The first lines pass though formidable mountains, and international construction firms were heavily involved in the construction. Gradients up to 1 in 36 were required, plus Hillclimbing techniques such as Spirals were required. GEOLOGICAL CHALLENGES All sorts of geological problems were encountered, which required abandonment of some tunnels, and realignment of the route through different terrain:
The principle lines were completed ahead of schedule and under budget, with the first train arriving in Tehran in about 1940. WORLD WAR II During World War II , the railway was a vital component of the Persian Corridor supply routes connecting the Persian Gulf to Central Asia and the Soviet Union . The line was of such importance that the Allies imported rolling stock of its own design, including Diesel Locomotives such as the ALCO RSD-1 . TV An exploration trip to find a cave dwelling fish named after a man called Smith, was filmed (by the BBC ?) travelling along this railway line, and some of the tunnels and deviations were visible.
