I was stunt to listen his argument for not entering into the tunnel, since to many times on my own car, i have never stopped myself for crossing it if there any train is coming over it.
Recently signed contracts with the President of China also includes some improvement in rail network across Pakistan, which will include northern areas as well, which is not yet connected to Pakistan, with this cheap means of transport and can improve tourism allot, from there anyone can reach to Karachi till Gawadar, if this becomes reality.
Karachi also needs a mass transit to avoid rush on roads in peek hours, which seem not possible until provincial matters are not settled between elected powers.
So lets hope Pak-China's recent talks may come with some good news for this neglected means of transport with much more convenience to masses.
