As some readers here say, platzkart cars are likely to disappear in in the near future (at least, there are talks about it), and I would strongly oppose it. People need choice, and for some people and for some situations that would be an optimal choice. For example, if I make my way to a place where I will have a bicyclic hike and intend to sleep in a tent for a week or so, the comfort in the train is the last thing I would think of. I'd better save some money. And the same is applicable to any ride which lasts for just one night (in the late evening you board, in the morning you arrive) - all I personally need is a bench to sleep for these 6-8 hours, nothing more. So, I travel mostly in such platzkart cars (when it is not so long to go) and would be upset if they disappear.
