Emperor Haile Sellassie to assume management of the railway from the British and organize, rebuild the infrastructure, and integrate the railway into the national transportation grid. Under the four-year leadership of Yacob Zanios, the railway became operational and a very successful enterprise. The 1950s and 1960s were successful years for the railway, but in the 1970s the railway fell more and more out of use as the mismanagement of the railway and political unrest intensified, and in 1975 the railway was destroyed by the ruling Derg regime in Ethiopia. Much of the infrastructure was destroyed during the following years of war, and both sides used materials salvaged from the railway for fortification and other purposes. Rebuilding Eritrea won its independence from Ethiopia in 1993, and in 1994 the Eritrean president declared that rebuilding the railway was a priority for the new nation. During the war years a spirit of self-reliance had been built up, and the Eritreans refused foreign loans and expensive rework. Instead, the Eritreans decided, they would rebuild what they had left with their own efforts. Rebuilding the line started, some work going into rebuilding the workshops and station in Asmara while others set to reconstructing the Massawa end. Renovation of the main line began from Massawa westbound, recovering rails and steel ties. At the same time, restoration began on the remaining locomotives and rolling stock remaining after the conflict. Eleven steam locomotives survived, and at least six have been rebuilt to working order. In addition, several 1930s vintage Fiat 'Littorina' railcars survive and have been made operational, as well as two 1957 Krupp-built Bo-Bo diesels (the line's newest locomotives) and one of three surviving Drewry shunters, brought to the railway by the British during the war years. Finally, several road trucks have been converted to run on rail wheels. Much freight stock and a number of passenger cars also survive. The line has been restored from Massawa to Asmara, but no scheduled services traverse the whole length of the line. Charter trains for tourists now do, and regular train services exist in certain areas. While the surviving equipment is sufficient for such a limited service, the purchase or building of more is necessary to provide a serious form of transportation over the length of the line. In 2007, The Eritrean Railroad Authority requested funding to continue the Italian-era plan to extend the route to Tesseney and provide
