Old Olney Underground

Old Olney underground is a location added to Fallout 3 with the add-on Broken Steel, accessed via a ladder in Olney sewers.

Background
As part of the quest Shock Value, the Lone Wanderer passes this area to reach the Olney Powerworks. It is inhabited by two ghouls named Kidd and Wint, as well as a lot of deathclaws. The ghouls (along with several more now-deceased friends, Badger, Connelly, Dunbar, Carl and Sanders) tried to establish a colony here, but disturbed a deathclaw nest. Kidd and Wint were the only survivors.

Layout
The area can be divided in four small subsections:
 * The first is the home of Kidd, Wint and their dead ghoul compatriots.
 * The second area appears to have been a children's hospital.
 * The third area is a utility section under the hospital, which contains quite a few weapon components, such as two cherry bombs, a lunchbox, plenty of turpentine, Abraxo cleaner, and other components, along with two workbenches. There is also a small (Locked) sub-basement storeroom, which contains the remains of two dead Chinese spies next to a ham radio, a Nuka-Cola Quantum, a Chinese assault rifle, a scoped .44 Magnum, a first aid box, and two ammunition boxes.
 * The fourth area is a short tunnel and another utility section leading to Old Olney S. Wilson Building.

Skeletons, fortifications, and weapons caches throughout the hospital and basements suggest the area had seen a large battle long before the ghouls tried to establish a colony there. Relatively recent tunneling suggests one faction may have tried to burrow their way into their enemy. The identities of the combatants, the era in which the conflict took place, and the origin of the deathclaw hive remains a mystery. But a possible explanation may be rioting in or around the hospital as a result of the rapid deterioration of humanitarian conditions after the Great War.

Notable loot

 * Dunbar's note, found on the ghoul Dunbar.
 * A mini nuke is found underneath a teddy bear next to a bookshelf full of children's toys. After going up the ramp that leads to the children's hospital, turn around and there will be a hole in wall to the right where the bookshelf is located.
 * A Nuka-Cola Quantum can be found about 3/4 of the way through to the Old Olney S. Wilson Building. Once passing a small cave-like tunnel, there will be a big room with three deathclaws roaming around. Located near the middle of this room is an average locked jail cell. Inside the cell, the Nuka-Cola Quantum is behind the Ham radio.
 * Bottlecap mine, in the northwest on a workbench.
