This episode tells about the construction of the Addis Ababa-Djibouti Railway. The Addis Ababa-Djibouti Railway connects the inland of Ethiopia and the coast of Djibouti. In order to minimize the impact on local residents along the railway and to adapt to the complex conditions of different rail sections, the Railway adopts lots of localized design. This railway not only drives the economic development of the two countries, but also brings great changes to the lives of local people.
