Best train for odisha to travelling to/from kolkata. Just a problem is regarding catering in 2S. Its not good but in CC,its great. 2S are always crowded. So while booking in advance,then mark option for window seat. Your journey will be memorable with so high speed aggression throughout the journey and no disturbance. Even the coromandel and dhauli are nothing infront of this ECoR hunk in its territory from HWH to BBS. Punctuality is the best of the standards. Most trustworthy train. At CTC,may be 10-15min late but always reaches on time or before time at BBS.
