Most of the passengers amenities provided in LHB coaches are made of plastic and I doubt whether they will last long or replaced the broken ones in POH every 18 months. Coming to wash basin they are small that water will fell down while washing face and in some coaches they are fitted inside washroom wall that can be used only for hand wash. Washroom space is congested then ICF and the design of the floor is flat that water comes put to the common areas. ICF old washrooms are far better. Coming to windows of SL and GS the design of glasses has changed to sliding like in buses but they have fixed metal in between two windows that outside view is blocked and also the air flow. Atleast they should have used trasparent overlapping glass in middle with outside grill rebars.
