The EU is aiming to double high-speed rail traffic by 2030 and triple it by 2050. But harmonising rail networks across the continent is easier said than done. While some cross-border routes have opened in 2025, other projects have been hampered by a lack of infrastructure or investment, as well as vested interests in the EU member states.

Our panelists discuss what it would take to change this situation – rail travel being a component of the EU's stated goal of becoming climate-neutral by 2050.
