If some user can send a scanned photo of a normal berth and side middle berth in different trains,with measurements,in 2tier,3tier etc. in first and second classes,this will answer many such queries on the subject. This will also benefit many tourists who would like to know what Garib Rath, Rajdhani, Duronto and other trains look like from the interior. I do not know whether rly. website or any newspaper has published this,as they do in the case of airlines which publish photos of seat sizes in various classes in ads.
