European Rail Infrastructure and Cross-Border Connectivity (jonworth.eu)

• Mapping of extended trans-European rail corridors
• Technical bottlenecks affecting cross-border transit efficiency
• Impact of rail connectivity on regional economic integration

"Analyzing the EU's longest rail routes highlights critical gaps and successes in trans-European network (TEN-T) integration. Strengthening cross-border rail capacity is essential for regional resilience, energy efficiency, and reducing logistical reliance on fossil-fuel heavy air transport. These long-distance links serve as a barometer for the operational maturity of the European Single Market’s physical layer."
