There is a single railroad following the Silk Road route, which linked Xian, China with the Roman Empire by way of Central Asia.
Due to conflicting agendas, an international train route was never established. This documentary follows Ken Ogata on a journey to bring the Silk Road to life; starting in Turfan in the Xinjiang Uygur Autonomous Region, he changes trains in the westernmost part of China, and proceeds on through Kazakhstan, Kyrgzstan, Turkmenistan, Iran, and finally Turkey.
