Try to avoid this train during season time towards Shalimar.Its a horrible train to travel during festive time in W.Bengal as the sleeper coach will be flooded with RAC ticket holders occupying seats of reserved passengers.Traveled to Bhubaneswar during Saraswati puja time in Bengal.Almost all Sleeper coaches in the entire train was packed with RAC ticket holders and their heavy luggage.In addition to sharing reserved seats & berths there were passengers sleeping and sitting in the floor blocking the doors and toilet.The recycled air in the coaches of the crowded train was suffocating.Never ever travel with family in the sleeper class of this train due security and comfort reasons.
