Ace posted:Video: A Gauge 1 Propellor driven Rail-Zeppelin/Schienen-Zeppelin
Prop drive, no details on who made this.
I notice the prop shaft has a slight angle to place slight downward thrust on the body. Shouldn't be rocket science to build something for O-gauge.
That looks very much like a "Rail Zeppelin" model that has been issued and I think re-issued by Marklin in both HO and 1 gauge and indeed also Z scale. Details on the HO version here:

I'm not sure that the propeller actually drives either model. The HO parts list clearly shows a geared and powered front truck with a separate motor for the prop over the rear truck. Of course if you want to blast your track ballast I guess you could have the prop truly functional.
Once I nearly got one just for curiosity value (I have some Marklin 3rail HO sets) but never actually followed through.
I've never seen an O scale version of these rail cars.
