High Quality Content by WIKIPEDIA articles! This is a List of IATA-indexed railway stations, which are assigned codes by the IATA, similar to IATA airport codes. Such railway stations are typically used in air-rail alliances or code sharing agreements (commonly known as "Rail Fly") between airlines and rail lines, particularly in Europe. By assigning railway stations an IATA code, passengers on trips involving those stations can be ticketed and checked straight through to their final destination, without the bother of having to claim their baggage and check-in again when changing between the rail and air portions of a trip.
