Tabitha came in today and said she's concerned about my safety. She's insisted that I change the lock on my door to require a password, using one of the other computers I fixed. I'm really starting to regret ever fixing those.”— Raul, entry 6 on his terminal
The prison building is the closest building to you as you enter the radio station building area at the top of Black Mountain.
Raul Tejada, Black Mountain's ghoul mechanic, is imprisoned in this building. The door to his room is locked; the player must must either have a Science skill of 100 to hack the nearby terminal, a key to open the door, or by accessing the second terminal near the building's entrance, and reading entry 6. This gives you the password, which is 123456789, to unlock the door without hacking the terminal. Once freed, Raul Tejada can be recruited as a companion.
- Black Mountain prison password - holotape, can be found on the terminal.
- Cuddle's toy car, a unique version of the toy car.
The prison building appears only in Fallout: New Vegas.
