I am going to take New Jalpaiguri-Howrah Shatabdi at morning 5:30, hence wish to spend the previous night in New Jalpaiguri station. Can i enter the first class waiting room at New Jalpaiguri on the previous night at around 10PM? If not, please tell how to get the dormitory or retiring room. Also tell till what time at night the autos from Tenzing Norgay bus stand to NJP are available.
