Max and Monty/Behind the Scenes

Television Series
Max and Monty are fictional twin dump trucks created by Phil Fehrle with writers Abi Grant ,Jonathan Trueman (for Max only) and Paul Larson (for Monty)

In 2002, Max made his debut in the sixth series of Thomas the Tank Engine & Friends in the episode, Jack Jumps In. Monty would later make his debut in the Jack and the Sodor Construction Company episode, On Site with Thomas. They would later appear together in the special, The Great Discovery, and one of them would appear in the twelfth series.

When the show transitioned into full CGI in 2009, Max and Monty were absent for six years. They later returned in the 2015 special, Sodor's Legend of the Lost Treasure and were some of the very few members of the Pack to return.

Since 2016, Max has been voiced by Tim Whitnall in the British English dub and Kerry Shale in the American English dub, while Monty has been voice by Rasmus Hardiker in the British English dub and Rob Rackstraw in the American English dub. Whitnall and Hardiker give the two of them British accents in the UK, while Rackstraw and Shale give them American accents in the US (though in the US dub, their voices contain faint hints of a Cockney accent). As another note, Monty's voice was deeper and hoarse in the UK dub, while it was reversed in the US dub.

Max and Monty are based on 1949 Scammell Mountaineer 4-wheel drive dump trucks.

Live-action models
The model's chassis' were built out of brass and the top was built out of plastic to keep the weight down. A small flat fan was built underneath the chassis to cause the dirt to be kicked up. The models were painted in a matte finish and the numbers were custom stickers.

There were three remotes built to control Max and Monty, one was used to control their movement, one was used to operate their dumpers, and one was used to move their eyes.

Present Day
After production of the model series wrapped in 2008, most of the models and sets would be put into storage, with some being put on display at Drayton Manor Theme Park. All other models would be logged and referenced in 2009 by HiT Entertainment, from this HiT would decide on which models were to enter storage once again, which would be given to crew members and which to be disposed off. Due to only having one set of models made, Max and Monty's models would stay under HiT and later Mattel's ownership.

Their models are currently in Mattel's storage unit in Southampton England.

CGI Model
In 2009, the series introduced Computer-Generated Imagery (CGI) as a replacement for the show's long-standing live-action models. Max and Monty were recreated from scratch in CGI by Arc Productions in 2014 for production of the 2015 special, Sodor's Legend of the Lost Treasure. Their models was "hand-sculpted" in Maya, a 3D animation and modelling software.

Max and Monty have had modifications throughout the CGI series. These include:
 * An increase in overall size.
 * Monty acquiring a slightly different bumper design and a silver radiator cap, rather than a black one.
 * Their dually rear wheels protrude out more and are closer together.
 * Tail-lights.
 * New horn sounds.
