Before World War I: the Russian scheme[edit]
Then, a few days after the outbreak of World War I, Russia repudiated its obligation to build the Tehran-Khanaqin line under the Potsdam Agreement.
After World War I[edit]
After the substantial interruption of World War I, the project for constructing a standard-gauge 1,435xc2xa0mm (4xc2xa0ftxc2xa08+1xe2x81x842xc2xa0in) railway across Iran was initiated by Reza Shah Pahlavi as part of numerous reforms contributing to the drastic modernization of Iran that occurred over the decades between World War I and World War II.
In the following years Reza who became Shah in 1925 had legislation passed in parliament which secured internal Iranian funding for the railroad project from taxes levied on consumption of sugar and other goods thus excluding a new round of external debts that had bogged down the rulers of Iran before World War I.
