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 Courier 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 - a paper note, can be found on the left terminal by reading entry 6.
- Cuddles' toy car, a unique version of the toy car. On the table next to a terminal. Will be named toy car before reading entry 5.
The prison building appears only in Fallout: New Vegas.
