The concept of Duranto Exp is to provide non-stop point to point service. If this train is running half empty it should be discontinued rather than have a Duranto Exp with stoppages which is quite absurd. Then there will be demands for intermediate stoppages for all Durantos. If need be it can be replaced with a super fast express with limited stoppages between Nizamuddin and Chennai.. Another reason for this train not becomimg popular as someone else has pointed out is that you waste almost 2 days in travelling unlike 1 day as in the case of Tamilnadu /GT Expresses.
