There is no D1, D2, D3 in this train now. All sitting coaches are unreserved now. Booking is allowed only for one chair car coach C1. #admins pls update... 13051/52 dont have sitting reservation option.
UDL-SNT is 95% electrified and energized as well. Remaining works are Kunuri to Sainthia portion alongwith the freight loading/unloading point at Sainthia. Very soon, the road bridge could be raised higher to make way for elocos.
