Bus dont ply Inter-State is local issue which cant be linked to push extra Unreserved/Class into trains. And why bus dont ply? Just to minimize useless travel & control Covid in badly infected State!!
Daily traveler are mostly worker/labourers who got MST for ICE/MEMU/DEMU short distance travel & non daily travelers need UTS!! MYS/HRR/HAS-SBC got morning & evening MEMU/DEMU/ICE to traverse no less than 2000 passenger at a go.
BGM-UBL-HRR got ICE for MST.
