Red Deutsche Bahn regional train standing at Frankfurt Airport railway station in Hesse, Germany, on a service towards Offenbach. The side view shows the second-class passenger carriage at the platform beneath the station roof, with its destination display illuminated and travellers visible through the windows. Frankfurt Airport is one of Germany's most important transport interchanges, combining international aviation with long-distance and regional rail services across the Rhine-Main area. The photograph is suitable for editorial coverage of Deutsche Bahn, German regional rail, airport rail connections, public transport, commuting, passenger services, integrated transport, airport access and sustainable alternatives to car travel. It can also illustrate stories about railway capacity, timetable performance, airport connectivity, regional mobility, rail fares and the everyday experience of passengers transferring between aircraft and trains at a major European transport hub.
