Sometimes, the old station buildings have rail cars incorporated, or the rail cars are parked near the tracks with purpose-built structures.
Earlier, we noted that some German railway stations now serve other purposes. That's also true of obsolete rolling stock.

The article, which is in German, is in part an offer of rolling stock for sale, either to repurpose as a house, or for preservation. It does not appear to note that rolling stock is heavy, and that the person who aspires to live in a repurposed rail car has to pay as much attention to the subroadbed and the drainage thereof as a conscientious roadmaster does.
