I think running Duronto with too less halts is a flop concept. One halt at least per 100-150 km is utmost required. Even rajdhanis do have halts more than Duronto! And the ones suffering heavy losses should be stopped, or at least timings should be changed to suit the people. Most important, remove flexi fare. Instead, IR can increase fare just 100-200 but no flexi fare should be entertained.
