Also things like LHB conversion, DFCs, doubling, tripling, quadrapling, new line projects which are implemented now should have been done long back but instead they focussed only on introducing new and new trains adding new category of trains without anyone giving a serious thought on capacity expansion. Also Railways should have gradually raised fares in SL and GS classes too in accordance with the inflation over the years. But they didn't do any unfortunately and we are in the mess now.
