Metro

Metrorail, or simply Metro, is the rapid pre-War transit system of Washington, D.C., and neighboring communities in Maryland and Virginia. In 2277, tunnels can be used to move between the various settlements in the area, although a major part of the tunnels has been taken over by super mutants.

It is possible to activate the Metro Protectron robots by hacking into their control terminals. Once the Protectrons are functioning properly, they head out to patrol the subway tunnels and attack any super mutants who do not have a transfer handy.

Appearances
The Washington Metro appears only in Fallout 3.
