Another one for the Russian Banya, this design from trains serving during the great patriotic war where they were used for bathing and sanitary purposes. A Russian war generally means way more death and misery than the average person is used to, but I can try to imagine how nice it would be to have this baby roll up on those narrow guage railways.
