Trans-Asian Railway
The North-South Corridor will link Northern Europe to the Persian Gulf. The main route starts in Helsinki, Finland, and continues through Russia to the Caspian Sea, where it splits into three routes: a western route through Azerbaijan, Armenia, and western Iran; a central route across the Caspian Sea to Iran by ferry; and an eastern route through Kazakhstan, Uzbekistan and Turkmenia to eastern Iran. The routes meet in the Iranian capital of Tehran and continue to the Iranian port of Bandar Abbas.
