Ane, even further back in time, before the 1960's, they had weed burners.
On youtube.com there is a collection of home movies called the “Bob Chester” series. One movie is devoted to Frisco and shows a weed burner in action. I believe these machines burned a significant amount of ties along with the weeds.
No working O gauge model of this machine has been attempted...hehe.
