Most U.S. train services allow dogs, but the rules depend on which railroad you use and how big your dog is
You can bring a dog on Amtrak trains and most commuter rail services, but each carrier sets its own size limits, fees, and rules about where your dog sits. Amtrak permits dogs under 20 pounds in a carrier in your sleeping car or coach seat, charges a flat fee per trip, and does not allow them in the dining or observation cars. Regional commuter systems like NJ Transit, BART, and the Long Island Rail Road have different thresholds — some allow dogs of any size if they are on a leash, others cap weight at 25 pounds. A few systems, including some Northeast Regional Rail Authority lines, ban dogs entirely except service animals. Before you book, contact the specific railroad's customer service to confirm their current dog policy, because rules change and vary by route.
Key Takeaways
- Amtrak allows dogs under 20 pounds in a carrier and charges a one-time fee per trip, but the fee and exact rules vary by route.
- Commuter rail systems have their own rules — some allow any size dog on a leash, others set weight limits, and a few ban dogs entirely.
- Service dogs and emotional support animals are treated differently from pets and usually travel free with fewer restrictions.
- You must contact your specific railroad before traveling, because policies differ by carrier and sometimes by individual route.
- Bringing a dog in a carrier or on a short leash prevents conflicts with other passengers and keeps your dog safe during stops and starts.
Amtrak's dog policy and fees
Amtrak allows one dog per passenger in a carrier in coach or sleeping cars. The dog must weigh 20 pounds or less. You pay a one-time fee per trip — this fee is not per night or per segment, but per journey from your starting point to your destination. The exact amount varies by route; some routes charge around $25 to $30, while longer routes may charge more. Check the Amtrak website or call 1-800-USA-RAIL to confirm the fee for your specific route before you book.
Your dog cannot leave the carrier except in your private sleeping car. In coach, the carrier must stay under your seat or on your lap. Dogs are not permitted in the dining car, observation car, or any shared public space on the train. If you have a sleeping car, you can let your dog out in your private room, but you are responsible for any damage or accidents. You will need to take your dog outside during station stops — Amtrak does not provide designated relief areas, so plan for stops long enough to walk your dog safely away from the platform.
Commuter rail and regional railroad rules
Commuter systems that serve major cities have varying policies. BART (Bay Area Rapid Transit) allows dogs of any size on a leash or in a carrier at no charge. NJ Transit permits dogs under 25 pounds on a leash during off-peak hours only — typically after 10 a.m. on weekdays and all day on weekends. The Long Island Rail Road allows dogs under 25 pounds in a carrier on all trains. Metro-North Railroad (serving New York and Connecticut) allows dogs in carriers only, with no weight limit, and charges no fee.
Some regional systems have stricter rules. The Northeast Regional Rail Authority bans pets entirely except for service animals. Before you travel, call the railroad's customer service line or check their website for their specific dog policy. Rules can change, and some systems update their policies seasonally or in response to crowding. If you are unsure, a five-minute phone call will save you from being turned away at the station.
Service dogs and emotional support animals
Service dogs — animals trained to perform a specific task for a person with a disability — travel free on all U.S. railroads and are not subject to the same restrictions as pets. They do not need to be in a carrier and can accompany you anywhere on the train, including the dining car. Amtrak and commuter systems recognize service dogs under the Americans with Disabilities Act (ADA).
Emotional support animals (ESAs) are treated differently. Amtrak does not recognize ESAs as service animals and applies the same pet rules — size limits, carriers, and fees. Some commuter systems may have different policies, so contact them directly if you have an ESA. You may be asked to provide documentation of your disability and the animal's role, so have that information ready.
What to pack and how to prepare your dog
Bring a collapsible water bowl, bottled water, and any medications your dog takes regularly. Pack waste bags and plan to clean up when ready if your dog has an accident. If your dog will be in a carrier for several hours, choose one that allows your dog to stand, turn around, and lie down comfortably. A carrier that is too small will stress your dog and make the trip unpleasant for everyone nearby.
Take your dog for a walk and a bathroom break before boarding. On long trips, plan to get off at major stops to let your dog stretch and relieve itself. Bring a leash rated for your dog's weight and a collar or harness that fits securely — train stations are busy and chaotic, and a loose dog can bolt into traffic or get lost. If your dog is anxious in new environments, consider a calming treat or medication prescribed by your veterinarian, but do not sedate your dog without veterinary guidance.
Booking your ticket and what to tell the railroad
When you book an Amtrak ticket online, you will see a checkbox to add a pet. Select it and pay the fee at checkout. If you book by phone, tell the agent you are traveling with a dog so they can add the fee and note it on your reservation. For commuter rail, you typically do not need to reserve in advance — just show up with your dog on a leash or in a carrier and pay any applicable fee at the ticket window or on the train.
If you are traveling during a busy season or on a popular route, call ahead to confirm that the train has space for your dog. Some trains have limited capacity, and on rare occasions a conductor may ask you to take a later train if the car is too crowded. Having your reservation confirmed in advance prevents this problem.
What happens if your dog causes a problem
If your dog barks excessively, bites, or damages property, the conductor can ask you to leave the train at the next stop. You will not receive a refund, and you may be banned from future travel with that dog. Keep your dog calm and contained at all times. If your dog is reactive to strangers or other dogs, a carrier is the safest option for everyone.
Accidents happen — if your dog has an accident in the train car, clean it up when ready with supplies you brought, and notify a crew member so they can note it. Most railroads are understanding about one-time accidents, but repeated incidents can result in removal from the train.
Frequently Asked Questions
Can I take a large dog on Amtrak if I buy a sleeping car?
No. Amtrak's 20-pound weight limit applies to all dogs, including those in sleeping cars. The sleeping car allows your dog out of the carrier in your private room, but the weight restriction remains. If your dog exceeds 20 pounds, Amtrak does not permit it on any train.
Do I have to pay a fee for my dog on commuter rail?
It depends on the system. BART charges no fee. NJ Transit charges no separate fee but restricts dogs to off-peak hours. Metro-North charges no fee. Check your specific railroad's website or call their customer service to confirm whether a fee applies to your route.
What if my dog gets sick or injured during the trip?
Notify a crew member when ready. Amtrak and commuter rail staff can radio ahead to the next station so emergency services can meet you if needed. Keep your veterinarian's phone number and the location of animal hospitals along your route in your phone before you travel.
Can my dog sit on my lap instead of in a carrier on Amtrak?
In coach, your dog must stay in a carrier under your seat or on your lap — the carrier itself can be on your lap. In a sleeping car, your dog can be out of the carrier in your private room only. Dogs cannot roam freely in any shared train space.
What if the railroad I want to use does not allow dogs?
Some regional systems do not permit pets. If the railroad you need does not allow dogs, you will need to arrange other transportation for your dog or travel without it. Service dogs are the exception and are permitted on all railroads regardless of pet policy.
