12140 sewagram express aur 51196 BPQ-CSTM PASS trains badnera junction par same loco aur same rake ke sath ate hai ya different loco aur different rake.
I think different rakes ke sath different time par ate hoge
see thisisme bata raha hai ke 51196 badnera par 56 min late departure hua jabke 12140 4 min before waise tt me dono ka arriving time same hai 00.20
