Maximilian "Max" and Montgomery "Monty" are reckless and troublesome dump truck twins, who work for the Sodor Construction Company.


Thomas & Friends

Max first appeared without Monty when Jack came to the Pack, where he teased him and Alfie by spraying dust all over them as he rushed past them. Max then rushed towards Jack and stopped right in front of him, but Jack did not move, angrily telling Max to stop bullying.

Max and Monty once caused Patrick to have an accident with his own concrete/cement when they were arguing on who was the most important. They insulted "the One-eyed Truck" story (even before Kelly began it) and also teased Percy and Alfie about it. However, they became convinced that they were being chased by it in Maithwaite Forest, only to later learn it was actually Thomas. Max and Monty's reckless behaviour caused a water pump to burst, rendering Alfie trapped in thick mud. They also carelessly raced around the forest and crashed into the Lightning Tree. Later on, they teased Buster about how slow he was, so they had a race with him when they were testing the Sodor Racetrack. However, Buster won the race when Max and Monty bumped into each other while arguing and ended up in a ditch, although they got themselves out after a bull frightened them. Max and Monty later teased Alfie about his size and called him "Small fry" and "Half pint".

They helped with the construction of the Harwick Branch Line.

The two dump trucks later worked with Jack, Alfie and Oliver on a dig-site on Thomas' Branch Line. They took a liking to racing Thomas, but ended up performing dangerous stunts and nearly causing accidents. Later, they dumped their loads over a bridge on the line and ended up derailing Thomas and Oliver on their way back to the site. After the accident site was cleared, Thomas then decided he would not be racing against the reckless dump trucks again.

After James' accident at Tidmouth Sheds when his brakes malfunctioned, Max and Monty helped with the shed's reconstruction.

Some time later, they were sent to work in Italy with the rest of the team to help Ester build the new museum. They also witnessed the rescue of the lost engine Lorenzo by Thomas.

During the construction of a visitor's park at the Lead Mines, Max and Monty were tasked with dumping rubble in front of the mine shafts. However, they constantly teased Darcy and ignored her warnings about the mine shafts being unstable for them. The two dump trucks drove past the barriers near the mine shafts, thinking it was safe enough. Unfortunately, the ground below Monty gave way, resulting in him falling down into a mine shaft. This led to him being rescued by none other than Darcy herself. Monty thanked her for rescuing him and Max apologised for his and Monty's teasing.


Max and Monty are usually devious and reckless trucks who cause trouble for everyone they come into contact with, but are sternly scolded by Miss Jenny or any other form of authority when they are found out. They are also known to bully smaller construction vehicles, particularly Jack and Alfie, and sometimes, their reckless actions can cause serious consequences either for others or themselves. Despite being unruly, obnoxious and obstreperous at times with dangerous stunts, they both have a good, caring side (Max was visibly shocked when Jack damaged his arms saving Thomas), and are just as hardworking as the rest of their colleagues.

In later episodes, their bullying antics seem to have died down, but they are still reckless and troublesome. The two deeply care for each other, even if they argue from time-to-time.

Technical Details
