nice find
Second picture has german label "Entwurf" = concept

Could be this are advance design of the „Flugbahn-Wagen“ by Franz Kruckenberg ?
Better know as "Schienenzeppelin" rail zeppelin in 1930s german Media
Because Kruckenberg worked at Zeppelin and design his „Flugbahn-Wagen“ like later one.
