The Qinghai–Tibet railway, also known as the Qingzang railway, is a remarkable feat of engineering, stretching over 1,956 kilometers from Xining, the capital of Qinghai Province, to Lhasa, the capital of Tibet. This railway holds the title of the world's highest railway, with sections running more than 4,000 meters above sea level and the highest point reaching an altitude of 5,072 meters. It not only connects the remote Tibetan Plateau to the rest of China but also offers passengers breathtaking views of unique landscapes, such as the Qinghai Lake and the Tanggula Mountains.
