Fallout: New Vegas locations project
Big MT west tunnel
Unlike other train tunnels, the west tunnel does not have a train rammed through the door. The entrance leads to a subway tunnel. To the right of entrance is an Easy locked door that leads to a small room, and the next two doors to the right lead to a network of maintenance tunnels filled with protectrons scaled to the players level, along with a unique protectron named The Custodian. The tunnels end with a Hard locked door that leads into a subway tunnel, which is caved in on both ends; there is assorted loot in this tunnel.
- The Recipes - Unarmed skill book is through the Easy locked door to the right of the entrance.
- The Main Computer Upgrade: LAER Mod "Auxiliary Recharger Chip" is found by heading down along the entrance, taking a right at the first opportunity, then going straight through the door ahead. The upgrade is on a shelf wedged between a duffle bag and the side of the shelf.
- A Saturnite fist in the northwest tunnel behind the Average locked door next to a skeleton.
