Low maintenance cz of less TAT @ DBG is main reason along with late run which lead in no Wash Line view @ DBG...
Train runs on Saharasa Garib Rath slot, which never seems been followed alike Garib Rath, which hamper its schedule & hence late start @ DBG...
Further not just this train but many regular ones from DBG arnt well maintained (Sometimes passenger also ruin situation as Co-Passenger in SBC Raj even complained about the washroom habit of many ones in SBC Raj)!!!
