After travelling in Humsafars I will just say that the Water Closets (Washroom/Rest rooms) are better than normal 3A. As Coffee Vending Machines are not present in most of them. Side Curtains are removed in many. LED Display Board are of no use because they just display only one message in most HS i.e Welcome to Humsafar Express. Infact in few HS you will find normal Red LHBs as well. So for the extra features in Washrooms I am giving 3.
