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 use and how large your dog is. Most major U.S. passenger railroads — Amtrak, commuter rail systems, and regional carriers — permit dogs in the cabin, but they impose size limits, require advance notice, and charge fees. Some railroads allow only service dogs in the main cabin and relegate other dogs to a separate pet car or kennel area. A few regional systems have no pet policy at all.
The most important step is to contact your specific railroad before you book. A five-minute call to their customer service line will tell you whether your dog can travel, what size limit applies, what paperwork you need, and what the fare is. Waiting until you arrive at the station with your dog creates the risk of being turned away.
Key Takeaways
- Amtrak allows dogs under 20 pounds in a carrier in the cabin and charges a flat fee per trip, but does not permit dogs in sleeping cars or the dining car.
- Most commuter rail systems (Northeast Regional Rail, MARC, Caltrain, and others) allow leashed dogs during off-peak hours only, with no fee.
- Service dogs and emotional support animals have different rules — service dogs travel free and are not subject to size limits, while emotional support animals are usually treated as pets and subject to the same fees and restrictions.
- You must contact your railroad in advance; showing up with an undeclared dog often results in denial of boarding or removal from the train.
- Some railroads require a health certificate or proof of vaccination, particularly for international travel or certain routes.
Amtrak's pet policy and what it covers
Amtrak permits dogs and cats under 20 pounds in a carrier in the coach cabin. The pet fee is a flat $25 per pet, per trip, regardless of distance. Your dog must remain in the carrier at all times except during brief stops at stations, when you can take your dog outside to use the restroom on a leash.
Amtrak does not allow pets in sleeping cars, the dining car, or the lounge car. If you are traveling overnight, your dog stays in your coach seat in its carrier. This is a significant limitation for long-distance routes where you might otherwise move around the train. Amtrak also requires that you notify them when you book your ticket — you cannot add a pet after purchase.
Service dogs are exempt from the size limit and the $25 fee. They are permitted in all areas of the train where passengers are allowed, including sleeping cars and the dining car. You will need to identify your dog as a service dog when you book; Amtrak may ask for documentation of the dog's training, though they cannot demand a specific certification.
Commuter rail rules vary by system and time of day
Most commuter rail systems in the Northeast, California, and other regions allow dogs on trains, but usually only during off-peak hours — typically after 10 a.m. on weekdays and all day on weekends. Dogs must be leashed or in a carrier. There is no fee on most systems.
The Northeast Regional Rail Alliance (which includes MARC in Maryland, NJ Transit, and others) permits leashed dogs on off-peak trains. Caltrain in California allows dogs in designated cars during off-peak hours. The Chicago Metra system allows leashed dogs on all trains at no charge. However, the rules differ from system to system, and some smaller regional railroads do not permit pets at all.
The off-peak restriction exists because commuter rail is crowded during rush hours, and railroads want to avoid conflicts between passengers and dogs. If you plan to travel during peak hours, call ahead to ask whether exceptions are made for small dogs in carriers or service dogs.
Service dogs versus emotional support animals on trains
A service dog is a dog trained to perform a specific task for a person with a disability — guiding a blind passenger, alerting a deaf passenger to sounds, or interrupting a panic attack, for example. Service dogs are not pets and are not subject to pet restrictions. They travel free on all railroads, are permitted in all passenger areas, and do not need to be in a carrier.
An emotional support animal (ESA) is a dog whose presence reduces anxiety or provides comfort but which has not been trained to perform a specific task. Railroads treat ESAs as pets, not service animals. This means your ESA is subject to the same size limits, fees, and carrier requirements as any other dog. You will need a letter from a mental health professional stating that your dog is an ESA, but this letter does not override the railroad's pet policy.
The distinction matters because many people assume an ESA has the same legal status as a service dog. It does not. If your dog is an ESA, budget for the pet fee and plan to keep your dog in a carrier during the trip.
Health certificates and vaccination requirements
Most domestic train routes do not require a health certificate or proof of vaccination. However, some railroads ask for proof that your dog is current on rabies vaccination, particularly if you are traveling across state lines or on a route that passes through multiple jurisdictions.
If you are traveling internationally — for example, on a train from the U.S. into Canada — you will need a health certificate issued by a veterinarian within 10 days of travel, proof of rabies vaccination, and sometimes proof of other vaccinations depending on the destination country. Contact the railroad and the destination country's customs authority at least two weeks before your trip to confirm what documents you need.
How to book a train ticket with your dog
Call the railroad's customer service line or visit their website and look for the pet policy page. Write down the specific rules: size limit, fee, whether your dog needs to be in a carrier, whether there are time-of-day restrictions, and what documentation you need to bring.
When you book your ticket, inform the railroad that you are traveling with a dog. On Amtrak, you must add the pet to your reservation at the time of booking — you cannot add it later. On commuter rail, you typically do not need to pre-book, but calling ahead to confirm the current policy is still wise because rules change.
Arrive at the station early on the day of travel. Bring your dog on a leash and have any required documentation (vaccination records, health certificate, service dog letter) ready to show. If your dog is in a carrier, have the carrier easily accessible so staff can inspect it if needed.
What to pack and how to prepare your dog for train travel
Bring water and a collapsible bowl so your dog can drink during the trip. Pack enough food for the journey plus extra in case of delays. Bring waste bags and plan to use station stops to let your dog relieve itself. If your dog is anxious in enclosed spaces or around noise, consider talking to your veterinarian about calming options before the trip.
If your dog will be in a carrier for several hours, make sure the carrier is large enough for your dog to stand, turn around, and lie down. A carrier that is too small causes stress and can be grounds for removal from the train. Practice short trips in the carrier before your scheduled train journey so your dog becomes accustomed to it.
On the day of travel, exercise your dog before boarding so it is calm during the trip. A tired dog is less likely to bark or become restless in a carrier.
Frequently Asked Questions
Can I take my dog in the dining car on Amtrak?
No. Amtrak does not permit pets in the dining car, lounge car, or sleeping cars. Your dog must remain in your coach seat in its carrier. You can take your dog out during station stops to use the restroom on a leash.
What if my dog is too large for Amtrak's 20-pound limit?
Amtrak does not make exceptions for dogs over 20 pounds unless the dog is a service dog. If your dog exceeds the weight limit, you cannot bring it on Amtrak. Some commuter rail systems have no size limit as long as the dog is leashed, so check your local system's rules.
Do I need a letter from a doctor to bring my emotional support dog on a train?
You will need a letter from a mental health professional stating that your dog is an ESA, but this letter does not exempt your dog from pet fees or size limits. Railroads treat ESAs as pets. A service dog letter is different and does exempt your dog from restrictions, but only if your dog is actually trained to perform a task.
Can my dog travel in a pet carrier under the seat instead of a large carrier?
It depends on the railroad. Amtrak requires a carrier large enough for the dog to stand and turn around. Some commuter rail systems allow a leashed dog instead of a carrier during off-peak hours. Check your specific railroad's rules before you buy a carrier.
What happens if my dog barks or becomes disruptive on the train?
If your dog becomes disruptive, train staff can ask you to remove the dog at the next station. To avoid this, exercise your dog before boarding and consider calming options if your dog is prone to anxiety. Keeping your dog in a carrier also reduces the likelihood of disturbance.
