Smokey and Steamer are the Polar Express' fireman and engineer.
They are first seen fixing the light in front of the locomotive (with a bit of difficulty). While doing so, they leave Hero Girl in charge of driving the train in the engine room. After they manage to fix the light, they catch sight of something on the tracks ahead and call out to Hero Girl to stop the train. Hero Boy and Hero Girl get the message, but have trouble trying to figure out how to apply the brakes. They figure it out and manage to stop the train in time. When the train finally stops, Steamer finds himself face to face with a caribou.
They soon find out that a giant herd of caribou is blocking the rails. Hero Boy, Hero Girl and the Conductor get to the front of the train. Hero Boy slips and grabs on to Smokey's beard to prevent from falling, causing him to scream in pain. They soon find out that the caribou understand Smokey's screams. The Conductor then pulls on Smokey's beard to try to communicate with the caribou until they manage to get them to clear the way and get the train moving again.
Smokey and Steamer go back to driving the train in the cab. Steamer suddenly finds the throttle jammed and tries to fix it, though he forgets to notice how fast the train is going and pays no attention to Hero Girl calling out to them to slow down. The pin holding the throttle falls off and goes through the grate on the floor. As the train goes down Glacier Gulch, the pin comes out of the grate and Steamer catches it in his mouth, but swallows it.
As the train ends up on the Ice Lake, Smokey manages get the pin out of Steamer's mouth by hitting him on the back back with a shovel. However, the plan works too well as the pin falls out of the cab and lands on the ice, causing it to crack. Smokey uses the pin from his hair to fix the throttle and Steamer manages to stop the train. Suddenly, Hero Boy notice the crack in the ice getting bigger, prompting Smokey and Steamer to get the train off the lake with navigation from the Conductor. They manage to find the tracks on the other side of the lake and escape the cracking ice just in time
