I think is train ko bhi RJPB-BANKA express ki tarah chalaya jana chahiye rajya rani exp banakar.. Raat me RNC se departure dekar subhah DUMKA se wapas RANCHI... Overnight train rahegi to jayda fayda hoga..
As patliputra exp raat me chalkar subhah 7am pe JSME aati hai.. Iska departure sham me rahe jis se ye wee hours me JSME cross karke 5am tak DUMKA aa jaye :)
