Need Assistance? Rail Monsters Help Center

Yes — in many countries, small pets are allowed onboard, and some even allow larger dogs under certain conditions. However, rules vary by country and rail supplier, including:

• Whether the pet is in a carrier or on a leash

• If a pet ticket is required

• Whether muzzles are mandatory for dogs

• Allowed hours or restricted train types

When booking on Rail Monsters, you’ll see pet options if the supplier allows it. If pets are not allowed on a specific train, we’ll warn you at checkout or block the option.

To avoid issues during boarding or inspection, you should:

• Keep your pet in a carrier or on a leash (depending on size)

• Bring a muzzle if traveling with a large dog — some countries require it

• Carry any vaccination or ID documents required for cross-border trains

• Make sure your pet won’t disturb other passengers — some trains have quiet zones where pets may be restricted

Each country’s rules are different, so check the destination-specific guide before departure.
