Very bad departure timing at 5.40 am, only suitable for people staying in Kolkata and very nearby, who can avail ola, uber or has a personal vehicle. For others not at all possible to reach HWH @ 5.40 am to catch train specially in winters very difficult. This train will loose passengers for sure.
Same for TATA departure, many passengers from KGP and nearby used to catch Barbil JS to reach TATA to catch PUNE and MUMBAI Duronto from TATA, now that option is also gone. Theis Duronto will surely loose a huge number of passengers over SER.
