Central Asian Railroad Routes
Because railroad infrastructure is expensive and difficult to build, the Soviet-era network is still largely in place today, with new connections (between Kazakhstan, Turkmenistan, and Iran, for example) coming online only in the last year. The rail network remains both a symbol of the Soviet era to outsiders and a still quite common mode of transit to large groups of citizens from former Soviet countries.
