Mmm... that was a nice little, uh, catnap. How long was I out?

Light Switch 02, after being re-activated with the personality tape found here

The Big MT north tunnel is a location in the north of the Big MT in the Fallout: New Vegas add-on Old World Blues.


The subway tunnel shaft has a door to the right of the entrance and a hole in the floor. There is an overclocked turret guarding the hole, and a force field covering it. Once breached, the hole leads into a cave with a LAER and some crates.

Notable lootEdit

  • Light Switch 02 personality tape, on a shelf behind the door to the right of the entrance, leaning against one end of the toolbox. The door may need to be closed for it to be visible.
  • There is a LAER down from the hole.


On the left front wall of the arch, and the left side of the train car that is still sitting properly on the tracks, there is an Old World Flag painted in white, left there by Ulysses.


The Big MT north tunnel appears only in the Fallout: New Vegas add-on Old World Blues.
