On March 14, 1972, Frankfurt Airport (FRA) entered a new era: with the opening of Terminal 1, one of the most modern terminal buildings in Europe at the time began operations. From check-in to boarding, all travel processes for passengers were combined under one roof for the first time. At the same time, the close connection between various modes of transport began: the underground regional train station connected the airport to the Deutsche Bahn network. "The opening of Terminal 1 marked the beginning of a new era at the airport," said Stefan Schulte, CEO of the airport operator Fraport, on the occasion of the anniversary. "Larger aircraft, short transfer times, an automatic baggage handling system that was unique in the world and an infrastructure that was extremely modern for the time ensured the airport's future viability as Germany's most important air traffic hub. Together with our partners, we have continuously developed the airport over the past 50 years." Planning for what was then known as the "Terminal Mitte" began in the 1950s. During the seven-year construction period, up to 2.500 people worked on the major project. The investment costs for the terminal facilities and the station were around one billion German marks. The core of the terminal was and is the baggage handling and sorting system, which has made it possible to make transfer times of 1974 minutes since it was commissioned in 45. "The planning shows enormous foresight: the opening of the regional station was the starting point for the successful intermodal connection. At the beginning, 100 trains called at the airport every day, but today there are over 500 trains at the regional and long-distance stations. We are still pioneers in terms of intermodality today; no other airport in Germany is better equipped for this."
