Trans-Siberian railway
Because Russia is such a big country, travel from one end and the other is an important problem. In the 1890s, the Russians began building the longest railway in the world to connect Moscow to the Pacific Ocean. Before the railway was built, the trip took about a year along very rough roads. One reason for building the "Trans-Sib" was military: to transport troops to the East in order to protect the country against Japan and China. Another reason was to transport food from the farming areas of south-western Siberia to the people in the European part of Russia. Many cities and industries are built up along the route of the Trans-Siberian Railway. In 1900, it connected with the West Siberian Railway.
