Smokey and Steamer

Smokey and Steamer are twin brothers and the Polar Express' fireman and engineer in the 2004 film, The Polar Express. They are mo-capped by Michael Jeter and voiced by André Sogliuzzo who also voiced Puss in Boots in the Shrek video games.

Role in the Film
Smokey and Steamer are first seen at the front of the locomotive, fixing its headlamp (while facing a bit of difficulty). While doing so, they leave Hero Girl in charge of driving the train in the engine room. After the headlamp is fixed, Smokey catches sight of a light ahead on the tracks. Steamer sees it too and calls out to Hero Girl to stop the train. Hero Boy and Hero Girl get the message, but have trouble finding out which controls were the brakes. They eventually figure it out and stop the train just in time. When the train finally stops, Steamer finds himself face to face with a caribou.

A giant herd of caribou is blocking the tracks, which Steamer points out would take hours for it to clear due to there being a hundred thousand to a million. Hero Boy, Hero Girl, and the Conductor get to the front of the train to try to help. On the way, Hero Boy slips and grabs on to Smokey's beard to break his fall, causing Smokey to scream in pain. It is discovered that the caribou understand Smokey's screaming, so the Conductor continues to pull Smokey's beard to try to communicate with them. They eventually manage to get them to clear the tracks.

Smokey and Steamer go back to the engine room and get the train moving again. However, Steamer suddenly finds the throttle jammed and tries to fix it, though he forgets to notice how fast the train is going and cannot hear Hero Girl calling out to them to slow down. The pin holding the throttle falls off and slips through the grate on the floor. As the train speeds down Glacier Gulch, the pin comes out of the grate and Steamer catches it in his mouth, but swallows it.

On the Ice Lake (where the ice had frozen over the tracks), Smokey gets the pin out of Steamer's mouth by hitting him on the back with a shovel, but pin flies out of the engine room and pierces the ice, causing it to crack. With no other option, Smokey decides to use the pin from his hair to fix the throttle, allowing Steamer to stop the train. Suddenly, Hero Boy notices the crack in the ice getting bigger, prompting Smokey and Steamer to get the train off the lake with the Conductor navigating. They find the tracks on the other side of the lake, head toward them, and escape the cracking ice just in time.

The Video Game
Smokey and Steamer appear in the video game, only in the third chapter. While Hero Girl is driving the train, something goes wrong, but Smokey and Steamer return to the engine room to fix it. They ask Hero Boy to help by catching the parts that fall off and tossing them back to them. Later, after the caribou clear the track, Hero Boy helps Smokey and Steamer get the train moving again.

Trivia

 * Smokey and Steamer are two of several characters from the film to not appear in The Polar Express book. While someone must have been driving the train, it is unknown who it was since no scenes take place in the engine room.
 * In the film, the pair's names were only revealed in the credits. However, they mentioned their names, as well as them being twins (which was never revealed in the film at all), in the deleted scene, "It Takes Two".
 * While Steamer is the engineer and Smokey the fireman in the film, this is reversed in the video game.
