Iam

Iam was the substitute controller for Sir Topham Hatt when the later was on vacation.

Bio
As stated, Iam was the substitute controller when Sir Topham Hatt was away. Thomas caught him sabotaging his firebox, and the former later found out that Iam was sabotaging the other engines, because he thought they weren't working hard enough. Sir Topham Hatt came back to the island and banned Iam from the railway.

Personality
Iam is rather grumpy, but not much more is known about him.
