well....i tell you all
the existing track between lahore and rawalpindi can have max speed of 100 km/hr....i am talking about the MAX speed...there are portion in between like Turki and Sohawa..where train can not go faster than 65 km/hr...due to steep gardient and reverse curves.......if bullet train is to run...then new track alongwith entirely new alignment will have to be laid....and thats not end of storey.....in order to have maintenance of this new track the old methods of track maintenance will have to be abolished...track machines and various other mechanical equpment will have to be purchased in order to maintain the new track.....the investment needed will be approximately 100 billion rupees..........
IF someone can arraange that sort of funds then ..it is possible to have bullet train otherwise not.......
you see..the existing infrastructure of railways is in shambles ...(((Rememeber Run Pathani Bridge))....so i think efforts should be made to improve the existing facilities...........
this is all i can tell....i have certain limitations.
