First of all, Dumka - Patna Express should get General & 2S Coaches. There was no need to make RSA with Ganga Damodar.
Secondly, 13334 & 13333 both got short terminated/originated from Bhagalpur & rescheduled from their source station. So as a result 13330 got rescheduled. The best option was to cancel empty running 13333/34 but ECR didn't hesitated to reschedule all the three trains.
please wait...Translate to HindiPehle saala, Dumka - Patna Express ko General aur 2S Coaches milne chahiye the. Ganga Damodar ke saath RSA banana ka koi jarurat nahi thi.
Dusri baat, 13334 aur 13333 dono ko Bhagalpur se short terminated/originated kiya gaya aur unki source station se rescheduled kiya gaya. Iss wajah se 13330 ka bhi rescheduled hona pada. Sabse achha option tha ki khali chalne waale 13333/34 ko cancel kar diya jata par ECR ne sab teen trains ko reschedule karne se kabhi nahi peeche hati.
