Charging of cellphones / laptops between 10 p.m. and 7 a.m. is prohibited on this train. The charging points are disabled from 10 p.m. to 7 a.m., if you request the coach attendant, he may enable the points from 6 a.m. (as a big favour)!! Please charge your cell phones / laptops accordingly. Is it a rule, that devices cannot be charged in higher classes of travel at night? I faced this peculiar scenario in 2AC, and the TTE was quite rude when I questioned him about the same.
