The Yar Express of Thar
There are many railway links from British days that crisscross the present frontier between India and Pakistan, and India and Bangladesh. For decades, these have been dead-end lines on each side, and the hope has been that some day these lifelines of yesteryear would be revived to generate people-to-people contact among common folks. Air travel clearly does not contribute so much to building confidence, as evident from stagnating relationships despite the decades-long existence of air links between Karachi, Bombay, Lahore and Delhi.
A train link has three benefits: the common people get the opportunity to travel into the other country; it revives the contiguous crossborder contact, which is all-important for building inter-country empathy; and lastly, the volume of travelers will be at a quantum level higher with rail rather than with air (visa regimes permitting).
