Connectivity to Lucknow and Ranchi. Despite being two state capitals not being quite far from each other, they have 0 trains/connections.
A proper train from Lucknow to Raipur/Bilaspur. Whilst a tri weekly Garib Rath runs, everyone knows that it's not molded to everyone's demands. 3AE coaches aren't everyone's choice. A generic M/E train with GN,SL,3A and 2A offers more flexibility for the user.
