Rail freight junctions have the primary role of efficiently moving freight for the domiciled forwarders through interconnections to national and international transport corridors. To fulfil transport demands a holistic view of all relevant infrastructural components (e.g. intermodal facilities, shunting yards) is needed. Intermodal freight hubs use two or more forms of transportation to move goods. Freight yard complexes with their main functional components involving (i) receiving, (ii) switching and (iii) departure yard are directed to ensure transport in individual wagons. That results in a distress, when block trains, intermodal trains and full-load traffic concur within large junctions. Characteristically, large freight junctions are often historically grown, therefore limited in capacity and operationally inefficient. Based on that, the purpose of the project OPTImodal (project is currently work in progress) implies to bring different players of one considered junction together, in order to optimize logistics and transport processes and to develop the (cooperative) use of the infrastructural and operating resources on site.
