Two major issues of secondary lines rail transport are need to change the train for many destinations and to be bound to a timetable. Pods can be used to adopt rail transport better to the users demand by higher flexibility and efficiency as well as realising on-demand rail transport. The Project Pods4Rail aims to develop a concept for Pods and Pod-Carriers on Railway in order show the approach. Pod-carriers are serving as a moving infrastructure and the pods are loaded and locked on them for the transport. The main focus in Pods4Rail is the rail pod-carrier, which is presented in detail. Nevertheless, Pod-Carrier for Road and Ropeways are taken into consideration on a conceptual level to ensure the transferability of the concept. Related use cases and business cases are identified and analysed.
