The Moscow Metro.

Moskva.

Moscow is a great city, it is dominated by the Kremlin and its towers, it is also the capital city of a great and powerful nation, the largest on the earth. For every great city it must have great infrastructure, especially transport networks.

Stalin made sure that Moscow had a good and reliable metro system to match that of London, England and Paris France. This system that was undertaken in the 1930's has withstood the tests of time. 

But he wanted to bring the Russian Imperial court to the people and that is how he did it. Even the trains that have been built over the years have lasted well on the system, comfort, spacious and mechanically efficient.
