Further potential exists to increase the capacity by modernisation of the existing system, e.g. better maintenance of tracks and signalling or use lighter materials in wagon design (Gol, 2010). Between 2006/07 and 2011/12, the 11th Five-Year Plan expects freight transport to increase from 726 Mt to 1100 Mt, and from 469 to 702 billion tkm (Raghuram and Gangwar, 2008). This represents an annual increase of 8.4%. Sea transport may ease the inland transport problem, but that would require expansion of harbour charging and discharging capacity.
