if the departure is at 10am from SDAH, then it will reach very late in winter at NDLS. also regularly it will be stopped around ETW for Duronto (ALD,HWH,BBS) and around ALJN for Patna Rajdhani crossing.
with early morning it will get priority in every sector.
also in winter due to fog, the recovery time will be more if the NDLS arrival time is 03:50.
