The recent EU Commission paper on the establishment of a “Primary European Rail Freight Network” is the confirmation that Europe wants to develop a long term freight sustainable mobility.Infrastructure investments are costly and take long time to come to fruition. Hence force the need to adopt a realistic mid term strategy for developing the use of freight trains to bridge the gap up to when the new infrastructure investments will be completed delivering the much needed capacity.These goals can be achieved by removing over time the conflict on the same rail tracks between freight and passengers by developing corridors oriented to freight and extracting the best productivity from each available modality or from the combination of them. The TIGER project Rationale is driven by the European need of achieving a greater degree of effectiveness, efficiency and competitiveness on the Rail Freight Network. This is now perceived as being key for a more sustainable freight mobility. The reduction of road congestion, accidents, emission on the atmosphere and the negative effects on climate changes are leading to a safer and better environment for improving the quality of life of European citizens. In particular the recent breaks in trends in global trades brought about by EU enlargement and by the enormous traffic flows with the Far- East and South East Asia, handled by giant container vessels, have highlighted the impossibility of road modality of sustaining by its own the future European need of freight mobility. Port congestion has become a common feature both in the North and South of Europe to the extent that only a new distribution system to/from ports to inland destinations based on industrial intermodal shuttle trains represents the solution of this problem. The challenge in TIGER is therefore to provide a solution to EU ports and road congestion reaching inland European destinations in an industrial and effective way leading to sustainable mobility
