I manya travelling in dbrt rajdhani ex want to lodge a complaint regarding the dirty bedsheets served to us. As i along with my three other family members started on the train from guwahatii around 6:00am new bedsheets were given to us but one of them was in its worst condition i would like to request the indian railways to take care of the proper hygiene of the passengers as this uncleanliness invites many diseases.
