Railways being the more energy efficient mode of transport are ideally suited for the movement of bulk commodities and for long distance travel. As compared to road transport, the railways has a number of intrinsic advantages. Railways are five to six times more energy efficient, four times more efficient in land use and significantly superior from the standpoints or environment impact and safety.
Railways being the prime infrastructural sector of the country needs to expand and develop to keep pace with the growth of Indian economy. The massive investment needed for the development of the railway system has not been fully available
