Muir

Muir is an old steam locomotive in Planes: Fire & Rescue who works at the Piston Peak National Park.

Planes: Fire & Rescue
In Planes: Fire & Rescue, he is seen puffing along a train track as Dusty Crophopper flies past him.

Trivia

 * Unlike the steam train seen in Planes, Muir's mouth is on the front of his steam motor instead of his cowcatcher.
