Smudger was very cocky and rode dangerously, which led to his ultimate downfall. The Mid-Sodor controller took his wheels away and made him into a generator. Duke had did his best to keep the fiesty little engine in line, but to no avail. In his heyday, Smudger had a plethora of accidents and caused a great deal of damage. To this day, Duke seems to be obsessed with recollecting on Smudger's various mishaps.
It is expected that Smudger was left behind in the back of the shed when Duke was rescued.
Smudger is reckless, haughty, and perpetually prone to mishap. He never acknowledges his accidents as mistakes and seems to take no notice of the damage he has caused. Although he had a deep respect for Duke, he did not listen to his advice, and this alone would have changed his fate. For many years, he held a deep resentment for the Railway and its superiors, and perhaps the friend that had left him behind.
