Pets
Guide dogs accompanying visually impaired persons as well as dogs assisting disabled persons or working with police or security personnel are always welcome on board.
Dogs, cats and other pets may be transported as long as they do not cause inconvenience to other passengers. Pets travel free of charge. On the metro and commuter trains pets can be transported only in compartments with no sign indicating prohibition on the outside.
Small pets travel most comfortably on your lap, larger pets in the legroom. At stations, it is advisable to use a lift with your pet, when possible, instead of taking the stairs.
