International Air Rail Organisation

About the IARO.

Conceived in 1997 and formally launched in 1998, the International Air Rail Organisation helps the people planning and operating airport rail links learn from one another. Its reports, events, database and introductions turn project experience into practical guidance.

IARO publishes reports, holds meetings, maintains Airport Railways of the World and arranges introductions so that project experience is not lost between cities.

Reliable rail access can reduce road trips to airports. IARO helps members examine operating evidence and understand how outcomes vary between markets.

The current programme, sometimes called IARO 2.0, restarted in 2023 after a three-year pause.

Meetings since the 2023 restart.

  • The 2023 conference at Heathrow marked 25 years of Heathrow Express, with visits to Heathrow, Luton DART and the Elizabeth line.
  • Milan 2024 covered Malpensa’s North Rail Access.
  • Paris 2025 was hosted with Groupe ADP.
  • Brussels, 7–8 October 2026, is the next event.

What is an airport rail link?

Any rail that serves an airport

Direct services, light rail, metros, long distance and high speed — plus rail connected by a transit or bus to the terminal.

Operational and planned links

Explore passenger services and, with membership, planned schemes and cargo connections in Airport Railways of the World.

The well-known examples

Hong Kong Airport Express and Heathrow Express; Munich S-Bahn and Paris CDG RER; London City DLR; Frankfurt ICE; JFK AirTrain.

IARO exists so that people planning and operating airport rail links can learn from one another.
