I have heard so many people complain about how Indian Railways lack cleanliness and hygiene. People were dissatisfied with the looks and the comfort level of the compartments. So, Indian Railways unveiled refurbished coaches with aesthetically appealing and improved interior furnishings on Tuesday. The coaches are enhanced with passenger amenities and coupled with adequate fire safety measures. This video uploaded by IndianExpressOnline will give you a complete tour of a train, covering all classes (AC and Non AC).
