Gondwana has only one AC#3 And One AC2 coach... so you most of the times end up in WL. If you plan to travel upto bilaspur / raigarh. Just get a sleeper ticket . travel upto nagpur/ katol in sleeper .... then go to ac compartment and ask TT for conversion to 3AC or 2AC. TT makes the ticket with fare difference. so that u can travel the hotter leg of journey in AC. better do this before nagpur because a lot of people try boarding at nagpur with this method and u might end up empty handed...............Avoid travel by this train as much as possible it has no pantry And Even AC3 coaches has rush and lot of people sitting inside
