate, or at your feet on the floor. If your dog is disruptive — barking, lunging, or showing signs of aggression — the conductor can ask you to leave the train at the next stop. Keep your dog calm and quiet, and be prepared to move to a less crowded car if your dog is stressed by the noise and motion of the train.
Planning a longer train trip with your dog
For trips longer than a few hours, plan bathroom breaks and exercise. Most trains make stops every 30 minutes to a few hours, depending on the route. At each stop, you can take your dog off the train briefly to use the bathroom and stretch, but you must stay close to the doors and reboard quickly. Do not leave your dog unattended on the train, even for a few minutes.
For overnight trips, check whether the railroad offers sleeping cars that permit pets. Amtrak's sleeping cars have different rules than coach seating, and not all routes with sleeping cars allow dogs. If you are planning a long journey, call Amtrak or the railroad directly to discuss your options, because overnight accommodations with pets require advance planning and may have additional fees or restrictions.
Frequently Asked Questions
Do I need a ticket for my dog?
No, your dog does not need its own ticket, but you may need to pay a pet fee. Amtrak charges $25 per pet on most routes. Most commuter rail systems do not charge a fee. The fee is separate from your passenger ticket and is usually paid when you book or board.
Can my dog sit on my lap during the train ride?
It depends on the railroad. On Amtrak, small dogs must stay in a carrier under your seat. On commuter rail, dogs in carriers can sit with you, but dogs not in carriers must stay on the floor. Check your specific railroad's rules before boarding.
What if my dog has an accident on the train?
Clean it up when ready with the waste bags you brought. Notify a crew member so they can note it. Most railroads do not charge extra for accidents, but repeated incidents could result in your dog being banned from future trips. Bring extra bags and plan bathroom breaks at each stop.
Can I bring my dog on an international train?
Rules for international train travel (such as Eurostar or trains in Canada) vary by country and operator. Most require health certificates, proof of vaccinations, and microchipping. Contact the specific train service well in advance, as requirements can be strict and processing times are longer.
What should I do if my dog gets anxious on trains?
Start with short trips to help your dog adjust to the noise and motion. Bring familiar toys, treats, or a blanket with your scent. Some dogs benefit from calming supplements or medications — ask your veterinarian. If your dog is severely anxious, consider whether train travel is the best option, or explore alternative transportation.
