When there is a change in CC from 16C to 8C then they need to change in reservation system. But most of them require upgrade They have turnout 4 20C rakes why don't they test trails fully for 2 weeks in september and put them from OCT 1st replacing 16C and move those to 16C to 8C replacement in next one week. Introduce the present with available 8C rakes. As it's there is no rush of requirements in occupancy or demand for Tatanagar Berhampur, Durg Vskp. Even Pune Hubli can be introduced in later stage when Mumbai Kolhapur is being planned. There are no new introduction of VB from past 6 months but rakes have rolled out, should have finalised the routes by Aug move them by Sep 1st and trails conducted. Every decision is done in last minute lobbying and no concrete approach.
