Certainly, without the development of transportation between Iran and Russia, we cannot talk about the development of economic exchanges between the two countries. This development must take place both on the land border and in the Caspian Sea, and an effective connection must be established between the transport companies of the two countries. Therefore, if Russia can be a window into Iran's entry into the Eurasian market and the CIS countries, it can play a serious role in increasing trade between the two countries. Currently most of Iran's problems are related to land and rail transport, and the country's rail transport is not developed in accordance with the needs of the country. On the other hand, road vehicles such as trucks have worn out and ports and wharves have not grown significantly. Currently, the Sarakhs-Tajan and Gorgan-Incheh-Burun railways are capable of sending goods to Russia via Turkmenistan and Kazakhstan. The construction of the Rasht-Astara (Iran) -Astara (Azerbaijan) railway is the most important railway transportation project between Iran and Russia, which can significantly increase the relations between the two countries and completes the north-south corridor.
