A four-track Trans-Siberian Railway in 1895

What changes if Imperial Russia suddenly receives a uniform-gauge, four-track railway from St Petersburg through Moscow to Vladivostok in 1895?

It could transform wartime movement and overseas trade, but only if Russia can supply rolling stock, maintain an immense route, and overcome bottlenecks such as Lake Baikal.

The railway's value depends on whether the railway arrives with locomotives and wagons, and whether its gauge matches the rest of Russia. Four tracks could separate stopping trains from expresses or passenger traffic from freight, while allowing trains to continue running during maintenance on another line. The panel dates the historical completion of double-tracking to 1939 and questions whether Imperial Russia in 1895 could maintain twice that infrastructure. A usable system would improve supply during the Russo-Japanese War, although Russia would still have the same commanders. In the First World War, Vladivostok could handle imports and exports when the Baltic and Black Sea routes were constrained. These benefits depend on supporting infrastructure and maintenance capacity.
