Studies related to:

• construction/upgrading of cross-border and missing links;
• capacity and performance upgrade of existing lines, including removal of level-crossings and upgrades necessary for 740 meters long trains and upgrades necessary to facilitate international rail passenger and freight transport;
• capacity increase in nodes, including as regards a better articulation of long-distance and local traffic;
• interconnections between rail and other modes of transport, in particular inland waterway and maritime transport and actions aimed at the integration of the rail and air networks to make the feeder network for long-haul flights more sustainable. Actions located exclusively within the perimeter of inland ports and maritime ports shall be submitted under those priorities respectively;
• connections of freight terminals to the TEN-T Network;
• electrification of line tracks and upgrade of electrification systems.

Support will not be given to railway stations, except for railway infrastructure components. If the Action includes such components, they shall be presented as a separate work package.  Actions shall also be compatible with the alignment of operating procedures across borders in order to ensure the most effective use of the supported infrastructure.

Actions addressing the Core Network may include related elements on the Comprehensive Network, when necessary to optimize the investment. These elements may form up to 10% of the total eligible costs of the Action and shall be presented as a separate work package.
