In the Broken Steel DLC, in the cutscene used for when the player character travels on the Presidential metro, the moving train is not a separate entity programmed to move on its own due to limitations with the Gamebryo engine. Instead, when the player goes on the metro, a script is triggered that equips an NPC underneath the train with a glove that turns its right hand invisible and produces the model for the Presidential metro car on top of it appearing like a giant hat. This then triggers an animation of the NPC's model sitting down and gliding along the ground in an arc that simulates the metro riding along the subway tracks.

Rivet City's Abraham Washington is the name of this NPC and is a reference to two former United States Presidents, George Washington and Abraham Lincoln.
