Rail-freight Junctions

Abstract
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 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.
Results comprise the creation of a prototype with various functions
implemented: (i) a disposition system for an effective empty wagon handling,
(ii) an analysis tool for more efficient handling processes of the shunting yard
(e.g. with adjusted time frames for opening hours) and (iii) a tool for reducing
bottlenecks within the junction through smoothing the capacities by timely
information use. Important manufacturers located at the site or nearby are
looking for cost-efficient and operation-effective ways of getting their goods,
components and services in and out of the junction. Aspects like an optimized
availability of operational resources and a maximized degree of capacity
utilization are fundamental to offer competitive transport chains and to gain
