Russia and Iran have signed documents on the construction of the Rasht-Astra railway line, Russian Deputy Prime Minister Andrei Nikitin said. The Rasht-Astra line is the final component of a continuous rail route from Russia to Iran's southern ports. This section will connect the railway networks of the two countries and open a smooth route for the supply of goods to the Persian Gulf and the countries of the South Asian region. The implementation of the "North-South" international transport corridor will allow to unite the transport systems of Russia and Iran into one strategic network.
