 GM-EMD heavy-duty freight locomotive model GT26CW 


The GT26CW locomotives purchased from South Korea are similar to locomotives running in the I.R. Iran Railways. Larger fuel tank, higher axle load, more efficient suspension system, upgraded comfort facilities in the cabin are among the advantages of such locomotives in comparison with similar models available in Iran. These locomotives are utilized after undergoing various rehabilitation and modification of hooks, side buffers etc.
