Humphrey is a freight diesel who lives at Cliffstone Mountain Junction yards.
The biggest freight engine of the Dream Fleet, Humphrey is a bit loud, but has an equally big heart. He's nicknamed Tracy "Peanut Roaster", but he only does it in a friendly, teasing manner to the peppy little engine.
Humphrey is not based on a specific prototype.
Humphrey is dark green with sky blue and black stripes. He has black horns and a bumper with orange and black stripes.
- Soeren Hermansen is responsible for naming Humphrey. In the original 2011 'Little Engine That Could' movie, he was named 'Frieght Train'.
