the railroad is completely flat (en.rian.ru, 2011). It was built to integrate the nation into a modern rail network and is a part of the Alp Transit Railway Project which can afford the citizens the ease to travel in a better and faster manner. The tunnel site was filled with hard rocks posing a significant challenge to the excavation staff and causing immense disturbance in the surrounding area (Leung, Zhou, 2006: 153). It is known to be one of the greatest feats of engineering considering the fact that it was built at 4000 feet above sea level, on an uneven route comprising of steep gradients and sharp curves and exposed to dangerous environment which included snow and avalanches. Furthermore it was built under a mountain range which is nearly 8000 to 11000 feet high (Williams, 1968: 176). It took almost fifteen years to construct this spectacular engineering feat, costing billions of dollars. The construction of this tunnel is not only a significant engineering achievement but is also laudable for its major contribution in easing traffic and connecting various areas by enabling road transport at cheaper and faster rate. ...
