Analyzing the Challenges behind low-rate Railway Electrification in African Countries

다국어 초록 (Multilingual Abstract)

Nowadays, constructing an electric powered railway network or electrifying the conventional one is a vigorous step in the direction of renovating the railway transportation industry, as efficiency enhancement and greatly reduced operational costs due to cutting off on the fuel expenses and high maintenance costs are among of the major paybacks that associates with electrified networks.
