Which of these allows goods to be easily transported from western Russia to eastern Russia?

The Trans-Siberian Railway is the primary transportation route that allows goods to be easily transported from western Russia to eastern Russia. Spanning over 9,000 kilometers, it connects Moscow in the west to Vladivostok on the eastern seaboard. Being the longest railway line in the world, it plays a crucial role in the movement of freight and people across this vast nation's diverse landscapes.

The Trans-Siberian Railway is not just a single rail line but a network of railways that connects the European part of Russia with its Asian part, and further leading to the Pacific Ocean. Construction began in the late 19th century and it has been a cornerstone in the development of the areas it passes through by supporting commerce and settlement. The railway crosses several major rivers, climbs through the Ural Mountains (the boundary between Europe and Asia), and skirts the edge of Lake Baikal, the deepest freshwater lake in the world. It also branches off into other countries such as Mongolia, China, and North Korea through additional lines like the Trans-Mongolian and the Trans-Manchurian.

Over time, the Trans-Siberian has become more than just a transportation route; it has been an integral component of Russia's economic expansion, facilitating trade and the exploitation of the region's rich natural resources. Travelers from around the world also use this railway to embark on epic journeys, experiencing the vastness and variety of Russia's landscapes and cultures.
