Rail Europe does allow pets on board trains, but the policies may vary depending on the specific train operator and the country you are traveling in. Generally, small pets such as dogs and cats can be transported in a carrier or bag that fits under the seat. The carrier must meet certain size requirements, often not exceeding 30 centimeters in height, and the animal may need to be vaccinated or have a pet passport, depending on the destination. Larger dogs may not be allowed in passenger areas and might require a special ticket or be transported in a designated area.
It is essential to check the specific policies of the train company you will be using, as each has its own rules when it comes to pet travel. Additionally, certain trains may have restrictions during peak travel times or may not allow pets at all. For the most accurate and up-to-date information regarding bringing pets on board Rail Europe trains, travelers should consult the relevant section of the website or the booking terms provided at the time of ticket purchase.
