Can Dogs Go on Trains in the UK? Rules, Costs and Tips

Train travel with dogs is perfectly possible across most of the UK rail network, and in many cases completely free. Rules vary by operator, so knowing what to expect before you board makes for a much smoother journey.

Which Train Operators Allow Dogs and What Are the Rules?

The majority of UK train operators allow dogs on their services. Most permit up to two dogs per passenger, with the dog travelling free of charge. Dogs should be kept on a lead or in a carrier at all times and should not be placed on seats. The general expectation is that dogs do not cause a nuisance to other passengers.

Operators including Avanti West Coast, LNER, and Great Western Railway allow up to two dogs per passenger free of charge on most services, with some restrictions at peak times or on certain routes. CrossCountry allows dogs but recommends advance agreement for longer journeys. Transport for Wales and ScotRail have generally dog-friendly policies across most of their networks.

There are exceptions: Heathrow Express does not permit dogs other than assistance dogs, and Eurostar does not allow pets. Always check the specific operator's pet policy before booking, as rules can change.

Practical Tips for Train Travel with Your Dog

Preparation is key for stress-free rail travel. A well-exercised dog before the journey is more likely to settle quietly during transit. Bring a water bottle and collapsible bowl, particularly for longer trips, and a compact mat or travel bed provides comfort on carriage floors.

Choose quieter carriages when possible — standard off-peak coaches are usually less crowded. Book seat reservations in advance where available to ensure you have space. Avoid placing your dog on seats even if the carriage is empty, as other passengers may object to fur or scent on seats they later occupy.

For large dogs, travelling at quieter times of day gives more floor space and reduces stress. If your dog is anxious or unfamiliar with public transport, a few short practice journeys beforehand help them acclimatise. Carry waste bags and be prepared to clean up promptly if your dog has an accident.

Assistance Dogs and Exemptions

Assistance dogs — including guide dogs, hearing dogs, and mobility assistance dogs — have a legal right to travel on all UK public transport, including services that otherwise prohibit or charge for dogs. Under the Equality Act 2010, operators cannot refuse assistance dogs or charge their handlers extra.

If your dog is a registered assistance dog, carry your identification documentation from the relevant charity (Guide Dogs UK, Hearing Dogs for Deaf People, etc.) to show on request. Even on services where dogs are permitted, assistance dogs may access additional areas such as first class if accompanying their handler.

Emotional support animals do not have the same legal status as trained assistance dogs in UK law, and operators are not required to accommodate them in the same way.

What to Do If Your Dog Is Unwell on the Train

Motion sickness can affect dogs on trains, though it is less common than car sickness since trains tend to produce less lateral movement. Signs include excessive drooling, restlessness, yawning, or vomiting. If your dog is prone to travel sickness, speak to your vet about anti-nausea medication beforehand — prescription options such as Cerenia are very effective and available from your vet after a consultation costing £40–£65.

If your dog becomes seriously unwell during a journey, ask train staff for assistance. Most UK intercity routes pass through towns with veterinary practices. Knowing the [emergency and out-of-hours vets](/emergency-out-of-hours-vets/) in towns along your route before you travel is sensible forward planning.

For minor issues, a familiar toy or blanket from home can help a dog settle. Feeding nothing or a light meal 4–6 hours before travel reduces the risk of motion sickness for most dogs.
