The entrance to the Metro station, just south of the Red Racer factory has long since collapsed. Thankfully, the employee entrance located next to it is still accessible.
The small interior cell connects the entrance in the Capital Wasteland to the entrance inside Bailey's Crossroads. Most of the station is buried under rubble, including the train tunnels. The remaining accessible areas are haunted by a small number of feral ghouls.
Below the mezzanine is a small area lit by glowing mushrooms. The broken toilet holds a sawed-off shotgun, some drugs, and ammunition, while there is minor loot found in the containers nearby. Interestingly, there's a cage located just in front of the cave below the mezzanine, with a skeleton inside and six bottles of water around it. Apparently, someone was caged, then left to rot, with the bottles of water placed around just out of reach to torment him.
