WHEN we board the Udhampur-bound Uttar Sampark Kranti Express at Ambala a little before midnight, my biggest fear is that I won’t be able to wake up in time to see the spanking new stretch from Jammu to Udhampur. But actually, I do. Thanks partly to the shrill chaiwala, but more due to the fascinating tableaux that begins to unfold outside my window. As the sleepy sun stretches itself, lighting up the undulating landscape in myriad hues of green, I go back to Wordsworth. ‘‘Kashmir is even more beautiful,’’ the bearded Mohammad Younis, a Srinagar-based bank manager, gently mocks at my wonderment. But having said this, he lays aside his The Da Vinci Code and proceeds to look out of the window. The Jammu-Udhampur line is the first step in a long journey to the Valley that began 22 years ago, and will link the rest of the country with the state’s interiors. It was a dream in 1982, says Maqbool Shah, a ticket-checker from Udhampur, but an attainable one. ‘‘When the violence surged, it became a mirage.’’ Twenty tunnels, 158 bridges and winding stretches not only bring Jammu and Udhampur closer by an hour, but will also make it possible for traders to transport goods headed for the Valley right up to Udhampur.
