Train Tunnel (Fallout: New Vegas)

The train tunnel is an unmarked location in the Mojave Wasteland It is located between Raul's shack and the Brotherhood of Steel safehouse, and north of Gypsum train yard.

Layout
It is home to feral ghouls and glowing ones. It is lined with frag mines throughout, including some placed on the waist-high ledge on either side of the tunnel. Near the western exit are two bear traps. Both ends of the tunnel are locked with a Very Hard lock.

The tunnel serves as an alternative route to reach Nellis Air Force Base in order to avoid most of the shelling. It will exit just south of Nellis within view of the control tower. Follow the right-hand tracks to the fence and then head left along the fence line to avoid the bombardment.

Loot

 * Fire helmet - On a dead ghoul wastelander.
 * Construction hat - On a table in a maintenance room with a glowing one.

Bugs

 * Sometimes, the doors will not be locked and can be opened without the need to pick the lock.
 * Sometimes, it is not possible to enter the side room, in which a glowing one is waiting. The floor of the stairs is not solid, leading the player character to fall through and into the void, subsequently sent back to the tunnel entrance. The same will happen to any interactable object, corpses, and companions. No solution found yet, though, barrels found in the tunnel can be used to jump the stairs.
