List of IATA-indexed railway stations, bus stations and ferry terminals
Many major railway stations, bus stations and ferry terminals that are involved in intermodal passenger transport are assigned codes by the International Air Transport Association (IATA), similar to IATA airport codes. Such railway stations, bus stations and ferry terminals are typically used in air-rail alliances or code sharing agreements (commonly known as "Rail Fly") between airlines, rail lines, and ferry lines, but can also be used for buses run directly from airlines (such as the Helsinki Airport - Turku / Tampere buses directly operated by Finnair), particularly in Europe.
