The Cable Car Barn (1201 Mason Street) is a landmark in San Francisco.
Inside, there was an square area with 9 pylons, enclosed in an electricity fence, patrolled by Robot guard; it could be traversed only by cable cars. One of the pylons had a switch that opens a door to the fence. Nearby are cable cars with piles of human corpses. One car has posters of New York and London.
Day 2[]
One slave secretly met a Dragon in the Barn and brought him a message: "They have almost reached Life. Bring us to Hell and we will show you Freedom. Beware the surface robots. Please hurry!" Before the Dragon could bring it back to the Dragon Clan, Phil Cook and a Ratman had followed him there, assaulted and killed him. They left his body in a pile of other corpses.
The Manhunter rode a car into the barn, and dropped in the enclosed area; avoiding the patrolling robots he flipped the switch to access the external area with the cars; he found the Dragon's body and the note.
Day 3[]
When The Manhunter reached Hell, he flooded several Orb-controlled buildings with lava, including the Barn.
