The railway ministry has directed its zones to discontinue pasting reservation charts on reserved coaches of all trains at A1, A and B category stations as a pilot project for six months from March 1, an official statement said today. However, physical and digital display of charts will continue at the platforms, the ministry statement said. Based on the income from passengers, the railways classifies its stations into seven categories A1, A, B, C, D, E and F. It has 17 zones. "At those stations where electronic charts display plasma has been installed and the same is functioning properly, physical reservation charts at such platforms can be stopped," it added.
