I believe railfanning is independent of class of travel. We see a lot of sights and sounds while traveling by rail. 99% of the time we travel by reserved or higher classes (as the photos posted will demonstrate) and I'm sure you would have had no problem if a photo showing the interior of a 1A class LHB coach was posted with occupants. No doubt you will agree that the characteristics of upper class travel is the great bedding, good food, tables, electric sockets, etc.
The photo I posted was of that remaining 1% of the time - when people like us (I mean visitors to the forum) travel unreserved. In II UR Class, the characteristics are different - it is...
more... crowded interiors, lower class co-passengers, dirty flooring, lighting and so on. All of these are depicted in the photo. It is adding no more or no less 'value addition' than a photo of 1A LHB Rajdhani or Duronto.
