Train to the roof of the world

Remember the general knowledge quiz rounds one had in school?A sure fire question was "name the city which is called the roof of the world" and every hand will shoot up for "tibet".But then one more quiz question will be doing the rounds for which the right answer is "tibet" once again.It has just been connected by the "Highest elevation railways in the world".
China is proud to annouce this feat to the world recently.The railway line is across 5500 metre high mountain ranges of which 550 km is frozen!.The entire stretch is roughly 2000 km long over one of the most arduous terrains in the world.The last 1000 km was the toughest and was completed in 4 years!People of these inaccessible regions are simply delighted as they thought this project will go on and on and will never get completed in their lifetime.
While i was marvelling at this feat and waxing eloquent,I heard a most sobering comment.The whole project is to make India through the Himalayas more accessible.there are no altruistic designs.My spirits dipped.Before me the school geography lessons once again started unfolding where himalayas were picturised as the most inaccessible mountains in the world and how it has helped alter the fate of India against foreign invasions.
A pure joy tinged with remorse!
