Max and Monty

Max and Monty are twin troublemakers who work in the Sodor Construction Company

Personality
Max and Monty are rude bullies, who often make fun of the others. However, things never turn out the way they want it to, as seen in The Tortoise and the Hare. They feel embarrassed when this happens, yet still make it a priority to be mean. They think they own everyone and think the world revolve around them.

They are also very careless, and often accidentally damage something because they were not paying attention, as seen in A Happy Day for Percy, when they broke a water supply pipe, and sent Alfie to sink into the mud. He was saved by Byron.

Trivia

 * They like to race Thomas, as seen in Sodor's Legend of the Lost Treasure.
