OBHS was available in sleeper class of the train. There was a family travelling in our bay and they had a son who probably was not well. He ate/drank something and throwed up. Another passenger in our bay immediately called OBHS staff and he cleaned the floor quickly. Water was available in toilet of S5 coach. Cleanliness in the train and toilet was average. Our seats were having dust on them so we had to clean it up with papers that we carried.
