In the TAG 2011 version there is a mention of few trains-like Shalimar Patna Duranto, Sealdah Puri Duranto and ajmer nizamuddin Duranto. I really wonder how are these trains going to be strikingly useful. We already have a Howrah Puri Duranto, which shows availability in abundance most of the days. We do have janshatabdi, Garibrath for Patna, and host of other train cnnecting Howrah and Patna. And finally from Nizamuddin to Ajmer a Duranto? There is already a shtabdi. and the distance is too negiligible.
