Arlington Utility

Arlington Utility is part of the Metro system under the Capital Wasteland, but the tunnel has collapsed from the continued deterioration over the years. It is an underground utility tunnel and hosts caves infested with raiders and mirelurks. It connects Arlington Cemetery North and the DCTA tunnel 014-B Potomac tunnel system.

Notable loot

 * U.S. Army: 30 Handy Flamethrower Recipes is found on the second floor in the "kitchen area". Coming from DCTA tunnel 014-B Potomac, it's past the caves, when you enter the tunnels again full of raiders. The first stairs on the right, on a shelf. From the Arlington Cemetery entrance, after you pass the "White Line" sign take your first left (a four way junction), then a right (a T intersection). The kitchen area will be on your right.
 * When you enter from the DCTA tunnel 014-B Potomac entrance, there is a first aid box with a Rad-X and a stimpak in it to the left, when you pass behind the sandbags. Two more stimpaks are on the table to the right in the same area as the sandbags (this time behind some cement blocks).

Arlington Utility appears only in Fallout 3.
