Chinese Eastern Railway Liaodong from China in 1898. Officially, traffic on the line started in November 1901, but regular passenger traffic from St. Petersburg to Vladivostok across the Trans-Siberian railway did not commence until July 1903. In 1898, construction of a 550-mile (880 km) spur line, most of which later formed the South Manchuria Railway, began at Harbin, leading southwards through Eastern Manchuria, along the Liaodong Peninsula, to the ice-free deep-water port at Lüshun, which Russia was fortifying and developing into a first-class strategic naval base and marine coaling station for its Far East Fleet and Merchant Marine. This town was known in
Chinese Eastern Railway the west as Port Arthur, and the Russo-Japanese War (1904–1905) was fought largely over who would possess this region and its excellent harbor, as well as whether it would remain open to traders of all nations (Open Door Policy). The Chinese Eastern Railway was essentially completed in 1902, a few years earlier than the stretch around Lake Baikal. Until the Circumbaikal portion was completed (1904–1905; double-tracked, 1914), goods carried on the Trans-Siberian Railway had to be trans-shipped by ferry almost a hundred kilometers across the lake (from Port Baikal to Mysovaya). The Chinese Eastern Railway became important in international relations.
