Nevada

Nevada is a pre-war state in the United States. Before the Great War, it was part of the Southwest Commonwealth, along with Southern California and Hawaii when the country was divided into thirteen commonwealths.

Locations
New Reno, Broken Hills, Vault City and Gecko, a quite diverse collection of towns, are all in former Nevada state territory. However these towns (except Gecko) are present at Vault City Northern California Travel Log. Jules refers New Reno as side part of California also (Cee-Ay).

Two explanations of this inconsistency are possible:
 * Western part of Nevada state was incorporated into Northern California state,
 * Opposite to Southern California, where the New California Republic is located, inhabited areas north from it are called Northern California.

Tycho's father mentioned Las Vegas and a fat mobster there. Las Vegas localization is beyond eastern edge of the Fallout worldmap (and beyond western edge of Van Buren worldmap, 30 miles north-west of Hoover Dam).

Hoover Dam lies on the border between Nevada and Arizona. The NCR supply train sometimes arrived to Hoover Dam from the west.

Desert Rangers
Desert Rangers were a faction living in the Nevada area during Vault Dweller times. They were descended from people who had survived the devastation of the Great War, likely living among the badlands of Nevada. This small community kept a strong survivalist contingent - so they still had some small arms and books. They probably had something like the cliff-dwelling Indians going on for their town. Tycho was one of them. The Chosen One didn't meet the Desert Rangers in the western part of Nevada (Fallout 2 area, 2241-2253 year).

Railways
In the real world there are two class I railroads in Nevada:
 * from southern California (Los Angeles region) to Salt Lake City, Las Vegas is stop there,
 * from San Francisco and Oakland, via Sacramento, to Salt Lake City, Reno is nod there (there is small one bond railway station in eastern part of New Reno).

According to Hoover Dam and Boulder design documents Hoover Dam was connected by railroads with western parts of the NCR, Fort Aradesh, Boulder and Denver.

Because of Powder Gangs operations line from Hoover Dam to Fort Aradesh become inoperable.

Appearances in games
Fallout 2 takes place partly in Nevada, as would Van Buren if it were finished and as will Fallout: New Vegas. Nevada was mentioned by Tycho in the original Fallout.
