That cabin may seem rustic, but don't be fooled, it's the control center for Jean Bison's train empire. Sneak inside and raid his files, you're sure to find out where he keeps his Clockwerk parts.
― Bentley explaining the current job to Sly[src]
Bentley tasks Sly with sneaking into Bison's cabin and raiding his files to find the locations of his Clockwerk parts. Sly launches himself off a wall hook to reach the cabin. Inside, he finds Bison having a phone conversation with Arpeggio. While taking photos of Bison's train routes and eavesdropping on the conversation, Sly learns that Bison has put three of his Clockwerk parts into the engines of three of his trains, which he calls his "Iron Horses". This improvement helps the trains to run endlessly. He has also hidden the blueprints to each Iron Horse in three different cabins.
Sly steals the first set of blueprints from the trophy bass above Bison's fireplace, and leaves to obtain the rest. After stealing the other two sets of Iron Horse blueprints, Sly climbs up to a satellite dish on top of a mountain. Armed with the blueprints, he is able to use the satellite dish to access the trains' GPS data, which Bentley now has on his computer. Bentley tells Sly to come back to the safehouse so he can give him and Murray the run-down.
- After completing this job, any character can go back into Jean Bison's cabin and attempt to fight him. However, he is invulnerable and cannot be defeated.
- Also, an error in development causes him to make the same noises as Dimitri Lousteau when attacking him.
