Big MT west tunnel is a location in Big MT in 2281.


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.

Notable loot


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