The entrance to the station is near the southern border of the map, west of Arlington Library (can be reached from Nuka-Cola plant) and across the street (north) from a raider camp. This metro is mainly caved in, and is a maze of utility tunnels and shafts filled with mirelurks of all types. Heavy firepower may be necessary. It also has a very high complex of stairs leading downwards, breaking into small rooms near the beginning. Be warned that there is a shaft in the middle of this complex; resist the temptation to jump the railing, it's a long fall.
