The town has a commuter railroad station on Metra's Union Pacific/West Line with service to downtown Chicago.
Berkeley is on Cook County's western border, 14 miles west of the Chicago Loop. With Interstates 290 and 294 forming its western and part of its southern boundary, and the Union Pacific Railroad (formerly the Chicago & North Western) and the large Proviso Railyard (a classification yard) to the north, Berkeley has ready access to the metropolitan region. Yet the transportation corridors that make Berkeley accessible to distant places also serve to separate the village from its nearest neighbors, creating a small-town atmosphere.

According to the 2010 census, Berkeley has a total area of 1.4 square miles (3.63 km2), all land.
Beginning in 1835 the area that was to become Berkeley was home to farmers, most of German and Dutch ancestry. Settling on farms that ranged from 40 to 160 acres, the Dutch tended to be truck farmers, while the Germans did general farming. This small group of farm families established a one-room school called Sunnyside in 1848. Now housed in a larger and newer building, Sunnyside Elementary School still operates today.
