Last night took this train from HWH to BLS and boarded the rear side General compartment. And this is a 2010 made coach which had charging sockets near every seat and aisle. Brilliant thing for general travellers.
but sadly except that, rest all were old coaches. In SL, some coaches were new and some were dating way back to 2003-04. New ones had charging socket near every seeat but old ones had one socket near the door.
