The Trans-Iranian Railway (Persian: راه‌آهن سراسری ایران) was a major railway building project started in Pahlavi Iran in 1927 and completed in 1938, under the direction of the then-Iranian monarch Reza Shah. It was entirely built with indigenous capital, and links the capital Tehran with Bandar Shahpur (now: Bandar-e Emam Khomeyni) on the Persian Gulf in the south and Bandar Shah (now: Bandar Torkaman) on the Caspian Sea in the north, via Ahvaz and Ghom. In 1961, under Reza Shah's son Mohammad Reza Pahlavi, it was extended from Bandar Shah to a new terminus in Gorgan.^[2] During the land reforms of Mohammad Reza Pahlavi in 1963, as part of the "White Revolution", the Trans-Iranian railway was extended to link Tehran to Mashhad, Tabriz and Isfahan.^[3]
