- “I'd hate to be red like James, people would think I was a fire engine!”
- ―Henry, Fire-Engine, James and the Diesel Engines
In the Railway Series, they first appeared in the Henry the Green Engine. When Gordon jammed his whistle, the fire brigade thought it was an emergency alarm. So they stood on duty with five fire trucks.
In the television series, they first appeared in the fifth season and made several cameos until The Great Discovery. Throughout the sixth season and seventh season, they were commonly seen at Dryaw. From the ninth to twelfth seasons a fire truck was seen at the Sodor Airport.
Since Belle and Flynn's arrival, the fire engines have been rarely seen. However, one of the signs on the Sodor Search and Rescue Centre Building features a depiction resembling the same design as a Fire Engine and an Ambulance.
The fire engines resemble the Dennis F8 fire engines.
