Warrington Trainyard

Warrington Trainyard is located just West of Tenpenny Tower in the Southwest corner of the game map and is adjacent to Warrington Tunnels. It is inhabited by Ghouls, and there is a persistent, but not great source of radiation, but plenty of Rad-X and Rad Away to be found.

Of note is the Sniper Rifle (in very poor condition) and .308 rounds located in the elevated shack to the South. (The "shack" is a couple of metal, squarish tubes in an L shape. The easiest entrance to it is from outside the trainyard. Approaching from the East, go South around the fence and up the hill.)

The PC may have to go through here for the Tenpenny Tower (quest).

To the Northwest, just over the ridge, is a Dot's Diner building that appears, however, to have no notable loot of any kind. It is likely a random encounter location.
