The department aims at carrying 1,100 million tonnes (mt) of freight traffic in the next five years and have laid out of 104 work proposals on the high density network routes.
The work proposals mostly concerning to capacity augmentation in the golden quadrilateral, (Delhi-Kolkata-Chennai-Mumbai), two diagonals (Delhi-Chennai and Mumbai-Howrah) and Delhi-Guwahati route.
These routes are high density network routes and carry about 75% of total traffic of railways, said a senior official.
"However, these routes are saturated at most locations now and it is essential for us to augment the line capacity to meet the target of 1,100 mt of revenue earning freight traffic in the 11th Plan.
While the dedicated freight corridor has already been announced as a major policy decision to separate freight traffic from passenger traffic on trunk routes as a long term strategy, the completion of the DFC will not be before the 12th Plan.
"So the Golden Quadrilateral, its diagonals and Delhi-Guwahati routes need to be augmented significantly to meet the target in the Eleventh Plan," said the official.
