The rail chaos that Catalonia has been experiencing for the past week is worsening. The closure of the Rubí tunnel has disrupted freight traffic leaving the Port of Barcelona bound for France. After detecting a crack in the tunnel's return section, the port has had to completely halt traffic since Monday. The disruption in Rubí, which has persisted for days, prevents trains from Barcelona and southern Catalonia from reaching the rest of the continent, as well as preventing trains from arriving from France.
