Chennai EMU - என்னோட உயிர் டா நீ

My family is planning to take Palace Queen Humsafar and will Arrive at COR at 02:50 AM in the last week of December. Can we get 2 retiring rooms at COR, so that we can immediately tranfer from Train to Retiring Room [Since it is winter month and 1 old age pax, we dont want to take risk in such cold]. Moreover how much cold can we expect at that time ? Also, How will be retiring rooms in the winter? Will there be sufficient Blankets ? Only this train is left to heavy WL in other trains..
