Do you know we are having general sleeping timings in Indain Railway Trains? So, many passengers might be don't know this one, actually 9:00 p.m to 6:00 a.m is the sleeping hours as per the Indain Railways. This is going to be legacy now, railway borad modified the official timings and set as 10:00 p.m to 6:00 a.m. The main intention of this is to allow passenger to sit properly in the day time, in any case either middle or lower berth passengers are sleeping after 6:00 a.m then the middle berth or upper berth passenger won't be sit properly on lower berths. And the one more thing as side berth upper passengers also don't have right to sit in lower berth between 10 to 6 a.m. One more thing is that in some trains when ever a passenger boarded into train he/she will try to sleep on berth without bouther about the co passengers.
