I've travelled multiple times in this train in both directions. It usually gets patronage from Siwan, Chhapra and Mau only. No one boards this train from SMI or MFP or HJP.
Unfortunately once my aunt was travelling alone in this train with my little cousin. That time it used to run avg 6hrs delayed. Her train reached Chhapra around 8pm and the whole coach got empty. Since it was February, so it was really dark outside. Being alone in coach with a lil kid horribly scared her. Thanks to the helpful attendants who locked all the doors and sat in next compartment, provided safety to her, until she reached MFP.
