My intention is why to create confusion among passengers with respect to category of trains. Few years back there were only express, mail, superfast and premiums like Raj md Shatabdi. Now so many categories. Rakes used for each category is defferent usually(wrt interiors or LHB technology). Just like now no new Garib raths. currently running Garib raths will have to be scrapped after few years or to be converted to Humsafar
