A doodlebug is a type of small, self-propelled railcar that was used for short-distance passenger travel, particularly on low-traffic or rural railway lines. Often smaller than traditional trains, doodlebugs were designed to be efficient and economical for carrying a few passengers over shorter distances. These railcars usually had their own engine, allowing them to move without needing a separate locomotive. Doodlebugs were commonly used in the early to mid-20th century but have largely been replaced by more modern rail vehicles.
